A r t . 252.—D e f in it io n s a) R e c o g n iz e d p ro d u c tio n c a rs : cars o f w hich the series-p roduction o f a certa in num ber o f identica l (see d e fin itio n o f th is word hereafter) cars, has been com pieted w ith in a certa in period o f tim e, and w hich are m eant fo r the norm al sale (see below) to the Ind iv idual purchaser. Th is period o f tim e is o f 12 consecutive m onths. The checking o f the ex is ting m inim um p.’'oduction enables the A O N to apply to the F IA fo r recogn ition (see th is w ord below).

b) E x p e rim e n ta l c o m p e t it io n c a rs : cars w hich have noth ing or w hich have no more to do w ith a se ries-p roduction vehicle, e ither th a t on ly one o f the type has been bu ilt, o r th a t the num ber o f un its w hich has been b u ilt is in fe rio r to w hat is required fo r the group fo r w h ich the m inim um num ber o f un its annua lly produced is the sm allest, o r tha t a lthough they orig ina te from a se ries-p roduction car, they have been m odified or equipped w ith new accessories to the p o in t th a t the ir se ries-p roduction nature has been lost.

c ) R a c in g c a rs : cars m anufactured solely fo r speed races on a c irc u it o r a

closed course. These cars are generally defined by the in te rna tiona l racing fo rm u lae the spec ifica tions o f w hich are fixed by the F IA fo r a certa in period of time. Racing cars not being defined by any in ternationa l fo rm u la are said to be “ fo rm u le lib re ” and th e ir sp ec ifica tions m ust in th a t case be set ou t in the supplem entary regu la tions of the event.

d) Id e n tic a l: by “ iden tica l” cars are meant cars be longing to one and the same fab rica tion series and w hich have the same coachw ork (ou ts ide and Inside), same m echanical com ponents and same chassis (even though th is chassis may be am algam ated w ith the coachw ork in case o f a unitary construc tion ).

“ M echanical com ponents" inc lude a ll parts fo r the propu ls ion , suspension, steering and braking system and a ll accessories w hether m oving or n o t w hich are necessary fo r th e ir r^ormal fu n c tio n in g (such as fo r instance, e lectric accessories).

By chassis is m eant the s tructu re o f the car w hich holds m echanical com ponents and coachw ork together, and inc ludes any struc tu ra l part w hich is located below the horizonta l plane passing th rough the centre o f the wheel hubs.

e) M in im um production : th is m inim um production, d iffe ren t fo r each group o f cars, applies to cars w hich are identica l, the m anufacturing o f w hich has been fu lly com pleted w ith in a period o f 12 consecutive m onths.

By "m in im um series” should be understood on ly a number o f entire ly fin ished cars, eg, cars in runn ing condition and ready fo r delivery to the purchasers.

f) N orm a l sa le : means the d is trib u tio n of cars to ind iv idua l purchasers th rough the norm al com m ercia l channels o f the m anufacturer.

g ) R eco g n itio n : is the o ffic ia l ce rtifica tio n made by the F IA th a t a m inim um num ber o f cars o f a spec ific model has been made on se ries-p roduction term s to ju s t ify c lass ifrca tlon in group 1 ,2 ,3 ,4 , o r 5 o f these regulations. A p p lica tion fo r recogn ition shall be subm itted to the F IA by the A C N o f the coun try in w hich the vehicle Is m anufactured and shall enta il the draw ing up of a recogn ition form (see below). It m ust be estab lished In accordance w ith the special regulations, called “ Regulations fo r R ecogn ition ", laid down by the F IA , and a m anufacturer w ish ing to obta in the recogn ition o f h is model(s) m ust undertake to abide by the ir p rescrip tions. R ecognition w ill only be granted to car-m ode ls w hich were s till in p roduction on 1st January 1969 or the production o f w h ich was started after th a t date. R ecognition o f a series-produced car w ill become void 4 years after the date on w hich the series-p roduction o f the said model has been stopped.

R ecognition of a model may only be valid fo r one group. The transfe rring o f a previously recognized model from one group to another w ill therefore n u llify the e ffect o f the said previous recognition.

Defin itive abandonment o f the series-productionThe series production is regarded as com pletely stopped i f the m onth ly rate has

decreased fo r more than four consecutive m onths to below 1/12th o f the m inim um figure required by the Appendix " J ” fo r the m inim um production o f the group in which the model is recognized.

D efin ition o f the term "m ode l o f car"By "m ode l o f ca r" is meant a ll the cars belonging to a production series d istingu ish

able by a specific conception and specipc external general lines o f the coachwork, and by an identica l mechanical conception o f the engine and the transm ission to the wheels.

A m odel o f car may exist in several variants (fo r example, d ifferent power o r engine cylinder-capacity), which may possib ly be the subject o f separate recognitions.

101

However, taking the A rt. 252g as a basis, it m ust be pointed out that, i f the Sub- Commission fo r Recognitions has the possib ility, fo r practical reasons, to authorize the recognition o f certain variants o f a same car-m odel in d ifferent Groups o f cars, the princip le o f a simultaneous recognition o f variants o f a same m odel in Groups 1 and 2 {Touring Cars) on the one hand, and in Groups 3, 4 and 5 {Grand Touring and Sport) on the other hand, remains forbidden.

h) R e c o g n it io n fo rm s : all cars recognized by the F iA shall be the sub jec t o f a descrip tive fo rm called recogn ition fo rm on w hich shall be entered all data enabling iden tifica tion o f the said model.

To th is e ffec t only the standard recogn ition fo rm s and standard additional fo rm fo r ‘ ‘ norm al evolution o f the type” and “ varian t” approved by the F IA shall be used by a il A C N s.

The p roduction of the fo rm s at scru tineering and/or at the s ta rt may be required by the prom oters w ho w ill be entitled to refuse the partic ipa tion o f the en tran t In the event In case o f non-p roduction .

In case o f any doub t rem aining a fte r the checking o f a model o f car aga inst its recogn ition fo rm , the scru tineers w ou ld have to re fer e ither to the m aintenance booklet published fo r the use o f the make’s d is trib u to rs o r to the general cata logue in w hich are lis ted all spare parts.

It w ill rest w ith the com petito r to obta in the recogn ition fo rm and, if need be, the add itiona l fo rm s concern ing h is car, from the A C N o f the m anufacturing country o f the vehicle.

Wheriever the scru tin iz ing o f a car shows the complete compliance o f i t w ith its recognition form , inasmuch as is required fo r the group in which i t is adq^itied, there is no need to w orry about its year o f fabrication.

Therefore, the chassis and engine numbers which may be mentioned on the recognition fo rm are not to be taken in to consideration.

i) C y lin d e r -c a p a c ity c la s s e s : the cars shall be d is tribu ted in to the fo llow ing 13 classes, accord ing to th e ir cy linder-capacity:

A = H igh-pressure nozzle area—expressed in square centim etres by w hich is m eant the area o f the a ir-flow at the exit from the sta to r b lades (o r a t the exit from the firs t stage if the s ta to r has several stages). M easurem ent is done by taking the m inim um area between the fixed blades o f the h igh pressure tu rb ine f irs t stage. In cases where the f irs t stage tu rb ine s ta to r biades are adjustab le , they w ill open to th e ir greatest extent to p resent the greatest area fo r the determ ination o f area “ A " .

The area o f the high pressure nozzie is thus the product—expressed in square centim etres—of heigh t by w id th and by the num ber o f vane spaces.

C = C yllnder-capaclty o f recip rocating p iston engine expressed in cubic centimetres.

R = T h e pressure ra tio i.e. the ra tio o f the com pressor o f the tu rb ine engine. Th is pressure ra tio is obtained by m ultip ly ing toge ther a value fo r each stage of the com pressor, as ind icated hereafter:S ubson ic axial com presso r=1 .15 per stage.T rans-son ic axial com presso r= 1 .5 per stage.Radial com presso r=4 .25 per stage.Thus a com pressor w ith one radia l and six axial stages w ill be designated to have a pressure ra tio o f:

The new cy linder-capacity o f the car shall always be considered as the real one. T h is shall particu la rly be the case fo r assign ing the car to Its cylinder-capacity class, and the car w ill be treated In ail respects as if its cy linder-capacity thus increased was^ its real capacity. Especially in regard to its c lass ifica tion per cylinder-capacity class, its inside d im ensions, its m inim um num ber o f seats, etc.

A dynam ic a ir in le t fo r ducting the a ir from the atm osphere in to the engine intake w ill not be considered as a supercharg ing device.

i) C o a c h w o rk : by coachw ork is meant:— externally; all parts o f the car licked by the air-stream and situated above a

plane passing th rough the centre o f the wheel hubs.— in te rna lly ; ail v is ib le parts o f the passenger com partm ent.

C oachw orks o f one same m inim um series shall be Identical w ith the only exception o f a "s u n ro o f” .

However, If a mode! has Its coachwork equipped w ith a sp ec ific num ber of doors arid has been recognized on the basis o f a given m inim um series, s im ila r recogn ition rnay be granted to another coachw ork w ith a d iffe ren t num ber of doors when Its m inim um production reaches 50% o f the figure necessary fo r recogn ition o f the basic series, p rov id ing th a t both m odels have the fo llow ing com m on characteris tics :

1) a coachw ork o f s im ila r shape, i.e. o f w hich the general appearance is basica lly the same and w hich has n o t been m odified beyond w hat Is necessary to change from a fo u r door version to a tw o doo r version (o r vice-versa);

2) exactly Identical m echanical parts ;3) the same wheelbase, track and num ber o f seats;4) a t least the same w eight;5) an F IA decis ion to recognize th is variant coachw ork and to draw up an

A s fa r as convertib le cars are concerned, these m ust com ply In all respects w ith the sp ec ifica tions applying to closed cars If they run an event under th is fo rm , o r w ith the sp ec ifica tions concern ing open cars if they run w ith the hood down or the hard top removed.

m ) Use o f aerod ynam ic devices on cars o f groups 5, 6, 7 and in ternatio n a l racing fo rm u la e : in In terpreting A r t 252(1), shall de fin ite ly be considered as coachw ork a ll external parts o f the ca r w hich extend above the h ighest po in t o f e ither the fro n t o r rear wheels (w ith tyres) w ith the exception of un its defin ite ly associa ted w ith the fu n c tio n in g o f the engine or transm iss ion and the anti-ro ll bar.

A n y sp ec ific part o f the car w hich has an aerodynam ic In fluence on the s tab ility o f the vehic le m ust be m ounted on the entire ly sprung part o f the car and shall be firm ly fixed w h ils t the car is in m otion.

Neither the safety ro ll bar, nor any o f th e un its associated w ith the fu nc tion ing o f the engine or transm iss ion shall have an aerodynam ic e ffect by creating a vertical th rus t.

A ll external p ro jec tions sw ing ing in a horizonta l plane shall have a m inim um radius o f 1.5 cm . The leading edge o f any aero fo il fixed to the fro n t o f the car shall not be sharp.

n) M in im um w e ig h t: Is the real m inim um w eight o f the em pty car (w ithou t persons or luggage aboard) fu lly equ ipped and ready fo r delivery to the purchaser. It shall consequently Include a spare-wheel equipped w ith a ty re s im ila r to those m ounted on at least 2 o f the 4 wheels, and all the accessories norm ally mounted on the least expensive model o f the series concerned being removed, except fo r the norm ally supplied repa ir k it (jack, to o l-k it). A l l liqu id tanks (o f lubrication , cooling system , braking, heating system , If need be), except fo r the fue l tank, m ust be fu ll.

The m inim um w eight o f the car m entioned on the recogn ition fo rm shall be

The maximum steering radius shall be 6.75 m w hich means th a t the car m ust be able to make a com plete tu rn in both d irec tions w itho u t the wheels going beyond tw o parallel lines drawn on the ground 13.50 m apart.

b) C o a ch w o rk ; m inim um inside d im ensions and m inim um num ber of seats: cars shall be equipped w ith a m inim um o f tw o seats or a m inim um o f fo u r seats accord ing to the group in w hich they seek recogn ition and, w ith in a same group, accord ing to th e ir engine cylinder-capacity.

For each group specified in these regulations, the m inim um num ber o f seats is lis ted hereafter and the m inim um inside d im ensions fo r both cases are in d icated in the fo llow ing paragraphs.

1st case (see d iagram 1); car equipped w ith 4 or (m ore) seats.The heigh t at the fro n t (B) is measured between the low est po in t o f the fro n t

seat cushion com pressed by a standard m ass,o f 60 kgs (see d iagram 2) and the ce iling (the padding if any, may be com pressed). Should the backrest o f the fro n t seat(s) be inc lined backwards, the protected heigh t m ust a lso be measured at the sam e angle as the inc lina tion o f the backrest,

— If the fro n t seats are separate, the measurem ent is made in the m iddle o f the tw o seats. In case o f ad justab le fro n t seats, the seats w ill be placed in medium position .

— If there is a com m on fro n t seat, the measurem ent is made at 25 cm from the centre line o f the car.

The heigh t a t the back (D ) is measured between the cushion o f the rear seat, com pressed by the standard mass, and the ce iling (the padding, if any, may be com pressed) at 25 cm from the centre line o f the car. Should the backrest o f the rear seat be inc lined backwards, the protected heigh t m ust also be measured at the same angle as the inc lina tion o f the backrest.

The w id th over the fro n t seats (C ) Is measured along the vertical plane passing th rough the centre o f the standard mass, 30 cm above the com pressed seat, and between the upper s trip o f each fro n t door.

The w id th over the back seats (E) is measured along the vertical plane passing th rough the centre o f the standard mass, 30 cm above the com pressed seat and between thé upper s trip o f each back door, o r at the same he igh t as fo r the fro n t seats when there are no rear doors.

N B : D efin ition o f th e w id th C and E as from 1st Jan uary 1972.

The tw o above paragraphs w ill be m odified as fo llow s as from 1st January 1972:The w id th over the fro n t seats (C ) is measured a long the vertical plane passing

th rough the centre o f the standard mass placed on the seat. The w id th m ust be freely m aintained over a heigh t o f at least 25 cm.

The w id th over the rear seats (E) is measured along the vertical plane passing th rough the centre of the standard mass. The w id th m ust be free ly m aintained over a he igh t o f a t least 25 cm.

2.— k m ust measure at least 15 cm and the m inim um m easures fo r the foo t- space o f the rear passengers m ust be: 32 cm long, 5 cm h igh and (fo r each one o f the tw o passengers) 25 cm wide.

3.— the space available fo r the rear passengers m ust meet the fo ilow ing cond ition : k - f l - f m = 9 5 cm m inim um .

4.— cars In w hich the back o f the rear seat(s) is inc lined fo rw ard beyond the vertical cannot be considered as four-seaters.

The measuring o f the above d im ensions m ust be carried o u t under the fo llow ing co nd itio ns :

— the fro n t seat, i f adjustable, m ust be placed in Its norm al d riv ing position , i.e.: K - f L - f M m ust measure at least 120 cm.

— if the fro n t o r rear seats have rec lin ing backrests (by means o f e ithe r a m echanical device or chocks), these shou ld be set a t an inc lina tion o f 15° backwards.

— K Is measured horizonta lly from th e brake pedal (a t rest) to the fo rem ost po in t o f the fro n t seat; k Is measured horizon ta lly a t a he igh t equal to I from the back o f the fro n t seat to the fo rem ost p o in t o f the rear seat.

L and I are measured ve rtically from th e h ighest p o in t o f the cush ion o f the seat to the flo o r o f the car. A t the fro n t L m ust be measured a t the usual resting- p lace o f the d rive r's heels.

M and m are measured horizonta lly from the fo rem ost p o in t o f the seat to the backrest to be measured at a he igh t o f L (I).

Tw o sp ec ific cases m ust be d is tingu ished :1) bucket-seats: the m easuring m ust be taken on the centre line o f each seat.2) com m on seat: m easuring m ust be carried ou t a t 25 cm fro m the long itud ina l

axis o f the vehicle. .However, fo r the rear seat(s) m easuring m ust be made in the same vertical

plane as fo r the fro n t seats.p Is measured (In the same vertical p lane as m) horizon ta lly from the rearm ost

po in t o f the backrest o f the fro n t seat to the backrest o f the rear seat.The seating cushion . If adjustab le in height, m ust be fixed at ha lf the adjusting

range.For the above-m entioned m easurem ents, seats m ust no t be occupied.

— By seat-back or backrest is meant the surface measured upwards from the bottom o f the spine o f a person norm a lly seated,

— By seating cushion is meant the surface measured forwards from the bottom o f the spine o f the same person.

These two main parts o f the seat m ust form an homogengous construction and be entire ly covered w ith upholstery {fo r example, in natural or synthetical textiles).

When examining a specific car, the rear space reserved fo r passengers can only be considered as com plying w ith the term "seat” i f i t offers com fort s im ila r to that o f the fro n t seat, ie, the upholstery on i t m ust have approximately the same thickness and the same fle x ib ility as that o f the fro n t seats, or, in practica l terms : during the measurement, the standard mass (60kg) m ust compress the seating cushion on the rear to approximately the same extent as on the fro n t seats.

2nd case (see d iagram s 4 and 5); cars w ith a m inim um o f 2 seats.The tw o seats m ust be d is tribu ted equaily on e ithe r s ide o f the long itud ina l

centre-line o f the car and at the same level, regard less o f th e ir norm al play fo r a d jus ting them to the size o f the driver. The loca tion provided fo r p lacing or housing the seats m ust have a m inim um w id th o f 40 cm m aintained all a long the depth o f the seat.

The “ protected h e igh t" shall be at least 80 cm measured from the cush ion of the seat com pressed by the standard mass (see diagram 2) to the ce iling (any existing padding being com pressed) in cars w ith c losed coachw ork and 80 cm from the surface o f the seat com pressed by the standard mass (see d iagram 2) to the upper edge o f the w indscreen (m easured vertica lly th rough the centre of the standard mass) in case o f open cars.

The m inim um in te rio r w id th over the fro n t seats (see m easurem ent C) shall be o f 100 cm in cars w ith a cylinder-capacity in fe rio r o r equal to 700 cc, 110 cm in cars w ith a cylinder-capacity from 700 cc to 2,000 cc and 120 cm in cars w ith a cylinder-capacity exceeding 2,000 cc.

Th is space shall be such as to enable to carry w itho u t special d ifficu lty a num ber o f su lt-cases, sheltered from rain o r d ir t w hich varies accord ing to the cy linder-capacity o f the engine equipping the car (see below ), o f the fo llo w in g m inim um d im ens ions; 60 cm X 40 c m x 2 0 cm.C ylinder-capacity in fe rio r o r equal to 2,000 cc : 1 su it-case,Cylinder-capacity superio r to 2,000 cc : 2 su it-cases.

However, in cars having Inside d im ensions w hich are In fe rio r to the m inim a laid down in a rtic le 253 b to a llow c lass ifica tion as a four-seater, but w hich conta in a com partm ent behind the fro n t seats liab le to receive passengers, th is com partm ent may be taken Into accoun t as luggage space w hether o r not It has been equipped fo r th is purpose but w itho u t m odify ing any o f the o rig ina l parts.

I) S tarting : cars m ust be equipped w ith a device and Its source o f power fo r autom atica lly sta rting the engine and able to be actuated by the driver s ittin g at the wheel.

j) Fuel tanks : the to ta l capacity o f the fue l tanks (m ain and add itiona l) m ust not exceed the fo llo w in g lim its :

Cars up to 700 cc o f engine cy linder-capacity : 60 I.Cars from 700 cc to 1,000 cc cylinder-capacity : 701.

„ „ 1,000 cc to 1,300 cc ,, „ : 801.„ „ 1,300 cc to 1,500 cc „ „ ; 901.

W ill be considered as a fue l tank any conta ine r ho ld ing fue l w hich can flo w out by any method e ithe r to the main-tank or d irectly to the engine.

The fillin g -p o rt(s ) (and vents) o f each tank m ust a lways be outs ide the passenger-com partm ent and be entire ly leak-proof.

S a fe ty ty p e fue l tanksThe FIA has fo llowed w ith great interest the introduction on the car accessory

market o f safety type fue l tanks, generally in the fo rm o f a tank In norm al sheet steel with a layer o f rubber Inside (so called "b la dd e r" type tanks) but sometimes also entire ly made o f synthetic material.

In order to prom ote the use o f these tanks which are a considerable Improvement In the drivers' safety, and to avoid any k ind o f adm inistrative com plications (confo rm ity o f the cars w ith the ir recognition form s, etc.), the use o f safety type fue l tanks w ill be allowed and even recommended fo r a il groups o f cars o f Appendix J and In a ll m otor sport events.

Nevertheless, fo r cars o f groups 1 and 3 o f Appendix J, the fitt in g o f safety tanks w ill be allowed only I f the manufacturer o f the car has recognized them as such and provided they do not exceed the capacity o f the orig ina l tanks as stated on the recognition form .

Location of fue l tanks : The emplacement foreseen by the manufacturer fo r the fue l tank(s) and the feeding system towards the engine, constitutes one o f the principles o f series-production, and th is im plies that no change can be made, unless an authorization Is explic itly stated In Appendix J.

However, a derogation to the above rule shall be made fo r cars in which the manufacturer has placed the fue l tank Inside the passenger compartment, and close to the occupants.

In th is specific case, and fo r the sake o f safety. I t w ill be possible, whatever the group o f cars, to m ount a leak-proof protective barrie r between the tank and the passengers,

121

or to change the place o f the tank and, i f necessary, Its accessory parts ( fil lin g port, petro l pump, outlet tube).

k) S p a re -w h e e ls : all cars shall be equipped w ith at least one spare wheel w ith its tyre occupying the position provided fo r by the m anufacturer w hich may not encroach upon the space provided fo r luggage.

The spare wheel m ust be equipped w ith a tyre o f the same d im ensions as those fitted on at least tw o wheels o f the car.

I) S ilen ce r (m uffler) and exhaust sys te m : even when the spec ific provis ions fo r a group a llow replacem ent o f the orig ina l m uffler, cars com peting In an open road event shall always be equipped w ith an exhaust m uffle r com plying w ith the road regu la tions of the coun try(ies) th rough w hich the event Is run.

For events run exclusively on closed c ircu its , the supp lem entary regulations may authorize m od ifica tion , replacem ent or removal o f the exhaust m uffler.

The outle t pipes o f the m uffler shall be directed e ither rearw ards or sideways. If the ou tle t pipes are po in ting rearwards, th e ir o rifices shall be placed a t a height neither superio r to 45 cm nor below 10 cm ; they shall not p ro trude by more than 15 cm beyond the overall length o f the car. If the exhaust p ipes are directed sideways, th e ir o rif ice s m ust be located a ft o f a vertical line passing th rough the wheelbase centre and may not p ro ject in any way beyond side o f the coachwork. A dequate protection shall be provided in o rder to prevent heated p ipes from causing burns.

m ) S a fe ty d e v ic e s : fo r all cars com peting in events entered on the FIA In ternational S porting Calendar;

— a supplem entary locking device fo r engine bonnet, boot lid , and any other im po rtan t ob jects carried on board o f the vehicle, such as spare wheel, too l set, e tc;a supplem entary protection o f all fue l p ipes and brake lines outside the coachw ork aga inst any risk o f damage (stones, co rros ion , breaking of mechanical pieces, etc) and inside the cockp it aga inst any risk o f fire (fuel pipes on ly);

— anchor fitt in g s fo r safety harness;— a w indscreen o f safety g lass o f the lam inated type;

during the event, the car shall carry a dry chem ica l fire -ex tingu isher o f at least 1 kg capacity. It may be located in the space provided fo r the passenger, the fitt in g o f a safety ro ll-ba r o r cage in com pliance w ith the fo llow ing prescrip tions.

Cars o f Groups 1 to 4

It is com pu lso ry to f i t a safety ro ll-b a r o r cage fo r all speed events (c ircu its or h ill-c llm bs).

For regu larity events (ra llies), the fitt in g Is com pulsory fo r specia l cars (G roups 2 and 4), and optiona l fo r se ries-p roductlon cars (G roups 1 and 3). However, shou ld the organizers o f a ra lly deem th a t the driv ing co nd itio ns during the ir event are c o m p ta b le to those o f a speed event, they are entitled to prescribe the com pu lso ry fitt in g o f a safety ro ll-ba r o r cage, even fo r cars o f G roups 1 and 3. Th is ob liga tion m ust, In th a t case, be clearly m entioned In the Supplem entary R egulations o f the event.

The atten tion o f racing drivers is drawn to the fa c t tha t a safety ro ll-bar can be e ffic ien t only if the driver is firm ly m aintained In h is seat by a safety harness. In the oppos ite case, the safety ro ll-bar. Instead o f p ro tecting the driver, constitu tes a dangerous obstacle inside the passenger com partm ent.

123

The exact w eigh t o f the device shall be sub ject to a s ta tem ent from the com petito r, to be appended to the entry form . Th is w eigh t m ust be added to that ind icated fo r the vehic le on the recogn ition form .Closed Cars

A s a générai rule, the safety cage m ust be made o f tw o main hoops, one behind the fro n t seats and one fo liow ing the w indscreen p iiiars.

However, fo r p ractica i reasons, the fitt in g o f such a cage is made com puisory oniy fo r cars o f w hich the w eigh t declared on the recogn ition sheet is superio r to 1,200 kg. For the cars under 1,200 kg the w indscreen hoop is not com puisory. The general design ing m ust com ply w ith draw ings 6 and 7.

The safety ro li-ba r o r cage m ust be conceived in such a way as not to obstruct the access o f the fro n t seats and not to encroach on the space provided fo r the driver and its passenger. On another hand, it is a llowed th a t the elem ents of the ro ll-ba r o r cage encroach on the space o f the rear passengers, and pass th rough the upho ls te ry o r the rear seat(s).

The main ro ii-ba r hoop(s) m ust be placed as near as poss ib le to the roo f in o rder to lim it its c rushing in the event o f a som ersault.A ttac h m e n t o f s a fe ty ro il-bars on th e chassis

The attachm ent po in ts o f the s tru ts o f the main ro ll-b a r hoop(s) on the chassis m ust be loca lly re in forced by means o f a s tee l-p ia te—2 mm th ick at least— welded on the shell, w ith a pro longa tion along a vertical m em ber o f the chassis (fo r exam ple; door p illa r— see draw ing 8). The to ta l surface o f th is plate m ust be of 35 sq cm at least, o f w hich a th ird at least ensures the connecting w ith the vertical chassis-m em ber. The fix ing o f the main ro ll-b a r hoop(s) m ust be realized w ith at least 3 bo lts and nuts— diam eter: a t least 8 mm— w ith hexagonal head. The attachm ent plate integrated to the ro il-b a r s tru ts shall have the same th ickness as the wail o f the tube on w hich it is fixed.

W hen the ro li-b a r rests on a box-m em ber, the la tte r m ust be loca lly re in forced by a s truc tu re constitu ted of e ithe r welded bolts o r w elded tub ing ends (see d raw ing 9).R em ovab le connections

In case rem ovable connections are used in the ro ll-ba r construc tion , they m ust com ply w ith a type approved by the FIA .

A re approved up to now : a tapered connection and a tw in lug connection w ith axis w orking under double shearing cond itions and a m uff-connection com plying w ith d raw ings 10, 11 and 12.

The tw in lug connection may however be used o n iy fo r long itud ina l brace-rods and not fo r the basic fram e o f the ro ll-bar(s).W a iv e r

if, ow ing to the orig ina l conception o f the car, it is no t possib le to f it a satety ro ll- bar w ith the regu lar im planta tion and structure, the m anufacturer may ind icate a varian t on the recogn ition sheet and subm it it to the CSI fo r approval.O pen Cars

C onception and realization identica l to those prescribed fo r closed cars. M oreover, the main hoop behind the fro n t seats m ust be sym m etrical about the leng th w ise centre-line o f the car and com ply w ith the fo llow ing figu res (see d raw ing 14);

H e ig h t: the top o f the ro li-ba r m ust be at least 5 cm s (2") over the helm et of the driver norm ally sat a t h is wheel.

W id th : measured on the inside of the vertical s tru ts o f the ro li-b a r; there must be at least 20 cm s (8") measured at 60 cm s (23") above the driver's and passenger’s seats (on the line pe rpend icu ia rto the d rive r's vertebrae from the leng th w ise centre-line to the outside).

125

L e n g th w is e lo c a t io n : the lengthw ise d istance between the top of the ro i!-bar and the helm et o f the driver norm ally s ittin g at h is steering wheel m ust not exceed 25 cm.

W ill a lso be considered as open cars, cars w hich have no s truc tu ra l parts between the upper part o f the w indsh ie ld fram ework and th a t o f the rear w indow , i f any.

R oll-bars :G eneral considerations

1 — The basic purpose of such devices is to p rotect the driver if the c a rtu rn s over or is involved In a serious accident. T h is purpose shou ld always be borne In mind.

2 — W henever bo lts and nuts are used, they shou ld be o f a su ffic ien t m inim um\T7

diam eter, accord ing to the num ber used. They shou ld be o f the h ighest poss ib le qua lity (preferably a ircra ft). Square head bo lts and nuts shou ld n o t be used.

3 — One continuous length o f tu b in g shou ld be used fo r the main s tructu re w ith sm ooth co n tinuous bends and no evidence o f c rim p ing o r wall fa ilu re .

4 — A ll weld ing shou ld be o f the h ighest poss ib le qua lity w ith fu ll penetration (p referab ly arc w eld ing and in particu la r heiiarc). A lth o ug h good outs ide appearance o f a weld does no t necessarily guarantee its quality, poor look ing w elds are never a s ign o f good workm anship.

5 — Braces shou ld preferably be o f the sam e size tub ing as used fo r the main structure.

6— For space-fram e cons truc tions it is im portan t tha t crash-bar s tructu res are attached to cars in such a way as to spread the loads over a w ide area. It Is not su ffic ien t to s im p ly attach the ro ll-b a r to a sing le tube or ju n c tio n o f tubes. The ro il-ba r shou ld be designed in such a way as to be an extension o f the fram e itse lf, no t s im ply an attachm ent to the fram e.

C onsiderable care shou ld be attached to the necessary streng then ing o f the basic structure, fo r instance by adding re in fo rcem ent bars o r p lates so as to properly d is tribu te the loads.

7— For m onocoque construc tions , conside ra tion shou ld be given to using a ro ll-b a r hoop o f 360 degrees com plete ly around the ins ide o f the car, and attached w ith su itab le m ounting plates. Th is type o f ro li-ba r then becom es a su bstitu te fo r the fram e.

D im e n s io n s : the d im ensions o f the ro li-bars m ust be as fo llo w s : the m inim um heigh t m ust be at least 36 inches (92 cm) m easured along the line o f the d rive r's spine, from the metal seat to the top o f the ro li-bar. The to p o f the ro il-b a r m ust also be at least a t 5 cm above the drive r’s helmet, when the drive r is s itting in norm al d riv ing position .

The w id th m ust be at least 38 cm measured ins ide the ro il-b a r between the tw o vertical p illars o f the sides. It m ust be m easured at 60 cm above the metal seat on the perpendicu la r to the line o f the d rive r's spine.

S tre n g th : in o rder to obtain a su ffic ien t s treng th fo r the ro li-ba r, tw o poss ib ilities are le ft to the m anufacturers;

a) the w eigh t being th a t o f the car In s ta rting order (d river aboard, fu ll tanks), the ro il-ba r m ust be able to w iths tand th ree sim ultaneously applied loads: — 1.5 G lateral,— 5.5 G fo re and a ft— 7.5 G vertical, the Induced loads being carried over In to the prim ary

s tructure .A ce rtifica te signed by a qua lified techn ic ian m ust be subm itted to the

S cru tineers o f an event. It m ust be accom panied by a draw ing o r a pho to graph o f the said ro ll-ba r and state th a t th is ro ll-b a r can w ithstand the above m entioned loads.

b) the tubes and brace(s) m ust have a d iam eter o f at least I f Inch (3.5 cm ) and a t least 0.090 inch (2 mm) wall th ickness. The m aterial shou ld be m olybdenum chrom ium S A E 4130 or S A E 4125 (o r equ iva len t In D IN , NF, etc.).

There m ust be at least one brace from the top o f the bar rearwards at an angle no t exceeding 60° w ith the horizonta l. The d iam eter and m ateria l o f the brace m ust be the same as those o f the ro il-bar Itself.

In the case o f tw o braces, the d iam eter o f each o f them may be reduced to 20/26 mm.

179

Removable connections between the main hoop and the brace m ust com ply w ith d raw ings nos 10 and 11 o f A rt. 253 o r w ith any o ther type approved by the FIA.

N B : A s an ind ica tion , the fo iiow ing advice is given fo r the w eld ing o f steel S AE4125 (25 CD 4, etc.).

T h is steel can be welded by oxy-acetylene. The w e id ing -rod m ust be in A 50 steel (French aeronautica l spec ifica tion , A IR 9114 regu la tion) when no therm al treatm ent is carried ou t a fter weld ing.

A s regards e lectric arc-w e ld ing w ith coated e lectrodes, i t is necessary to use e lectrodes o f the basic type having been previously k iln -dried at 350°C (682°F) during tw o hours.

The metai deposited by these e lectrodes may be e ithe r in carbon steel w ith su ffic ien t characteris tics (fo r example, e lectrode E444B o f the French norm A81309— o f the B ritish norm 639-1719— o f the A m erican w eld ing norm A23364- E60/E70) o r in steel o f the 25 CD4 type (e lectrode com plying w ith the aeronautica l spec ifica tion A IR 9114; e lectrode A IR 85; R = 75 , E=60, A = 1 3 % ; resilience;107,000 ps i; lim its o f e las tic ity ; 85500 m in im um ; e longation ; 13%— basic).

In a il cases, the operators m ust be previously qua lified and the post welding contro l shou ld be carried ou t by dye penetrant testing or magnetoscopy.

C ab les , lines and e lec trica l eq u ip m en t: except if the cables, lines and e lectrica l equ ipm ent such as battery, fue l pum p, etc., are in com pliance w ith the requ irem ents of the a irc ra ft industry as regards th e ir loca tion , m ateria l and connections, they m ust be placed or fitted In such a way th a t any leakage cannot resu lt in ;

— accum ula tion o f liqu id ,— entry o f liqu id in to the cockpit,— con tac t between liqu id and any e lectrica l line o r equipm ent.Should the cables, lines or e lectrica l equ ipm ent pass th rough or be fitted in

the cockpit, they m ust be fu lly enclosed in a cover o f a liq u id -tig h t and fire -p ro o f material.

S a fe ty fue l ta n k s : Cars o f the In te rnationa l Form ulae 1,2 and 3 m ust be fitted w ith safety fue l tanks com plying w ith one o f the three sets o f sp ec ifica tions given hereafter. A rt. 297.

Besides, fue l tanks m ust be filled w ith safety foam com ply ing w ith the A m e rican m ilita ry spec ifica tions Mil-B.83054— (B affle m aterial).

T a n k fillers and caps: it is recalled th a t on fo rm u la cars, the tank fille rs and th e ir caps m ust not p rotrude beyond the coachwork.

The caps m ust be designed in such a way as to ensure an e ffic ien t locking action w hich reduces the risks o f an accidenta l opening fo iiow ing a crash Im pact or incom ple te locking a fte r re fue lling.

The fille rs m ust be placed away from po in ts w hich are vu lnerable in case o f a crash. The a ir vents m ust be located at least 25 cm to the rear o f the cockpit.
