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:
30.1 Pressure test at high temperature
The specimens are tested by means of the apparatus shown in figure 41. This apparatus has
a rectangular blade (see figure 41a) with an edge 0,7 mm wide, to be used in the case of
round pins, or a blade having a round shape (see figure 41b), with a diameter of 6 mm and an
edge of 0,7 mm, in other cases.
The specimens are placed in position as shown in figure 41.
The force applied through the blade is 2,5 N.
The apparatus, with the specimen in position, is maintained for 2 h in a heating cabinet at a
temperature of (200 ± 5) °C.
The specimen is then removed from the apparatus and, within 10 s, cooled by immersion in
cold water.
The thickness of the insulation remaining at the point of impression is measured and shall not
have been reduced by more than 50 % of its original value measured at the start of the test.
NOTE The values 2,5 N and (200 ± 5) °C are provisional.
当时我们采用PC6485的材料做, 结果是胶都融化了.
请各位帮忙是否做过类似测试?请帮忙提供可以通过此测试的塑胶材料.
谢谢各位了. |
