37、es 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-profit, nonstatutory, voluntary membership association engaged in standards development and certification activities. CSA sta
38、ndards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in th
39、eir regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work and supporting the A
40、ssociations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standards development activit
41、ies. 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 certification process, the Association regularly and continually audits and inspects products that bear the CSA Mark. In addition t
42、o 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 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an independent service o
43、rganization 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 and related services to meet national and international needs.For further information on CSA services, write toCanadian Stand

45、dization in the national interest.The principal objects of the SCC are to fosterand promote voluntary standardization as a meansof advancing the national economy, benefiting thehealth, safety, and welfare of the public, assistingand protecting the consumer, facilitating domesticand international tra
46、de, and furthering internationalcooperation in the field of standards.A National Standard of Canada (NSC) is a standardprepared or reviewed by an accredited Standards Development Organization (SDO) and approved by the SCC according to the requirements of CAN-P-2. Approval does not refer to the techn
47、ical content of the standard; this remains the continuing responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (
48、including consumers), and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest.Those who have a need to apply standards areencouraged to use NSCs. These standa
49、rds are subjectto periodic review. Users of NSCs are cautionedto obtain the latest edition from the SDO which publishes the standard.The responsibility for approving standards as National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaCette Norme nationale du Canada est offerte en anglais et en franais.Although the intended primary application of this Standard is stated in its Scope, it is importantto note that it remains the responsibility of the users to judge its suitability for their particul
