GB/T 36800.2-2018 Plastics—Thermomechanical analysis(TMA)—Part 2: Determination of coefficient of linear thermal expansion and glass transition temperature (English Version)
This part of GB/T 36800 specifies the method for determining the coefficient of linear thermal expansion of plastics in a solid state by using the principle of thermal expansion and using thermomechanical analysis (TMA). A method for determining the glass transition temperature by thermomechanical analysis is also specified. Note: Various types of thermal expansion instruments can be used to measure the coefficient of linear thermal expansion. This section only involves TMA instruments.
