NIST OWM staff develop and publish technical articles on a variety of legal metrology topics to encourage and promote uniformity in weights and measures requirements and their implementation and methods of inspection.
To search the content of this page, use Ctrl-F via your keyboard. For example, articles related to "scales" or "electric vehicles" may be located by words in the Title or Keywords.
An Excel version of the table is here, allowing the information to be sorted by Topic Area or Keywords.
The following table provides a selection of technical articles published in past OWM newsletters. Recent articles (April 2022 to present) are maintained as individual webpages as listed on the OWM landing page and are hyperlinked through the article title. This content may be updated and noted by an 'Updated' date on the individual page. Past articles (before April 2022) are provided as PDF or Word documents. These are not updated and thus contain information that is only current as of the publication date.
