Slide 3 of ANSI’s “Standards and Conformity Assessment Bodies of the United States” (PPT, version 2006-07-21):
Explanation:
The primary purpose of the chart is to attempt to portray, in high-level, block diagram form, the entities of the standards and conformity assessment systems of the United States, their and primary inter-relationships and relationships to international and regional organizations—on one slide. The U.S. systems are complex, and so subsequently is the chart. [...] The chart is one perspective of the systems, with emphasis on identification and representation of the various entities. The chart would look different if the entities were drawn proportional to their relative work volumes in the systems, or if they were drawn proportional to their respective standards and conformity assessment revenues or budgets. [slide 2]
ANSI:
Standards Activities/Country Charts - Standards and Conformity Assessment Systems (for Brazil, Canada, China, EU, India, Japan, Korea, Mexico, Russia, the US, and Thailand—what do they have in common?)
The ANSI-administered NSSN (“A National Resource for Global Standards”)—note the search engine—doesn’t seem to think that an expansion of its own acronym would be of interest to anyone. (One possibility: National Standards Systems Network?)
