最近在一家实验室做带转换插头(VDE/BS/AU/CHN/US)电源的CB测试, 实验室要求对转换插头做EN50075和IEC60884-1的测试. 其中有一项测试为:
8 @$ ]$ @0 \! U7 R+ y7 t30.1 Pressure test at high temperature
. u- M) G O6 M* Y, ^1 F3 _The specimens are tested by means of the apparatus shown in figure 41. This apparatus has
- V4 S4 v0 S7 a) Ma rectangular blade (see figure 41a) with an edge 0,7 mm wide, to be used in the case of
