(Specification)Standard Specification for ASTM Thermohydrometers with Integral Low-Hazard Thermometers
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.2.1.1 Discussion—
Originally, ledger paper was used especially for pen and ink records. Most ledger papers are surface sized, frequently subjected
to appreciable wear, and must have a high degree of permanence and durability.
