TECHNICAL BULLETIN Rally/Road – National Rally Code REFERENCE: http://docs.cams.com.au/Manual/Rally/RR01-National-RallyCode-2016-1.pdf RATIONALE:
To amend the National Rally Code (NRC) to reflect changes made in Schedule R and Group 3C Production Rally Cars
ACTION: 2. … (i)
Eligibility and Entry
Signs on Cars: Signs and advertising will be allowed on vehicles in accordance with Schedules K (refer “General Requirements for Cars and Drivers” in the CAMS Manual of Motor Sport), unless specifically varied in Supplementary Regulations. The requirements of NCR 155 must be observed. Vehicles must not display competition numbers other than those specified and provided by an event’s organisers. Such numbers must be removed or covered immediately the event is concluded. This shall not apply to cars while they are displayed in showrooms or other trade promotions held away from public roads. The name of each crew member, in accordance with ARC regulations, shall be permissible at all levels of competition with the exception of those comprising part of an FIA Championship, where regulations may conflict. For international events the requirements shall be that of the relevant FIA regulations, or where silent, in accordance with these regulations. In all other rallies, such display is optional unless required by the applicable supplementary or sporting regulations, but if used shall comply with this Regulation. The names shall be placed toward the bottom of the rear window, each centered in the window space and to each name, with minimum 30mm separating the upper case letters of the two names and the lower edge of the window frame. The driver name shall be displayed above the codriver’s name on both sides of the car. The letters shall be of uniform style, white in colour and without background, using a capital for the first letter of the name, and lower case for all the other letters (see Figure K-3 of Schedule K – refer to “General Requirements for Cars and Drivers” in the CAMS Manual of Motor Sport). The typestyle shall be “Helvetica Bold”, “Zurich Bold” or Ärial Bold”. The same font size shall be used for each letter. Each upper case letter shall be 100mm except in the case of the codriver, where the upper case letters of the co-driver name may alternatively be 80mm high. For grammatical correctness other letters of the surname may use a capital letter (eg, MacDonald). Where there is insufficient space or no window to display the name/s in accordance with this regulation, the following shall apply; a.
The minimum reduction in size to fit the name shall be permitted, and both names shall be displayed in lettering of the revised size, in one of the approved fonts. An abbreviation of the name, in question may be permitted, subject to CAMS approval.
The turret/door frame immediately above the side glass line or front guard may be used for the name of the crew member seated on that side of the vehicle. In such cases the names shall be displayed in accordance with this regulation save that the letters shall be displayed on a black background.
NATIONAL RALLY CODE APPENDIX F – General Requirements Muffler: An effective exhaust muffler must be fitted at all times. The maximum noise emission permissible is 96 dB(A) as tested by the CAMS method. Reflective Triangles: At least two reflective or fluorescent red triangles of metal or plastic material (sides at least 350mm in length) must be carried, and must be displayed in cases where a stationary car could be a hazard to other road users (eg, breakdown). SOS/OK Signs: Each car is to carry at least one ‘OK/SOS’ sign. ‘OK’ shall be green or black, and ‘SOS’ shall be red. The sign may incorporate reflective materials. Supplementary Regulations are to specify whether the organiser will supply a sign in the roadbook, or as a separate rigid sign, or if each crew is to supply its own rigid sign. If a sign is supplied in the roadbook, the back cover of the roadbook or route instructions shall be printed on one side with ‘OK’ and ‘SOS’ on the other side, and printed on card (min. 130gsm). The background must be at least A4 size (297mm x 210mm). For all Australian Rally Championship and National-level Tarmac Rally events the sign background must be A3 size (420mm x 297mm). The sign may be folded to fit within the A5 format (148mm x 210mm) of the roadbook or route instructions. Road signs shall be on a mounting sheet of area at least 620cm2 and the letters shall be clearly discernable and fit for the purpose. Such signs may be mounted on to rectangular or triangular self-supporting brackets. Where the crew is to supply the sign, it shall be presented at scrutiny. First Aid Kit: All vehicles are required to carry on board a weatherproof emergency first aid kit, which can be easily accessed, containing at least the following: 2 x extra large universal accident dressings 2 x large open weave bandages 2 x medium open weave bandages 1 x pair dressing scissors 1 x roll adhesive tape 6 x safety pins 1 x large burn dressing with a non-adhesive surface 1 x thermo accident blanket 2 x medium combination pads 6 x adhesive plaster strips 1 x triangular bandage 2 x sterile eye pads 1 x first aid manual
Notes: 1 2
These items may be purchased from St John Ambulance as a kit or from any reputable first aid supply company. This kit is no substitute for first aid training. It is recommended that all competitors should undertake a first aid training course.
Mud Flaps, sill and underbody protection: Notwithstanding any Group or Category regulation providing specific requirements on the subject of coachwork and underbody protection, it is permitted to add material to the vehicle solely for protection from stone chip damage: Mud flaps of stout material shall be fitted behind all driving wheels, and in the case of front wheel drive vehicles, behind all four wheels. They shall be no closer than 50mm to, and no further than 100mm from, the ground, shall mask the full width of the tyre when viewed from behind, and be within 300mm of the tyre. Mud flaps fitted behind wheels shall leave un-masked at least one-third of the width of the car. Those fitted in front of the rear wheels shall leave at least 20cm un-masked. The vehicle shall comply with these requirements when it is presented in “ready to start” condition. Where material is added to the sill and/or side of the vehicle it shall follow the contours of the existing body work. Material is free with the following restrictions: • pliable material maximum thickness of 6mm; eg, polyurethane, rubber or similar; • solid material maximum thickness of 3mm; eg, aluminium, Kevlar®/carbon/fibreglass. Where material is added to the underside of the vehicle it shall only be to the perimeter of the vehicle between the rear of the front arch and the front of the rear arch and shall be solely for the purpose of deflecting stones that may cause damage to the vehicle. The material SHALL be pliable, eg, polyurethane, rubber or similar, with a maximum thickness of 6mm and may not protrude further than the plan view of the vehicle or 100mm from the sill, whichever is the lesser. Towing/de-hitching Gear: Other than in introductory rallies, cars must be fitted with towing points complying with the following: • have an internal diameter of at least 40mm; • are fitted forward of the front axle and rearwards of the rear axle; • are clearly visible in yellow, orange or red, the chosen colour being in contrast to the colour of the body work immediately adjacent the towing point; • are constructed and fitted in such a way that when a load is applied to the towing point, parallel to the ground and in a direction facing away from the vehicle, parallel to the longitudinal centre line of the vehicle, the vehicle shall be capable of drawing the car over two blocks of 100mm height. These blocks shall be of a section 100mm x 200mm, not less than the width of the tyre and shall be placed immediately “in front” of the tyres closest to the towing point being subject to the applied load. In order to test the strength of the towing point, any non-structural body work which interferes with the test may be removed. OR As an alternative to the above, tow hooks provided by the manufacturer of the car as a standard fitment may be utilised, provided they are easily accessible and clearly visible, in yellow, orange or red, contrasting with the colour of the bodywork immediately adjacent to the towing point, and pass the same test as outlined above. It is recommended that towing and de-hitching gear also be fitted to vehicles competing in introductory rallies. Tyres: The use of studded or spiked tyres is prohibited. All tyres shall be treaded in the original manufacturing process to a minimum depth of 2mm. Tyres used shall not be expressly designed for use on motor racing circuits (eg, slicks). Special requirements for Australian Rally Championship, International and Special stage rallies: Fuel: An adequate firewall to separate the fuel tank from the habitacle which is impervious to the passage of fumes or liquids, must be fitted to all cars which are fitted with other than their standard fuel tank systems. Fuel lines, lubricating oil lines and lines containing hydraulic fluid under pressure – Specifications and installation Application: all vehicles shall comply. The original series production fittings and lines may be retained. If the series production fittings and lines are not retained and where line replacement is permitted by relevant Group regulations, the following regulations shall apply. Lines which carry hydraulic fluid, fuel or lubricating oil may pass through the cockpit.
Any line containing fuel or lubricating oil shall not incorporate any connectors inside the cockpit except at the front and rear bulkheads in accordance with Drawings 253-59 or 253-60. All fittings and lines used for the passage of fuel, lubricating oil and hydraulic fluid under pressure shall be manufactured according to the specifications below: • when flexible, these lines must have threaded, crimped or self-sealing connectors and an outer braid resistant to abrasion and flame (will not sustain combustion); • the minimum burst pressure measured at the noted minimum operating temperature shall be: Fuel lines (except the connections to the injectors and the cooling radiator on the circuit returning to the tank including any cooling radiator or lines): Lubricating oil lines: Lines containing hydraulic fluid under pressure:
70 bar (1000 psi) at 135°C (250°F) 70 bar (1000 psi) at 232°C (450°F) 280 bar (4000 psi) at 232°C (450°F)
Notwithstanding the requirements detailed above, if the operating pressure of any hydraulic system is greater than 140 bar (2000 psi), the burst pressure shall be at least double the operating pressure. Note: Steel ‘bundy’ tube which is designed for use in automotive applications will usually comply with the minimum burst pressure as will many flexible braided lines designed for fuel injection systems. Reputable hose and line suppliers or manufacturers will be able to provide specifications and documentation (eg, a catalogue) that can assist the scrutiny process.
