分析:
. R/ e: H B( l3 e* s. m* C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。
3 M0 S O- g# l9 Y3 H4 t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:( s$ m. j0 ^3 }

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。
4 z4 S% n( e0 U9 j* g0 U! U% F通过下述试验确定其是否合格。: o2 C/ V( R! S' j5 e" {
带X 型连接的器具,除带有专门制备软线的器具外,其他都应装有表13中规定的最小横截面积允许的最轻型柔性软线。; n" E5 p. M+ n, ~# S5 Q% P
带有器具输人插口的器具,可将相配用的连接器插装到位,或不插装连接器进行试验,两者中取最不利者。 }& m! A' U( W5 k4 ~
取下器具上的可拆卸部件。3 D' T( z( m" M
将器具的液体容器用约含1%氯化钠(NaC1)的水溶液充满,然后,再用等于容器容量的15%,或是0.2 5L 同浓度多余1%氯化钠(NaCl)水溶液,两者中取量多者,在1min时间内持续地注人容器。 W; Y1 h' T9 g) e8 o# q2 \
然后,器具应经受16.3 的电气强度试验,并且视检应表明在绝缘上没有能导致爬电距离和电气间隙降低到低于第29章中规定限值的水迹。

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?
% d, |$ Y$ C+ f% x, _
( v% h, {% S6 o" M1 o4 G 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!
! {# }6 ?6 h6 d1 H
+ `" E: I& m9 A- C 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。 |
