各位但現在我司送英國機構測試，實驗室的工程師對BSEN60320-2001標準中24.1中章節中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.說就是要對PVC球壓，我們應如何應對呢？請何京老板提提你的看法？ |
