GB/T 22052-2008 in English

《GB/T 22052-2008用液体蒸气压力计测定液体的蒸气压力 温度关系和初始分解温度的方法》由TC251（全国危险化学品管理标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准为首次发布。本标准包括了纯液体蒸气压力、混合物的蒸气压力（在一封闭管中，填充量为40%±5%时）及纯液体和混合液体的初始热分解温度的测定。本标准适用于测试温度下，在硼硅酸盐瓶中其蒸气压在133Pa～101.3 kPa 间的液体蒸气压的测定。本测试方法温度适用范围为环境温度至748 K。如提供合适的恒温浴时，温度范围也可低于环境温度。

Scope

This standard includes the determination of the vapor pressure of pure liquid, the vapor pressure of mixture (in a closed tube, when the filling capacity is 40%±5%) and the initial thermal decomposition temperature of pure liquid and mixed liquid. This standard applies to the determination of the vapor pressure of liquids whose vapor pressure is between 133Pa and 101.3kPa in borosilicate bottles at the test temperature. The applicable temperature range of this test method is from ambient temperature to 748K. The temperature range may also be below ambient if a suitable constant temperature bath is provided. This standard has nothing to do with security, but is limited to use relevance. It is the responsibility of the user to establish appropriate safety and health practices before adopting this standard.
