ASTM E2995-14

Standard Specification for ASTM Thermohydrometers with Integral Low-Hazard Thermometers

SCOPE
1.1 This specification covers glass thermohydrometers of various scale graduation systems, intended for use in a variety of ASTM Test Methods.  
1.2 The thermohydrometers presented in this standard are not exact replacements for the thermohydrometers in Specification 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.
