有可能是合定版的
合定版的60950和60065已经实施了?
求高手啊:) 40A是加拿大标准提到的:该章测试需要参考另外一个标准CSA C22.2 No 0.4. losiondy 发表于 2014-4-3 17:53 static/image/common/back.gif

标准CSA C22.2 No 0.4中,
4.1.2 Procedure
4.1.2.1
The impedance test shall be conducted by passing a 60 Hz current from a part to be bonded to the
bonding terminal means and measuring the potential drop between them at the end of the period. The
current shall be as specified in Clause 4.1.2.2 and of the applicable duration specified in Table 4.
Table 4
Duration of impedance test current
(See Clause 4.1.2.1.)
Fusing of branch circuit required for equipment, A Time, min
0-30 2
31-60 4
61-100 6
101-200 8
201 and over 10
这里所提到的阻抗是指接地电阻么? 求高手!:(
