1、Standards Canadian Association CAN3-CI 7-M84 Alternating-Current Electricity Metering Electric Power Systems and Equipment U-J A NationaI Standard of Canada The Canadian Standards Association (CSA), under whose auspices this National Standard has been pro- duced, was chartered in 1919 and accredited

2、 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 manufacturer

3、s, 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 const

4、ruction, 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 Associations objectives through sustaining memberships. The more than 6000 committ

5、ee volunteers and the 2200 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 activities. The Association offers certification and testing services in support of and

6、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 head office and laboratorycomplex in Rexdale (Toronto), CSA has regional

7、branch offices in major centres across Canada and inspection and testing agencies in eight countries. During 65 years of operation, the Association has developed the necessary expertise to meet its corporate mission: “to provide Canadian standards and related activities for the benefit of the Canadi

8、an public, government, and business“. For further information on CSA services, write to Canadian Standards Association 178 Rexdale Boulevard Rexdale (Toronto), Ontario, Canada M9W 1R3 The Standards Council of Canada is the coordinating body of the National Standards System, a federation of independe

9、nt, 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, sa

10、fety, and welfare of the public, assisting 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 wh

11、ich reflects a reasonable agreement among 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. I

12、t 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

13、not refer to the technical content of the standard; this remains the continuing responsiblity of the accredited standards-writing organization. Those who have a need to apply standards are encouraged to use National Standards of Canada when- ever practicable. These standards are subject to periodic

14、review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard.
