EN60204-1的接地电阻值没有明确规定，是否能按0.1欧姆？

Test 1 – Verification of the continuity of the protective bonding circuit
The resistance of each protective bonding circuit between the PE terminal (see 5.2 and
Figure 3) and relevant points that are part of each protective bonding circuit shall be
measured with a current between at least 0,2 A and approximately 10 A derived from an
electrically separated supply source (for example SELV, see 413.1 of IEC 60364-4-41)
having a maximum no-load voltage of 24 V a.c. or d.c.. It is recommended not to use a PELV
supply since such supplies can produce misleading results in this test. The resistance
measured shall be in the expected range according to the length, the cross sectional area
and the material of the related protective bonding conductor(s).

期待答案

可以。
虽然在60204中没有说明具体电阻数值是多少，可从其她标准中知道为0.5欧姆，美规为0.1欧姆。
如果你能过0.1欧姆比0.5欧姆的接地效果更好！

请问您所说的其他标准是和60204有些相似的标准么？还是什么标准？

弄明白了，产品接地线径是6mm2,按EN60204-1,表10是0.4欧，查询很简便！

不错的，
