scope:

This test method covers visual and dimensional inspection and test for scale accuracy to be used in the verification of liquid-in-glass thermometers as specified in Specifications E1 and E2251. However, these procedures may be applied to other liquid-in-glass thermometers.²

NOTE 1-The use of NIST SP250-23² is recommended.

Warning-Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney and liver damage.
