Through the collaborative efforts ofCanadian standardizatio

29、n network 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
