Through the collaborative efforts ofCanadian standardization network

30、members, standardization ishelping to advance the social and economic well-being of Canadaand to safeguard the health and safety of Canadians. The networksefforts are overseen by SCC.The principal objectives of SCC are to foster and promote voluntarystandardization as a means of advancing the nation

32、adian standards development systemis the use of the following principles: consensus; equal access andeffective participation by concerned interests; respect for diverseinterests and identification of those who should be afforded accessto provide the needed balance of interests; mechanism for dispute

33、resolution; openness and transparency; open access by interestedparties to the procedures guiding the standards developmentprocess; clarity with respect to the processes; and Canadian interestconsideration as the initial basis for the development of standards.A National Standard of Canada (NSC) is a

34、 standard prepared orreviewed by an SCC-accredited SDO and approved by the SCCaccording to NSC approval requirements. Approval does not refer tothe technical content of the standard, as this remains theresponsibility of the SDO. An NSC reflects a consensus of a numberof capable individuals whose col

35、lective interests provide, to thegreatest practicable extent, a balance of representation of generalinterests, producers, regulators, users (including consumers) andothers with relevant interests, as may be appropriate to the subjectat hand. NSCs are intended to make a significant and timelycontribu

36、tion to the Canadian interest.Those 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 thatpublishes the standard.The responsibility for approving standards as NSCs rests w
