分析:
) M7 q, O' C: l该产品由公告给出的缺陷很简单,只有一条:实际就是耐潮湿要求中的防溢水不合格。9 p( O6 ~9 t; N& g; K& I& Q1 k( K
产品内部结构,没有图片,无法知道。如果有带电端子在电源进线下放的话,的确溢水试验容易不过。但需要讨论的问题不在此,而在于标准15.2这一条本身,或者说针对这一条如何理解和判定。首先将这一条摘录如下:6 ^. n; ]- r) k* l

15.2 在正常使用中能够承受液体溢出的器具,其结构要能使这种溢出的液体不会影响器具的电气绝缘。

! Q7 Q& i7 L b
/ u* G0 O& U. ?$ Z- _& j# F* Z 现在的问题是:对该条款的符合性是通过如标准所说的“Compliance is checked by the following test通过试验来确定,还是通过试验+分析来确定?
$ y$ Z3 P( K# i- N r& m
. V# ]8 x. U1 x( ^3 e- L0 |- H) v 问题的提出在于本条款的溢水试验在很多情况下会出现随机性,即试验的水量是有限的,每次试验由于器具放置环境(如水平面的偏差,角度的不同),液体注入角度、注入速度等变化,水流溢出的流向可能是随机的;同一型号产品不同的样品,试验的情况也会不同。如本例,如果试验,液体可能会流到带电端子上,但并不是一定会流到带电端子上。甚至在多次试验中,更多次是不会的。就标准从严的角度说,有这种可能就应该视为不合格;但从试验的角度或从发生争议的角度去看,如果试验时前面所预期的可能没有发生(溢出液体并没有流到带电端子上),那该如何看待呢?或者是试验就应当不断重复下去,直到这种可能发生!!

" [8 R6 y5 S* p' {; T5 F4 E! ~
当然如果本例在试验中 溢出液体一定会流到带电端子(the liquid will get onto the live terminals)或出现标准本条规定的不符合,则不存在争议。 |
