ASTM WK27505

    New Specification for ASTM Thermohydrometers with Integral Low-Hazard Thermometers

    (What is a Work Item?)

    Developed by Subcommittee: E20.05 | Committee E20 | Contact Staff Manager


    1. Scope

    1.1 This specification covers glass thermohydrometers of various scale graduation systems intended for use in a variety of ASTM International test methods. 1.2 The thermohydrometers presented in this specification are not exact replacements for the thermohydrometers in ASTM E100; the thermometers have larger maximum permissible scale errors than do their Hg-filled counterparts. The user should decide if these thermohydrometers are appropriate for use in his or her application. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This specification is being written to provide non-mercury thermohydrometers for use in ASTM test methods. By creating a standard, the technical committees will have the opportunity to choose instruments appropriate for their test methods.
