ASTM E1782 Thermocouple EMF-Temperature Table Verification Testing
ASTM E1782-14 is standard test method for determining the vapour pressure by thermal analysis. Vapor pressure is a fundamental thermophysical property of a liquid. Vapor pressure data are useful in process design and control, environmental regulations, estimation of volatile organic content (VOC), and in deriving hazard assessments. Vapor pressure and boiling temperature data are required for Material Safety Data Sheets (MSDS).
