《GB/T 4207-2012固体绝缘材料耐电痕化指数和相比电痕化指数的测定方法》由TC301（全国电气绝缘材料与绝缘系统评定标准化技术委员会）归口，主管部门为中国电器工业协会。
Scope
This standard specifies the measurement methods for tracking resistance and relative tracking index of solid insulating materials, and is applicable to the occasions where alternating voltage is used for equipment components and disc materials. This standard specifies the measurement and test of corrosion damage as required The results cannot be directly used to estimate the safe creepage distance,
