GB/T 2522-2007 stipulates the test method for the surface insulation resistance and coating adhesion of electrical steel sheets (strips). The standard specifies the test principle, equipment requirements, sample preparation and test process, and specifies the insulation resistance measurement conditions and coating adhesion determination methods. It provides a unified technical standard for scientifically evaluating the surface insulation performance and coating mass of electrical steel sheets (strips), which helps to control the mass of products and meet the production and application needs of electrical fields.
