My document for version 2.0 (NBSIR 82-2631) defines the acronym IGES as:
Initial Graphics Exchange Specification, and is prepared by the
National Bureau of Standards.

The address on the cover sheet is:

		U.S. DEPARTMENT OF COMMERCE
		National Bureau of Standards
		National Engineering Laboratory
		Center for Manufacturing Engineering
		Automated Production Technology Division
		Washington D.C. 20234

I beleive that IGES has matured to version 4, and will stay at that
version.  It is supposedly going to be replaced with a standard
called PDES, which I beleive is an acronym for:
Product Definition Exchange Specification.
