GB/T 4 2919.3 - 2023 focuses on the thermal conductivity detection of plastics, and uses temperature wave analysis to determine the thermal conductivity and thermal diffusion coefficient of plastics. The standard specifies the applicable plastic types, elaborates the principle of temperature wave analysis, and specifies the instrumentation, sample preparation, test operation process and data processing. According to this standard, the thermal performance parameters of plastics can be accurately determined, providing key material selection for plastics in many fields that require thermal performance, such as electronics, Encasement, etc., to help related industries improve the level of product thermal performance design.
