PML Working for You

The work we do at NIST’s Physical Measurement Laboratory (PML) affects many aspects of your everyday activities and quality of life. But often our contributions — though very important — are not readily apparent. To help you understand how PML works for you, we’re producing a series of short, easily readable, reports and posting them here.

You can use the links in the blue column on the left or the back and forward links at the bottom of the page.

If you have questions, or comments, about the articles, please pml-webmaster [at] nist.gov (subject: PML%20Working%20for%20You) (contact us)!

We hope you'll learn more about us and how we are striving to meet the ever-changing demands of industry and science.
