GB/T 4207-2012
AbolishedMethod for the determination of the proof and the comparative tracking indices of solid insulating materials
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
Application Summary AI generated
This standard specifies test methods for determining the comparative tracking index (CTI) and proof tracking index (PTI) of solid insulating materials under wet and contaminated conditions. It is applied in the electrical and electronics industries to evaluate the resistance of insulating materials to surface tracking caused by electrical stress and moisture, ensuring safety and reliability in products like connectors, switchgear, and printed circuit boards. The standard is used during material qualification, quality control, and design verification for components exposed to high-voltage environments.
