    17、 open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by

Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to

NSCs are intended to make a significant and timely contribution to the Canadian int

Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard. The responsibility for approving standards as NSCs rests withStandards Counci
