Introduction

This document is a type C standard as stated in EN ISO 12100 (all parts)

The kart concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document

When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for karts that have been designed and built according to the provisions of this type C standard

1 Scope

This European Standard is applicable for karts, according to 3.1, that are not intended to be used on public roads

This European Standard applies to:

— leisure karts only;

— karts propelled by a combustion engine, including LPG combustion engines;

— karts used on indoor and outdoor tracks, permanent or temporary;

— karts used on supervised tracks designed for leisure karting, with a sealed ground (such as asphalt, concrete, ice or snow)

This European Standard does not apply to:

— karts used for competition organised by and under the responsibility of the CIK-FIA and/or ASN, ensuring through the granting of licenses by an ASN or one of its affiliated members as defined in the International Sporting code, compliance with the safety, sporting, disciplinary and technical rules of the CIAK-FIA and/

or ASN;

— karts designed exclusively for competition and toys;

— cross country karts;

— 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

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

f) Points 6 and 8: rear of the protection, facing rear bearings

g) Point 7: middle of the protection, rear

Figure 4 — Selected points for measurement of all-around protection - Contact between two karts

The verification shall be in accordance with the following calculation:

— calculate the value CPFij

CPFij = min (bi, bj) – max (ai, aj) where

CPFij = contact protection face of point i with point j

ai= bottom edge height of point i

bj = upper edge height of point j

Min (bi, bj) – lowest value of bi, bj

Max (ai, aj) – highest value of ai, aj

— Then calculate the CPFij values for:

i = 1 to 12 and j = 1 to 12, and find the minimum value of:

CPFij for i = 1 to 12 and j = 1 to 12

The minimum value of CPFij shall not be less than the minimum requirement of 65 mm

The kart shall be equipped with a support for the gas tank (fixed or removable)

The kart shall have a fastening system to secure the gas tank on its support

The gas tank support and fastening system shall prevent movement of the tank in both longitudinal and lateral direction

The gas tank support and retention system shall be designed to withstand acceleration (lateral and longitudinal) of 20 g on the full tank, without plastic deformation

During the test, the LGP tank retention system shall not cause structural damage to the tank

The gas tank support and retention system shall not show plastic deformation during the crash-test of Annex B

The fastening system shall be secured to prevent inadvertent opening under vibration or crash situation

7.13.2.3 Testing method for the LPG tank retention system

The LPG gas tank (reference block) is fitted with devices (welded/straps) to allow the application of a 20 g force in a horizontal and in a longitudinal direction in the mid-plane of the tank

The reference block is installed on the LPG tank retaining system and secured with the fastening system The chassis of the kart is rigidly secured

A load of 20 x (weight of the full tank) is applied in longitudinal and lateral directions

7.13.2.4 Fitting and hoses

Fittings and hoses shall be laid so that they cannot be damage in kart to kart contact or in kart to track contact Fittings and hoses shall be laid so that they cannot be damage by the driver when getting in or out the kart The LPG system shall incorporate a manual shut-off system, an excess pressure flow valve and an automatic filling shut-off system

7.14 Fire – explosion

7.14.1 Fuel system (petrol)

The fuel system shall be fitted in the area protected by the all round protection and shall enable an unhindered filling with an appropriate device e.g funnel

The fuel tank shall either be fitted with a pressure venting device discharging to a safe area or shall have an overflow containment system e.g an overflow tank

The fuel tank capacity shall not exceed 12 l

Instruction for the safe refueling of hot engines shall be given in warnings in the user's manual

7.14.2 Fuel lines

The fuel hoses shall be made with materials the thermal, mechanical and chemical behaviour of which continue to be appropriate under their intended conditions of use

Fuel lines shall be laid so that:

— they do not go under the chassis;

— they cannot be damaged by stepping in or out of the kart;

— they are not exposed to excessive temperatures

7.15 Noise

The karts shall be designed so that hazards by emissions from airborne noise are reduced

The noise emission values of the kart shall be measured according to Annex D (noise emission)

The corresponding results shall be indicated in the instruction handbook (see D.10) and in documents for sales providing performance data of the kart

7.16 Vibrations hazards

Hand-transmitted vibration emission by the karts shall be minimised as far as possible by design of the kart following the principles defined in CR 1030-1

NOTE Vibration is dependent on both on the kart and track conditions/surface

Among the important aspects to be considered during design is the balancing of the moving parts of the engine over the range of engine speed from idling to the maximum achievable in use

The efficiency of the design measures regarding vibration emitted by the kart may be assessed by comparing the vibration emission of the kart, e.g when tested in accordance with Annex E with other karts of the same family and of similar size and power

7.17 Exhaust emissions

The user maintenance guide shall warn operators about the hazard due to gas emission, especially for karts used on indoor tracks

7.18 Starter batteries and batteries for second systems (not propulsion)

Batteries shall be protected against shock arising from contact with other karts or any element of the track Batteries shall be securely retained in the kart (e.g straps)

Batteries shall not be reachable by the driver when in the driving position and shall be covered
