BSI现在有新要求PVC要测球压吗

各位有谁了解BSI认证测试时会对PVC做70度一个小时的球压测试吗？我查1995标准只是一个耐热测试后对9.2.1及15.1.3进行检验通过就可以啊？还是有新的标准出来，请各位指点!

没有的，不管什么标准都不会对PVC的材料提出球压要求

对内芯支架要做70度球压试验，国内也要做，英国、欧盟都要做。

各位但现在我司送英国机构测试，实验室的工程师对BSEN60320-2001标准中24.1中章节中24.1.2 Parts of insulating material, of appliance inlets not integrated in or incorporated in anappliance or equipment and of connectors, shall be subjected to a ball-pressure test by meansof the apparatus shown in figure 23.Parts of the cord anchorage and the cord guard, parts not immediately surrounding the socketcontacts of connectors moulded together with the cord, and parts of ceramic are not subjectedto this test.Before the test is started, the ball and the support on which the specimen shall be placed, arebrought to the temperature specified. The part under test shall be placed on a 3 mm thick steelplate in direct contact with it, so as to be supported to withstand the test force. When it is notpossible to carry out the test on the specimen, the test shall be carried out on a specimen ofthe same material at least 2 mm thick.The surface of the part to be tested is placed in the horizontal position and a steel ball of 5 mmdiameter is pressed against the surface with a force of 20 N.The test is made in a heating cabinet maintained at a temperature of–155 °C ± 2 °C in the case of accessories for very hot conditions;–125 °C ± 2 °C in the case of accessories for hot conditions;–125 °C ± 2 °C for those parts of accessories for cold conditions which retain current-carrying parts and parts of the earthing circuit in position;–75 °C ± 2 °C for other parts of accessories for cold conditions and all parts of 0,2 Aappliance couplers.After 1 h, the ball is removed from the specimen which is then cooled down, within 10 s, toapproximately room temperature by immersion in cold water.说就是要对PVC球压，我们应如何应对呢？请何京老板提提你的看法？
