Class: Pubid::Csa::Identifiers::Cec

Inherits:
SingleIdentifier show all
Defined in:
lib/pubid/csa/identifiers/cec.rb

Overview

Canadian Electrical Code (CEC) identifier Pattern: CSA C22.2,3,4,6 NO. number:year Examples: CSA C22.2 NO. 286:23, CSA C22.3 NO. 7:20

The “NO.” indicates a numbered standard within the C22.x series and must be preserved (not normalized) as a semantic component.
