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.
