GB/T 4 2919.4 - 2023 stipulates that the laser flashing method is used to determine the thermal conductivity and thermal diffusion coefficient of plastics. It is clearly applicable to a variety of plastics, describes the principle of laser flashing method, and strictly regulates the equipment, sample preparation, test steps, data processing, etc. According to this standard, it can accurately measure the thermal performance parameters of plastics, provide material selection basis for plastics in industries with high thermal management requirements such as electronics, construction, and automobiles, and help optimize product thermal design and improve product performance and mass.
