Scope1.1 This specification relates to the safety performancespecifications for commercially manufactured fun-karts in-tended for private

3、use, on suitable off-road terrain, by consum-ers.1.2 This specification is intended to reduce hazards, otherthan those inherent in the sport of fun-karting, to the users offun-karts during normal intended use by specifying perfor-mance standards of manufacturing.1.3 This specification applies to fun

4、-karts for private useand does not apply to concession, race, home-made, consumer-modified fun-karts, fun-karts that are pedal-powered, unpow-ered fun-karts, or fun-karts, which are used for commercialpurposes.1.4 This specification recognizes that there are operationalhazards relating to fun-karts,

5、 which operators and passengersare deemed to have accepted by their use and operation of thefun-kart including, but not limited to, falling out, running into,through, under or over objects, upsetting the fun-kart, generaloperator recklessness, pinches, scratches, or bruises, or acombination thereof.
