7.3 Protection against mechanical hazards
7.3.1 Kart protection
7.3.1.1 General requirements for all-around protection
All around protection shall be provided that:
— prevents wheel to kart contact and, therefore, the launching effect,
— ensures impact stability, e.g. reduces the risk of karts climbing one on the other, of karts rolling
over, of karts going under track protection,
— reduces the effect of impact loads on the driver,
— reduces the effects of impact loads on the frame and components.
The relevant dimensions of the protection are described in Figure 2 and the requirements are specified
in Table 4.

c depth of the all around protection
Figure 2 — Dimensions of the all around protection
The dimensions a, b and c of the all-around protection shall be in accordance with the values given at
Table 4 at all positions around the kart.
Compliance with Table 4 shall be verified, as a minimum, by the measurement of the dimensions a, b
and c at the 12 positions defined in Figure 4.
NOTE Table 4 can only be applied directly to all around protection having a flat vertical contact surface.
See 7.3.1.2 for other contact surfaces.
7.3.1.2 Additional requirements for all-around protection having a shaped surface
When the vertical surface of the protection is shaped, the dimensions a, b and c shall be measured using
the tool described in Figure 3. The tool shall be applied until the vertical component of the tool (1)
makes contact with the outermost point of the all-around protection before adjusting the two
measuring arms (3) and (2) until they make contact with the protection; the values of a, b and c shall be
determined with the two measuring arms (3) and (2) in these positions in accordance with Figure 3.

protection systems, regardless of the direction of contact between two karts of the same type, shall
correspond over a minimum vertical distance of 65 mm, the kart being on a level surface with no
steering input. As a minimum, this requirement shall be verified by measurement at the 12 positions on
the all-around protection indicated at Figure 4 for each of the two karts of the same type.
NOTE The checking of the correspondence of the contact areas at the combinations arising from the 12
measurement positions on each kart involves the consideration of 144 combinations of contact between the two
karts. For example, Figure 4 illustrates 1 of the 144 combinations where position 11 of kart A contacts position 2
of kart B.

The REESS shall be encapsuled by the all-around protection
7.3.1.6 Energy absorption systems
All karts shall be provided with frontal, side and rear absorption energy systems in accordance with
Annex B.
Energy absorption systems shall be able to maintain their absorption properties under repeated low
speed impacts.
In order to verify that absorption properties are adequate and maintained after recurring impacts, the
crash test according to Annex B shall be repeated four times for each direction of impact. The resultant
acceleration measured on the kart shall not exceed the following upper limits for all the impact events.
a) For Kart type A2, B, C1:
1) Frontal crash maximum acceleration allowed: 15 g
2) Left and right side crash maximum acceleration allowed: 15 g

2) Left and right side crash maximum acceleration allowed: 20 g
3) Rear crash maximum acceleration allowed: 20 g
The result of the first crash test and the fourth crash test and the state of compliance shall be recorded
for every direction of impact.
There shall be no fractures in the elements constituting the kart protection system.
7.3.2 Seat
Karts shall be designed to accommodate the range of intended drivers in accordance with Table 1. This
can be achieved by supplying inserts to modify the size and shape of the seat.
The dimensions of the seat, if appropriate with a suitable insert fitted, shall provide a distance between
the top of the seat and the position of the bottom of the driver's neck in accordance with the following:
a) Kart Type A1: 100 mm ± 25 mm,
b) Kart Type A2: 100 mm ± 25 mm,
c) Kart Type B, C1 and C2:

2) driver height 1 750 mm to 1 950 mm: 200 mm ± 35 mm.
This document only covers low backed seats where the seat back is sufficiently below the driver's neck
(not touching the neck) to allow flexibility of the spine. Higher backed seats are permitted if a risk
assessment has been performed.
7.3.3 Brake system performance
7.3.3.1 General
Karts shall be equipped with a brake system the function of which is to effectively reduce the speed of
the kart when driving in order to minimise the following risks:
— risk of contacts between karts moving at different speeds;
— risk of impacting the track protections at high speeds;
— risk of losing control of the kart speed in general.
The electric kart shall at least fulfil the requirements of 7.3.3.2 and 7.3.3.3 for mechanical brake without
regenerative braking involved.
7.3.3.2 Karts type A1 and A2
When tested in accordance with the static test described in C.1 the brakes of types A1 and A2 karts shall
resist, without any turning of the brake tester, a braking torque of at least 100 Nm with a foot control
force of 300 N applied.
7.3.3.3 Karts type B, C1 and C2
When tested in accordance with the dynamic test described in C.1.6 (dry stop test) karts of types B, C1
and C2 shall reach a mean fully developed deceleration (MFDD) of at least 3 m/s .
When tested in accordance with the dynamic test described in C.1.7 (heat fade test) karts of types B, C1
and C2 shall reach a residual performance (Pr) of at least 60 %.
When a kart manufacturer is fitting the same brake system (at least the control, the transmission
cable(s), the actuator(s) and the brake linings shall not differ) to different kart types and models of an
identified family, it is not necessary to repeat the dynamic tests provided that the following conditions
have been met:
— the dynamic tests have been performed on the heaviest kart type/model;
— the dynamic tests have been performed on the fastest kart type/model.
7.3.3.4 Regenerative breaking
If regenerative breaking is used for the kart, the following requirements are applicable:
— The mechanical braking system shall be the primary brake system and meet the requirements of
this document.
— The level of regenerative braking shall not be controllable by the user.
— The amount of braking force provided by regenerative braking shall not vary for any external
reason, such as but not limited to:
— the state of charge of the battery,
— the temperature of the battery,
— the temperature of the motor,
— the temperature of the controller
so that level of deceleration behaviour of any regenerative braking is constant and predictable.
7.4 Protection against failure of control systems
7.4.1 Brake system control
7.4.1.1 General
Karts shall have, at least, one brake system acting on both wheels of the rear axle. Where the rear axle is
split, or a differential is fitted, the brake system shall provide a separate brake for each rear wheel.
The elements of the brake system shall be protected against self loosening.
All necessary instructions for a proper maintenance of the brake system and of the relevant controls
shall be given in the user maintenance guide described in 9.2.
7.4.1.2 Mechanical components of the brake system
The brake pedal shall be connected at two points to the chassis or any adjustable brake mechanism.
In the case of a mechanical brake, there shall be two brake cables both connected independently. Both
cables shall withstand the braking load individually.
In the case of a hydraulic system, the activation linkage between the brake pedal and the master
cylinder shall have a secondary safety device that ensures brake activation should the primary system
fail.
Control cables shall be fitted to the kart so as to prevent unintentional activation and damage. Cables
shall be installed such that loops, unintended pulling by feet or hands and mechanical damage is
prevented when either driving or getting into and off the kart (e.g. use of conduits, fixing to the
structure to retain in position).
Screw thread ends of brake linkages shall be rolled.
