NIST Handbook 44 2013 Edition now available for Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices

NIST HDBK 44, “Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices,” has just be revised and the new 2013 edition is now available from Document Center Inc. in either paper or pdf format.  The handbook is published annually to support the mission of NIST’s  Office of Weights and Measures – to promote uniformity in U.S. weights and measures laws, regulations, and standards.

Handbook 44 has been around in various formats since 1918, but was first published with it’s current number and title in 1949.  It is actually written by the National Conference on Weights and Measures (NCWM), an association of State and local weights and measures officials and representatives of business, consumer groups, and Federal agencies.

Changes from the 2012 Edition of NIST Handbook 44 are included in a 2 page table found in the foreward.  You’ll see that modifications have been made to sections 2.20, 2.21, 3.30, 3.36, 5.58, 5.59, and Appendix D.  And there are other editorial changes as well (which do not affect the technical content of the handbook).  They are found in sections 1.10, 2.20, 2.21, 3.33 and 3.34.

NIST (the National Institute of Standards and Technology) has been providing the support for our national Metrology program since it’s inception as the National Bureau of Standards (NBS) back in March of 1901.  It not only provides calibration services, but also provides a leadership role for the Federal support and development of Standards and emerging technologies.  That’s why you’ll see NIST as the co-ordinator for the U.S. cybersecurity standards that we discussed in our blog last week…
