Abstract

NIST Handbook 44 was first published in 1949, having been preceded by similar handbooks of various designations and in several forms, beginning in 1918. NIST Handbook 44 is published in its entirety each year following the Annual Meeting of the National Conference on Weights and Measures (NCWM). As a result of circumstances surrounding the COVID-19 pandemic, a 2021 edition of NIST Handbook 44 was not published. The Committee on Specifications and Tolerances of the NCWM developed the 2022 edition with the assistance of the Office of Weights and Measures (OWM) of the National Institute of Standards and Technology (NIST). This handbook includes amendments endorsed by the 105th and 106th National Conference on Weights and Measures during its Annual Meetings in 2021.
