IEC 60851-5:20 08规定了以下试验: -测试5:电阻； -测试13:击穿电压； -测试14:绝缘的连续性； -测试19:介电耗散因子。 对上一版的重大修订包括以下几点: -在子条款5.3中，增加使用碳刷电极用于在高压连续性测试期间计数不连续性，作为V形槽滑轮电极的替代；和 -关于大于2,500 mm的圆形导线和纤维包覆导线的击穿电压试验的说明。

IEC 60851-5:2008 specifies the following tests:
- Test 5: Electrical resistance;
- Test 13: Breakdown voltage;
- Test 14: Continuity of insulation;
- Test 19: Dielectric dissipation factor.
Significant revisions to the previous edition include the following points:
- In Subclause 5.3, the addition of the use of carbon brush electrodes for the counting discontinuities during the high voltage continuity test, as an alternative to the V-groove pulley electrode; and
- Clarifications in the breakdown voltage test for round wires larger than 2,500 mm and for fibrous covered wires.
