8、Canada (SCC) is the coordinating body of theCanadian standardization network, which is composed of people andorganizations involved in the development, promotion and implementationof standards. Through the collaborative efforts of Canadianstandardization network members, standardization is helping t
9、o advancethe social and economic well-being of Canada and to safeguard thehealth and safety of Canadians. The networks efforts are overseen bySCC.The principal objectives of SCC are to foster and promote voluntarystandardization as a means of advancing the national economy,supporting sustainable dev
10、elopment, benefiting the health, safety andwelfare of workers and the public, assisting and protecting the consumer,facilitating domestic and international trade, and furthering internationalcooperation in relation to standardization.An important facet of the Canadian standards development system is
11、 theuse of the following principles: consensus; equal access and effectiveparticipation by concerned interests; respect for diverse interests andidentification of those who should be afforded access to provide theneeded balance of interests; mechanism for dispute resolution; opennessand transparency
12、; open access by interested parties to the proceduresguiding the standards development process; clarity with respect to theprocesses; and Canadian interest consideration as the initial basis for thedevelopment of standards.A National Standard of Canada (NSC) is a standard prepared orreviewed by an S
13、CC-accredited SDO and approved by the SCCaccording to NSC approval requirements. Approval does not refer to thetechnical content of the standard, as this remains the responsibility of theSDO. An NSC reflects a consensus of a number of capable individualswhose collective interests provide, to the gre
14、atest practicable extent, abalance of representation of general interests, producers, regulators,users (including consumers) and others with relevant interests, as maybe appropriate to the subject at hand. NSCs are intended to make asignificant and timely contribution to the Canadian interest.Those
15、who have a need to apply standards are encouraged to useNSCs. These standards are subject to periodic review. Users of NSCsare cautioned to obtain the latest edition from the SDO that publishes thestandard.The responsibility for approving standards as NSCs rests with:Standards Council of Canada270 A
