probel b?看下标准吧,可见灼热元件是probel 41 / V3 s+ \+ K1 H
没错,你看的应该是防触电里面的要求,确实是说不用probe B而是用Probe 41。但我的问题是爬电距离的问题。你可以看看标准定义:# Y6 ]8 C. N' L8 V2 U# B" ^# j
爬电距离:shortest distance along the surface of insulation between two conductive parts or between a, v& _4 X6 l8 |& Q4 ]* }/ d
conductive part and the accessible surface
Z4 D5 }% W8 E6 ~9 O5 p* |, i- e可接触表面:part or surface that can be touched by means of test probe B of IEC 61032, and if the part or! i% j N7 n+ s6 {7 G: |

单从定义来讲并未说是用probe 41来判定可接触表面的界定。 |
