首先要弄清楚一点:

9.2 Insulation resistance at high temperature: Sample a suitable length of a core specimen from the product, immerse it in water at a spesified temperature +-1 C, until the temperature of the insulation is stabilized, and then measure the insulation resistance by the method of 9.1. Do not carry out temperature conversion. z! k- o! b+ S4 p
这段话中,抽取的是CORE SPECIMEN,参考国标70C绝缘电阻测试方法,这指的应该是芯线。
