GB/T 2522-2007
AbolishedMethods of test for determination of surface insulation resistance and lamination factor of electric sheet and strip
电工钢片（带）表面绝缘电阻、涂层附着性测试方法
Application Summary AI generated
This standard specifies test methods for measuring the surface insulation resistance and coating adhesion of electrical steel sheets and strips. It is applied in the metallurgy and electrical manufacturing industries to evaluate the insulating properties of grain-oriented and non-oriented silicon steel used in transformers, motors, and generators. The testing ensures the material meets performance requirements for lamination efficiency and resistance to inter-laminar short circuits.
