灯具标准理解问题

灯具中接地电阻测试，接地线是否考虑进去，不考虑是不是接地线要单独测试一次，在减去了（通常为了方便测试，将接地线一起测了

coast

不知道欧规标准是如何要求的，我们有一款轨道灯在按照UL1574标准测试时，连同电线一起测量接地电阻，之后减去电线的电阻，就是灯具的电阻。

也就是接地线再重新测一次，将总电阻减去就行，使吧

60598里的规定：

A current of at least 10 A, derived from a source with a no-load voltage not exceeding 12 V,
shall be passed between the earthing terminal or earthing contact and each of the accessible
metal parts in turn.

The voltage drop between the earthing terminal or earthing contact and the accessible metal
part shall be measured and the resistance calculated from the current and the voltage drop. In
no case shall the resistance exceed 0,5 Ω. When type testing, the current shall be applied for a
period of at least 1 min.

NOTE ：In the case of a luminaire with a non-detachable flexible cable for the supply connection, the earthingcontact is at the plug or supply end of the flexible cable or cord.

国标里的翻译是：
注：用不可拆卸软缆连接电源的灯具，接地触点是在插头上或者在软缆或软线的电源端的。

我们每次都是把接地线电阻算在里边！莫有减过。。
