GB/T 31229-2014 in English

《GB/T 31229-2014热重法测定挥发速率的试验方法》由TC279（全国纳米技术标准化技术委员会）归口，主管部门为中国科学院。
本标准规定了热重法测定样品挥发速率的方法。
本标准适用于使用热重分析仪测试25 ℃~500 ℃温度区间,单一挥发组分的挥发速率。本标准适用于测试挥发速率大于5μg/min的样品。本标准的使用者有责任确定是否需重复测试以及重复测试的次数,从而达到使用要求。
本标准不包括与其使用相关的所有安全问题。在使用本标准方法之前,使用者有责任建立适当的安全与健康规范,并确认规范的适用性。

Scope

This standard specifies the method for determining the volatilization rate of samples by thermogravimetric method. This standard applies to the use of a thermogravimetric analyzer to test the volatilization rate of a single volatile component in the temperature range of 25 °C to 500 °C. This standard is suitable for testing samples whose volatilization rate is greater than 5 μg/min. It is the responsibility of the user of this standard to determine whether and how often to repeat the test to meet the requirements for use. This standard does not cover all safety issues related to its use. Before using this standard method, it is the user's responsibility to establish appropriate safety and health practices and confirm the applicability of the specifications.
