Scope适用范围： Fixings, the failure of which may impair compliance with this standard and electrical connections shall withstand the mechanical stresses occurring during play. (*17.1*) 其失效可能有损于本标准符合性的固定连接和电气连接，应承受玩具在使用过程所产生的机械应力. For screws and nuts using for electrical connections or which are likely to be tightened by the users. (*17.1*) 用于电气连接的或可能被用户自己上紧的螺钉和螺母。 Note 1: Regarding to the screws and nuts which are likely to be tightened, screws for enclosure integrity would not be tested as the enclosure is not intended to be disassembled. However, screws for battery compartment cover would be tested. 注 1: 对于可能被上紧的螺钉和螺母，用于不被拆开的整体外壳的螺钉不进行测试。 但是，用于固定电池室盖的螺钉须进行此项测试。 Note 2: For those screws inside the toy, they would not be tested if the purpose of the screw are not for transmitting pressure. 注2: 用于玩具内部的螺钉,如果它们不用作传递压力可不做测试。 Electrical connections carrying a current exceeding 0.5A. (*17.2*) 承载的电流超过0.5A的电气连接. Equipment测试设备: Torque Drivers扭矩螺丝刀 Multimeter万用表 Vernier caliper游标卡尺 Procedure程序: Test Procedures测试程序: Check (by inspection) if the screws and connections consists of features which impair compliance with this standards. (*17.1*) 检查(通过目视)螺钉连接失效是否有损于本标准的符合性. For screws and nuts using for electrical connections (pressure to ensure the mechanical contact of current carrying parts) or which are likely to be tightened by the users are tested as follows: (*17.1*) 用于电气连接的(确保载流部件紧密接触)或可能由用户自行上紧的螺钉和螺母应做以下测试: The screws or nuts are tightened and loosened as follows: (*17.1*) 螺钉和螺母应按以下拧紧和拧松: 10 times for screws in engagement with a thread of insulating material. 旋进绝缘材料的螺钉应进行10次测试。 5 times for nuts and other screws (such as screws in engagement with a thread of metal). 螺母和其它的螺钉5次测试(例如：旋进金属的螺钉)。 Screws in engagement with a thread of insulating material are completely removed and re-inserted each time. (*17.1*) 旋进绝缘材料的螺钉每次应完全拧出,然后重新插入. The test is made by a suitable screwdriver, spanner or key and by applying a torque as shown i
