Scope: This guiding technical document specifies the requirements, test methods, inspection rules, marking, packaging, transportation and storage of halogen-free flame-retardant high-strength glass cloth laminates. This guiding technical document is applicable to the non-alkali glass cloth treated with the coupling agent as a reinforcing material, impregnated with a halogen-free flame-retardant resin with a temperature index of 155, and hot-pressed to form a halogen-free flame-retardant high-strength glass cloth layer platen. Halogen-free flame-retardant high-strength glass cloth laminate has a high thermal mechanical strength retention rate, suitable for motors and electrical equipment with a temperature index of 155, used as insulating structural parts, and can be used in humid environments and transformer oil
