Standards

NIST (US National Institute of Standards and Technology) was kind enough to post their "Guidelines for Evaluating and Expressing the Uncertainty of NIST Measurement Results" (NIST Technical Note 1297) at:
http://www.physics.nist.gov/Pubs/guidelines/contents.html

More information from NIST on the "Essentials of expressing measurement uncertainty" is available online at:
http://physics.nist.gov/cuu/Uncertainty/index.html

To order a copy of ANSI/NCSL Z540-2, "U.S. Guide to the Expression of Uncertainty in Measurement", go online to:
