疑问:1 个人觉得应该要有个力度要求吧!
2 一般器具的开关都满足不了这个条款吧. 莫非要锁位开关?
3 这个条款的意义是考虑器具稳定性不够,以至倒地触发器具工作吗?作者: oahemr 时间: 2011-12-22 17:45
没处理过这个标准,刚刚仔细的核对了EN 60335-1,EN 61032 ,EN60335-2-54 个人认为应该有个力度的要求,EN 60335-1 clause 20.2中有提到不超过5N,但是EN 61032中的test probe又不符合EN 60335-2-54 所描述直径40mm的要求.作者: 网络营销bc 时间: 2011-12-22 17:45
看过几份不同机构的报告
判断也是不尽一样
因为一般的器具用的开关基本不可能满足要求. 所以对这条的意义不是很理解!作者: zjh407 时间: 2011-12-22 17:45
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.作者: 网络营销bc 时间: 2011-12-22 17:46
