首先,如果是二类器具,那么可接触外壳需符合双重绝缘或加强绝缘(绝缘漆恐怕厚度不够),绝缘厚度要求如下:+ u" [. S' M, U# N
29.3.1 The thickness of the insulation shall be at least# g9 P% I) g7 o! ^
– 1 mm for supplementary insulation;/ v: b3 N+ f' j* r, |: O7 r
– 2 mm for reinforced insulation.4 [+ L4 t Z+ p0 u d: p0 g3 a3 V- B7 M
/ d( Q0 I& V1 A7 b7 ^, {. ^4 f另外如果可接触绝缘外壳附加绝缘满足1mm或者加强绝缘满足2mm则不用做刮擦测试,见标准如下:* G6 B: ^ p: T! _, {$ l; d
21.2 Accessible parts of solid insulation shall have sufficient strength to prevent' t( l# {# \7 Z5 J
penetration by sharp implements.0 ?! A, [/ K/ i, d
Compliance is checked by subjecting the insulation to the following test, unless the thickness

如果确实厚度满足要求(这种情况很少见),则按二类器具打高压和测漏电流 |
