一切以标准说话。; v% P; V8 T0 L5 R

这里讲的是:接地螺钉可露在外面,但连接时需要有工具,并且需要有独*立的措施来夹紧螺钉。此紧固措施可以是弹簧或梅花介子。! _% _; x( ?" @7 h2 m" y3 b* L
并没有说一定要用特殊的螺钉。: K/ \# _8 R k% ~; b+ b
cl 27.2 The clamping means of earthing terminals shall be adequately secured against accidental loosing.

所以我们要弄清“及格”和“优秀”的关系:器具的接地措施本来是可接受的,也就是说合乎标准了。你一定要厂家做到“优秀”,如果是建议厂家提高器具质量的角度来说是可理解的。但如果厂家做的器具合乎标准,你任是说人家不合格。这是不可取的。 |
