GB/T 1303.2-2009 is the second part of the standard for thermosetting Resin industrial hard laminates for electrical use, focusing test methods. The standard system specifies the Measuring method for the appearance and size of the laminate, specifies the electrical performance (such as dielectric strength), Mechanical Property (such as flexural strength), physical and chemical performance (such as water-absorption) and other key indicators of the test process, standardizes the test environment, equipment use and data processing requirements, and provides a unified technical specification for the accurate detection of the mass of this type of laminate.
