NIST Handbook 44 includes specifications, tolerances, and other technical requirements for weighing and measuring devices. These requirements are intended to encourage the design, installation, testing, and use of weighing and measuring devices that provide for accurate, repeatable measurements; facilitate clear and transparent transactions for buyer and seller; and do not facilitate fraud. Handbook 44 is adopted by many state, local, and some federal weights and measures authorities to apply to commercial weighing and measuring equipment and associated equipment and for use in applications for law enforcement and the collection of statistical information by government agencies. NIST has a statutory responsibility for cooperation with the states in securing uniformity of weights and measures laws and methods of inspection and publishes this and other NIST Handbooks in partial fulfillment of this responsibility. NIST Handbook 44 was first published in 1949, having been preceded by similar handbooks of various designations and in several forms, beginning in 1918; the handbook is now typically published on an annual basis. This 2023 edition includes amendments made through the Committee on Specifications and Tolerances of the National Conference on Weights and Measures (NCWM) with technical guidance from the Office of Weights and Measures (OWM) of the National Institute of Standards and Technology (NIST) and input from weights and measures officials and industry representatives. These amendments were adopted by the NCWM at its 107th Annual Meeting in July 2022.
The NIST Office of Weights and Measures (OWM) presents its first report 2022 NIST Annual Summary of U.S. Legal Metrology Activities report. This report includes a summary of changes made to NIST Handbook 44 (2021) Specifications, Tolerances and Other Technical requirements for Commercial Weighing and Measuring Devices, NIST Handbook 130 (2021), Uniform Laws and Regulations in the Areas of Legal Metrology an Engine Fuel Quality, and NIST Handbook 133 (2020), Checking the Net Contents of Packaged Goods. The summary will provide an archival record of proposals and associated actions with the goal of assisting the weights and measures community in consistently interpreting and implementing NIST Handbooks 44, 130, and133. Included within each item in this report is an NIST OWM technical analysis, background information, and a summary of any actions taken on proposed changes to these NIST Handbooks considered in 2022
