BS1363-1 接地电阻测量疑问

BS1363-1 12.9.5.2章节第4段落有说到插拔测试后要测量插销和插套之间的接地电阻.
我的问题是; 这个章节的插地销是ISOD类型的.定义在3.23章节有,其中有句话是这样的;.......made of insulating material having........
既然是绝缘的地销,那如何测量它们之间的电阻,只有金属才能测试呀.比如 12.9.5.1章节..
关于IOSD的问题,论坛以前也有讨论过.http://bbs.angui.org/forum.php?m ... 2397&highlight=isod
第一次看这个BS标准,觉得有点吃力,大家请多给意见,不胜感激!

我也看了很久，想不明白。大家快来讨论啊！

12.9.5.1章节有谈到电阻吗？

12.9.5.1章节有谈到电阻吗？

Refer to 12.9.5.2 (for ISOD)

12.9.5.2 Compliance shall be checked by the following.

.....

After 5 000 insertions and withdrawals the standard rewirable plug used prior to the test, for each type of socket-outlet shall be reinserted and the earth resistance test repeated. After the test the earth resistance between the earthing plug pin and the earthing socket contact of the socket-outlets shall be in accordance with BS 1363-2:1995, 10.2.1b).


BS 1363-2:1995, 10.2.1b) 就是要测试 earthing socket pin 与 earthing plug pin 之间之 contact resistance

据本人理解, 完成 “insert” and “withdrawn” test 后, 不应用经过测试后之 ISOD plug 去做 earth resistance test (BS 1363-2, 10.2.1B), 应用 “standard rewirable plug used prior to the test”, 即 “three different makes of rewirable plugs”

12.9.5.2 Compliance shall be checked by the following:

Using a selection of three different makes of rewireable plugs conforming to this standard and three different makes of unswitched socket-outlets conforming to BS 1363-2, selected to represent different earth contact designs, the earth resistance between the earthing plug pin and earthing socket contact of the socket-outlets shall be established in accordance with BS 1363-2, 10.2.1b).

All socket outlet shall be of the type where the earth pin or ISOD of a plug inserted into the socket-outlet operates the shutter mechanism.......

如果你们是ISOD也就是说是两芯的，肯定不用做这个测试了。

你的提醒让我有一种豁然开朗的感觉,其实标准上已经写得很清楚了,只怪我自己没有用心去看.

试验精神是当进行拔插耐久试验后, ISOD plug 会不会破坏普通插座原有特性, 特别是接地片之导电性能!

意思是接地地阻是考虑测试完成后，插座的接地可靠性。也就是说检被测试插头对插座的影响？
