AbolishedPlastics--Determination of temperature of deflection under load--Part 1:General test method
塑料 负荷变形温度的测定 第1部分:通用试验方法
Application Summary AI generated
This standard specifies the general test method for determining the temperature at which a plastic specimen deflects a specified amount under a constant bending load. It is applied in the plastics manufacturing and quality control industries to assess the heat resistance of rigid plastics and molding materials under load. The method is used for material comparison, quality assurance, and design data generation, particularly for products exposed to elevated temperatures in service.
