GB/T 42426-2023 Chemicals—Vapor pressure test
Abstract
This document describes the measurement methods for chemical vapor pressure tests using dynamic methods, static methods, liquid vapor pressure gauge methods, exudation methods - vapor pressure equilibrium, exudation methods - Nozzle tank, exudation methods - isothermal thermal weight, gas saturation methods, and rotary methods. This document is suitable for measuring the vapor pressure of solids and liquids in the range of 10-10 Pa to 105 Pa, and is used for samples that do not decompose under the specified measurement conditions. When the above conditions are not applicable, the vapor pressure estimation methods in Appendix A can be referred to. A comparison of vapor pressure test methods is shown in Table 1.
