该测试方法包括通过差示热分析或差示扫描量热法测定聚合物的玻璃化转变温度。该测试方法适用于颗粒状聚合物（低于60目，如有可能避免研磨）或可切割适当样品的任何制造形状。该测试方法对于规范验收是有用的。该测试方法根据温度变化确定聚合物的行为

This test method covers determination of glass transition temperature of polymers by differential thermal analysis or differantial scanning calorimetry. This test method is applicable to polymers in granular form (below 60 mesh, avoiding grinding if possible) or to any fabricated shape from which appropriatesamples can be cut. This test method is useful for specification acceptance. This test method determines the behaviour of a polymer according to the variations of temperatures.
