20.101 appliances shall be constructed so that inadvertent operation is unlikely.
compliance is checked by inspection and by applying a cylindrical rod, having a diameter of 40mm and a hemispherical end, to the switch.
the appliance shall not operate.
回答如下,
1.在没有破坏产品的情况下,尽可能使得开关动作
2.那个条款中有个note: the requirement is considered to be met if a biased-off switch is used. 这里biased-off switch (美标叫maintenance switch)是指那些手握住是联通状态,松开就断开的.一般叫点动开关. 还有把开关装在凹陷口一般也可以通过测试
3.给一段关于标准的解释,你看看就明白了:it is applicable only on pressurized steam cleaner to avoid sudden jet of steam. It is not applicable on instantaneous steam cleaner as defined in the note of sub-clause 22.7.
