最近在看IEC 62133:2012 的标准经常遇到问题,如8.3.9条款中有一段话,不是很理解还请高手帮忙分析分析。
4 k ?7 m! I( [7 m6 iBottom surface of movingpart of the press equipment is made of Nitrile rubber or Acryl, which is put onthe 10 mm x 10 mm stainless steel shaft. The detail of pressing jigs shall beshown in Figure 2. Nitrile rubber bottom surface is for cylindrical cell test.For prismatic test 5 mm x 5 mm (2 mm thickness) Acryl is put on the Nitrilerubber. The fixture is moved down at the speed of 0,1 mm/s monitoring the cellvoltage. When voltage drop caused by the internal short circuit is detected,stop descent immediately and keep pressing jig in the position for 30 s andthen release the pressure. Voltage is monitored m-ore than 100 times per secondand if voltage is dropped more than 50 m V compare to the initial voltage, itis defined to internal short circuit has occurred. If the pressure reaches 800N for cylindrical cell and 400 N for prismatic cell, stop descent immediatelyand then keep in the position.8 O. \2 V& Y3 r# c* D) u/ m, ~, G
