标题: BS1363-1这两段话如何理解？
10.1.1 Compliance shall be checked by inspection and the following:
a) for metal parts insulated from live parts, by the test described in 15.1.3;
b) for metal parts connected to an earthing terminal or earthing plug pin, by the following test.
A current of 25 A ± 0.75 A, derived from an a.c. source having a no-load voltage not exceeding 12 V, is passed for s between the remote end of the protective conductor of a 3-core flexible cord (cut to a length of 150 mm ± 5 mm measured from the nearest edge of the earthing pin) and the remote end of the earthing plug pin and any accessible metal part intended to be earthed, taking account of the following:
1) for non-rewirable plugs, the manufacturer’s connection is tested as supplied, with the flexible cord cut to a length of 150 mm ± 5 mm measured from the nearest edge of the earthing pin, precoiled flexible cords being extended before measurement.
2) for rewirable plugs, 1.25 mm2 flexible cord complying with Table 27 of BS 6500:2000 shall be used:
i) for screw type terminals the clamping screw shall be tightened with a torque equal to two-thirds
of the appropriate value given in Table 3;
ii) for clamp-type (screwless) terminals the connection shall be made in accordance with the
manufacturer’s instructions.
The resistance between the earthing terminal or termination and any other nominated metal part shall not exceed 0.05 欧。

对接地电阻测量，测试部位规定如下：between the remote end of the protective conductor of a 3-core flexible cord (cut to a length of 150 mm ± 5 mm measured from the nearest edge of the earthing pin) and the remote end of the earthing plug pin and any accessible metal part intended to be earthed。
但要求为：The resistance between the earthing terminal or termination and any other nominated metal part shall not exceed 0.05 欧。
问题：两者部位不统一。

12.2 The outline of the plug shall not exceed the dimensions shown in Figure 4a) for a distance of not less than 6.35 mm from the engagement surface and within these dimensions there shall be no axial projection from the engagement surface of the plug, except that at a distance more than 6.35 mm from the engagement surface the outline of the plug may exceed the dimensions shown in Figure 4a) in the plane of the earth pin and in the plane of the cord entry to facilitate the removal of the plug from the socket.。

这部分看过两个翻译稿，觉得都不到位。哪位能给个比较标准的理解？

问题一我的理解:对於插头带3芯有接地线者将其线裁成150mm，在插头的接地PIN与接地芯线末端，施加AC12V以下25A电流60S，其阻抗须在0.05欧姆以下! 其要求所说的就是指提及的插头接地PIN与接地芯线末端金属导体处。

问题二待我找到图面再研究看看...

要求为：The resistance between the earthing terminal or termination and any other nominated metal part shall not exceed 0.05 欧

即接地端子或端头与其它规定为接地部件之间的接地电阻不大于0.05欧姆。这与IEC60884-1一致。

而前面是接地导线最远端与接地插销最远端，及接地导线最远端与其它接地部件。

如果按要求来说，用接地电阻仪的两个夹子一个夹在接地端子或端头上，另一夹子夹住插头接地插销或其它接地金属部件，根本没涉及到接地导线。

原文 :
要求为：The resistance between the earthing terminal or termination and any other nominated metal part shall not exceed 0.05 欧

即接地端子或端头与其它规定为接地部件之间的接地电阻不大于0.05欧姆。这与IEC60884-1一致。

而前面是接地导线最远端与接地插销最远端，及接地导线最远端与其它接地部件。
.......

10.1.1节这段话，应该分成两种情况来谈:

1.插头接地端子的金属末端到接地导线的末端，这是b)项所讲的内容，而其後又有1)、2)的补充条件，要看你实际测试的产品是怎样，依照条件去测试，不是执着在<The resistance between the earthing terminal or termination and any other nominated metal part shall not
exceed 0.05Ω >这段话!! 不同的产品可能会有不同的加工部件，所以不会刚好只有铜导线，像螺丝、圆盘端子等加工部件就是了，标准只是讲测试原则。只要最终的两端阻抗在0.05Ω 以下就是合格的。

2.for metal parts insulated from live parts, by the test described in 15.1.3
这个测试就要参照Insulation resistance的要求方式去测。

我的理解The resistance between the earthing terminal or termination and any other nominated metal part shall not exceed 0.05 欧，是：接地触头的低电阻测试，并不是整条CORD的电阻测试。
