20、org/legal to find out how we protect your personal information.The Canadian Standards Association (CSA), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-pr
21、ofit, nonstatutory, voluntary membership association engaged in standards development and certification activities. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The s
22、tandards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate th
23、eir support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which
24、 its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certific
25、ation process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since
26、 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification an

29、health, safety, and welfare of the public, assistingand protecting the consumer, facilitating domesticand international trade, and furthering internationalcooperation in the field of standards.A National Standard of Canada (NSC) is a standardprepared or reviewed by an accredited Standards Developmen

Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the SDO.
