Standard Specification for Safety and Performance of Fun-Karts
ABSTRACT
This specification deals with the safety performance specifications for commercially manufactured fun-karts intended for private use, on suitable off-road terrain, by consumers, and does not apply to concession, race, home-made, consumer-modified fun-karts, fun-karts that are pedal-powered, unpowered fun-karts, or fun-karts, which are used for commercial purposes. This specification does not cover labeling, maintenance, or use. Materials shall be tested and shall conform to the requirements for fun-kart frame, fun-kart controls, tire capacity, paint, electrical system, fun-kart engines, shields and guards, brush bars, seat belts, fasteners, and plastics.
SCOPE
1.1 This specification relates to the safety performance specifications for commercially manufactured fun-karts intended for private use, on suitable off-road terrain, by consumers.
1.2 This specification is intended to reduce hazards, other than those inherent in the sport of fun-karting, to the users of fun-karts during normal intended use by specifying performance standards of manufacturing.
1.3 This specification applies to fun-karts for private use and does not apply to concession, race, home-made, consumer-modified fun-karts, fun-karts that are pedal-powered, unpowered fun-karts, or fun-karts, which are used for commercial purposes.
1.4 This specification recognizes that there are operational hazards relating to fun-karts, which operators and passengers are deemed to have accepted by their use and operation of the fun-kart including, but not limited to, falling out, running into, through, under or over objects, upsetting the fun-kart, general operator recklessness, pinches, scratches, or bruises, or a combination thereof.
1.5 This specification does not cover labeling, maintenance, or use. For use and maintenance, see Safety Guide F1928.
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
