This NIST Handbook 44 course covers the history, organization, and intended use of NIST Handbook 44 (based on the 2009 edition). It also provides instruction on NIST Handbook 44 terminology, how to locate specific paragraphs, use of the NCWM final reports to understand the application of specific sections, and use of requirements in conjunction with the NIST Examination Procedure Outlines.
This course is designed for use as a self-study activity to work on your own and without an instructor. However, the course can also be used for group activities and discussion. While this course is particularly relevant for newer inspectors, it is also valuable for more experienced inspectors to enhance their understanding and use of the NIST Handbook 44.
OWM “Study Guides” are designed for use by weights and measures officials and service personnel to enhance and strengthen their knowledge of specific areas of legal metrology inspection and testing and to assist individuals in their professional development. They are also intended for use with NIST Handbooks 44, 130, and 133 and to supplement more comprehensive training and development opportunities.
Below are links to study guides for several field inspection areas:
Included in each study guide are the following:
OWM Examination Procedure Outlines (EPOs) are designed to serve as a guide for the field examination of commercial weight and measuring devices. They include inspection and test procedures, with code references to NIST Handbook 44, “Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices.”
The available EPOs are posted here. Most are based on the 2015 edition of NIST Handbook 44, with the exception of the recently published EPO 29 - Hydrogen Gas Retail Vehicle Fuel Dispensers and EPO 30 - Electric Vehicle Fueling Systems which are based on the 2025 edition.
Older EPO versions based on the 2002 edition of NIST Handbook 44 were also published in NIST Handbook 112, "Examination Procedure Outlines (EPOs) for Commercial Weighing and Measuring Devices". If you employ any of these EPOs as a guide for field examinations, please conduct a cross-check to the current version of NIST Handbook 44 for your intended use and application.
Many of the EPOs are being updated to align with the 2025 version of NIST Handbook 44, which will include a revision of the NIST Handbook 112 to reflect these updates (anticipated in early 2025). OWM is also working on new EPOs to include:
