If a requirement indicates that 8.3 (torque test) and 8.4 (tension test) shall be performed, the tension test shall follow after the torque test and be performed on the same component of the toy. 看这句话的意思是,如果扭力和拉力都要做,则拉力要在扭力后的同一个部件上,这和ASTM F963一致。 y3 s- w' [% t+ n& G& `) m$ q; Z

If the component to be tested cannot be gripped between thumb and forefinger, establish whether it is grippable by inserting the feeler gauge between the component and the underlying layer or body of the toy at an angle between 0° and 10° from the toy surface using a force of (10 ± 1) N. If the gauge can be inserted more than 2 mm, the component shall be considered as grippable. 这种情况说的是突出物为半球形或锥形状,首先承认无法被抓紧,从而无法施加扭力;但如果用触规判断突出物与body之间留有间隙则可被抓住,从而可以拉力测试;) T( T9 z7 w$ G
