    1. Rationale

    Technical Contact John T. Baron (Phone: 412 826 3980; e-mail: Rationale for Ballot The ASTM Mercury Removal Initiative is administered by ASTM Committee E20 on Temperature Measurement. One of its goal is to phase out the use of mercury thermometers. ASTM D4746-98(2008) in Section 6.1.1 requires the use of ASTM Thermometer 69C, a mercury thermometer. By revising this standard allowing the use of non-mercury alternative thermometers, users would have the option to procure and to test alternative thermometers thus promoting the phase out of mercury thermometers.
