UpcomingPlastics—Differential scanning calorimetry(DSC) method—Part 2:Determination of glass transition temperature and step height
塑料 差示扫描量热（DSC）法 第2部分：玻璃化转变温度和台阶高度的测定
Application Summary AI generated
This standard specifies a differential scanning calorimetry (DSC) method for determining the glass transition temperature and step height of plastics. It is applied in quality control and material characterization within the rubber and plastics industry, particularly for assessing thermal properties of polymers during production, formulation development, or incoming material inspection. The method is used to evaluate amorphous or semi-crystalline materials, such as thermoplastics and elastomers, under controlled heating and cooling conditions.
