Acronyms & Abbreviations from the NIST Website

Here is a convenient reproduction of the list of acronyms and abbreviations from the NIST website. It contains a lot of terms that are specific to the work they do along with commonly used terms. With the well-known propensity the government has for generating creative acronyms, this will help to decipher their clever schemes.

 

This list is provided as a reference for the NIST Physics Laboratory's Technical Activities publication. It is not intended as a comprehensive list in the area of physics.
