This method is for the determination of the vapor pressure of a pure liquid, the vapor pressure exerted by mixtures in a closed vessel at 40.5% ullage, and the initial thermal decomposition temperature of pure and mixed liquids. The method is applicable to liquids that are compatible with borosilicate glass and that have a vapor pressure between 133 Pa (1.0 torr) and 101.3 kPa (760 torr) at the selected test temperatures which range from ambient to 748K.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
