NIST Handbook 105-6 Specifications & Tolerances for Reference Standards & Field Standard Weights & Measurements - 6- Specifications & Tolerances for Thermometers. ; 5 U.S.C. Clinical Laboratory and Standards Institute (CLSI): NIST Temperature and Humidity Group staff have worked with CLSI staff to update standards calling for the use of mercury-in-glass SRM thermometers, enabling laboratories to use other thermometer types with NIST traceability. The thermometer measures changes in frequency, as measured by electronics, then maps those changes to a temperature. NIST is committed to the health and safety of our employees and the American public and is supporting social distancing efforts. ScienceDaily. 271 et seq.
