IEC 60320标准理解
IEC 60320-1标准中,球压测试是这样描述的:Before the test is started, the ball and the support on which the specimen shall be placed, are brought to the temperature specified. The part under test shall be placed on a 3 mm thick steel plate in direct contact with it, so as to be supported to withstand the test force. When it is not possible to carry out the test on the specimen, the test shall be carried out on a specimen of the same material at least 2 mm thick.
最后一句"如果不可能在试样上进行试验时,应在至少2mm厚与试样相同的材料上进行试验", 那么如果我们的样品测试点的厚度没有达到2mm, 是不是达到了不可能在试样上进行试验的条件,而可以另取相同材料的2mm厚的塑料板来进行测试? 好象可以几片同等材质叠加的
