3、2:04(ISO/IEC 15992:2003)International Standard ISO/IEC 15992:2003 (second edition, 2003-04-01) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 15992:04, which has been approved as a NationalStandard of Canada by the Standards Council of Canada.ISBN 1-55397-704-1 December 2

4、004The 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-profit, nonstatutory, voluntary membership association engaged

5、 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

6、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 CSAs standards development by volunteering t

7、heir 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 its Directors are chosen. Sustaining memberships represent

8、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 certification process, the Association regularly and continually aud

9、its 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 1919, the Association has developed the necessary expertise

10、 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 and related services to meet national and international needs.

12、ds 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

13、 and protecting the consumer, facilitating domestic and international 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

14、the views of a number of 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

15、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

16、standard; this remains the continuing responsibility of the accredited standards development organization. Those who have 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

17、to obtain the latest edition from the organization preparing the standard.The responsibility for approving National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaAlthough the intended primary application of this Standard is sta
