Bien que le but premier vis par cette norme soit nonc sous so rebrique Domaine dapplication, il est important de retenir quil incombe a /utilisateur de juger si/a norme convient a ses besoins particuliers. The Canadian Standards Association (CSA), under whose auspices this National Standard has
33、been pro- duced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1 973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in stand- ards development and certification activities. CSA standards reflect a national
34、 consensus of produc- ers 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 mu- nicipal, provincial, and federal governments in their regulations, part
35、icularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Can- ada indicate their support for CSAs standards develop- ment by volunteering their time and skills to CSA Committee work and supporting the Associations ob- j
36、ectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustain- ing memberships together form CSA s total membership from which its Directors are chosen. Sustaining mem- berships represent a major source of income for CSAs standards development activities. The A
37、ssociation 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 con- tinually audits and inspects products that bear the CSA Mark. In addition to its he
38、ad office and laboratory complex in Rexdale (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 cor- porate mission: CSA is an independent servi
39、ce organi- zation 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.

40、an Standards Association 178 Rexdale Boulevard Rexdale (Toronto), Ontario, Canada M9W 1R3 The Standards Council of Canada is the coordinat- ing body of the National Standards system, a federation of independent, autonomous organizations working to- wards the further development and improvement of vo
41、luntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of ad- vancing the national economy, benefiting the health, safety, and welfare of the public, assisting and pro tect- ing the consumer, facilitating
42、domestic and interna- tional trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individu
43、als whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, 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 contri
44、bution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the cri- teria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing r
45、esponsibility of the accredited standards- writing organization. Those who have a need to apply standards are encour- aged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the or
46、ganization preparing the standard. The responsibility for approving National Standards of Canada rests with the Standards Council of Canada 45 OConnor Street Suite 1200 Ottawa, Ontario K1P 6N7 0 Les normes nationales du Canada sont pub/lees en versions fran aise et anglaise. A/though the in tended p
47、rimary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the user to judge its suitability for their particular purpose.
