ActivePlastics—Determination of temperature of deflection under load一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 under a specified bending load. It is applied in material quality control and product development for the plastics industry, particularly for evaluating the heat resistance of thermoplastics and thermosetting materials used in automotive, electronic, and consumer goods components. The test is conducted under controlled laboratory conditions to compare thermal performance across different plastic formulations or production batches.
