This guide deals mainly with voluntary consensus standards [VCS] developed by national and international Science / Technology / Medical standards development organizations [SDOs]. 

“Voluntary consensus standards developed by industry in accordance with procedures for due process, openness and consensus are often subsequently adopted by the government as part of the regulatory framework.” VCSs are not laws, but some may be referenced or incorporated in regulations, e.g. Canadian electrical code.

Requests for proposals and contracts for services frequently cite standards which must be met. Engineering societies support members who develop products that meet their standards. In legal cases, this protection can be very important.
