一切以标准说话。( T. E1 b- s' V: X
cl 26.1 However, earthing terminals may be accessible if a tool is required to make the connections and means are provided to clamp the wire independently from its connection.$ v( M, N N9 j$ S5 Q' V8 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。* s4 Q/ j% ~! k! ^; R# N) Q
并没有说一定要用特殊的螺钉。: m* ^7 X6 Q9 L. C
cl 27.2 The clamping means of earthing terminals shall be adequately secured against accidental loosing.

7 R7 `) j- Y, s8 p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。 |
