regional standard A Regional standard is one that applies across a multi-nation region. Most countries have their own national standards-making bodies, which in turn may also group together to make regional standards. For example, national standards bodies in Europe are also members of the European Committee for Standardization (CEN) as well as members of ISO. The use of such standards may be voluntary, or they may be referenced in regulation (therefore mandatory).
