In the free, downloadable paper described in an earlier news article, The Role of Standards & Calibration in IR Thermography there is a long list of possible sources of other standards either now and, more likely, in the not too distant future.
The list was culled from various sources on the Web and is listed below with live links to each of the organizations.
Since I researched for the article some newer standards resources have been found. Perhaps the most useful are the new pages on the NIST website, specifically: NIST Global Standards Information.
The latter page may change over time, but another resource described in my paper that has a useful list of standards sources is the “Internet Resources for Standards Developing Organizations” on the American National Standards Institute webpage: www.ansi.org/internet_resources/standards_devel_organizations/resources.aspx?menuid=12
