3、th SCCs:Requirements and Guidance-Accreditation for Standards Development Organizations, and Requirements and Guidance-Approval of National Standards of Canada Designation. More information on National Standard requirements can be found at www.scc.ca. An SCC-approved standard reects the consensus of
4、 a number of experts whose collective interests provide, to the greatest practicable extent, a balance of representation of affected stakeholders. National Standards of Canada are intended to make a signicant and timely contribution to the Canadian interest. SCC is a Crown corporation within the por
5、tfolio of Industry Canada. With the goal of enhancing Canadas economic competitiveness and social well-being, SCC leads and facilitates the development and use of national and international standards. SCC also coordinates Canadian participation in standards development, and identies strategies to ad
6、vance Canadian standardization efforts. Accreditation services are provided by SCC to various customers, including product certiers, testing laboratories, and standards development organizations. A list of SCC programs and accredited bodies is publicly available at www.scc.ca. Users should always ob
