Directory of Accredited Laboratories


This directory was last updated on November 28, 2008. New and updated scopes of accreditation are posted monthly. Users of this directory who are considering selection of an accredited laboratory should be aware of the effective dates of the accreditation and verify that the laboratory has retained its accreditation at the time its services are to be provided.


Search On-Line Directory

The NVLAP Directory of Accredited Laboratories is fully searchable, using Google Search. You may search both testing and calibration scopes of accreditation by typing one or more search terms into the search box below and pressing the 'Enter' key or clicking on the Google Search button.

Google searches are NOT case sensitive. All letters, regardless of how you type them, will be understood as lower case. By default, Google only returns pages that include all of your search terms. There is no need to include "and" between terms. Google ignores common words and characters such as "where" and "how," as well as certain single digits and single letters, because they tend to slow down your search without improving the results. Google will indicate if a common word has been excluded by displaying details on the results page below the search box.
