    Revision of D1945 - 03(2010) Standard Test Method for Analysis of Natural Gas by Gas Chromatography

    (What is a Work Item?)

    Active Standard: D1945 - 03(2010)

    Developed by Subcommittee: D03.07 | Committee D03 | Contact Staff Manager


    1. Rationale

    ASTM Headquarters is mandating a review of standards that use mercury and determine if its use is still appropriate or if it should be removed, or replaced with a non-mercury alternative. D1945 includes a mercury manometer to monitor the pressure of the gas sample loop. Safer modern alternatives exist such as digital manometers and absolute pressure transducers. Section 5.11 has been rewritten to allow any type of vacuum gauge (including mercury manometers). Figure 1 has been replaced with a diagram containing a generic pressure indicator. References to pressure in mm Hg have been removed and replaced with the SI unit Pascal.
