Les normes CSA reflbtent le consensus de producteurs et d’usagets de partout au pays, au nombre desquels se trouvent des fabricants, des consommateurs, des dbtaillants et des representants de syndicats, de corps professionnels et d’agences gouvernementales. L’utilisation des normes CSA est trhs repandue dans I’industrie et le commerce, et leur adoption A divers ordres de 16gislation, tan! municipal et provincial que fddbral, est chose courante, particulihment dans les domaines de la santd, de la s6curit6, du bdtiment, de la construction el de t’environnement. Les Canadiens d’un bout B I’autre du pays tdmoignent de leur appui au travail de normalisation men6 par la CSA en participant bbndvolement aux travaux des comites de la CSA et en appuyant ses objectifs par leurs cotisations de membres de soutien. Les quelque 7000 volontaires faisant partie des comitds et 18s 2000 membres de soutien constituent I’ensemble des membres de la CSA parmi lesquels ses administrateurs sont choisis. Les cotisations des membres de soutien representent une source importante de revenu pour les services de soutien B la normalisation volontaire.

The Canadlan Standards Assaclation (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-profit, 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 standards 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 their support for CSA’s standards development by volunteering their time and skills to CSA Committee work and supporting the Association’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA’s total membership from which its Directors are chosen, Sustaining memberships represent a major source of income for CSA’s 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 certification 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 Etobicoke, 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 organization whose mission is to provide an open and effective forum for activities lacilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

The Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field 01 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 af capable individuals 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 contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-development organization. Those who Rave a need to apply standards are encouraged 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 organization preparing the standard.
