问：是否只要套管的耐热温度高于电线实测温度20 °C，就不需要做电气强度测试。还是任何套管都要经过相应的电气强度测试，以满足Insulated linings, sleeves and similar parts shall have adequate mechanical, electrical，and thermal strength.

感谢楼上的回复，我想问的是，如果套管的耐热温度高于电线实测温度20 °C，是否需要根据第十章做电气强度测试（绝缘电阻和高压测试）。按字面意思说下面 a) b) c)所列的测试都是针对Thermal Strength 所需要做的，并未提及针对Electrical Strength的测试。

套管的耐热温度高于电线实测温度20 °C，前面还有一个前提条件的

问：EN60598-1:2004 条款4.14.1中Test A,Test B,TestC具体是指那种类型的灯具，请指点！
