CSA standards reflect a national consensus of producers and users - including manufacturers, consumers, retailers, unions and professional

13、 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, parlicularly in the fields of health, safety, building and construction, and the environment. Individuals, compa

The more than 7000 committee volunteers and the 2000 sustaining membership

The Association offers certification and testing services in support of and as an extension to its standards development act

26、 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 oi the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthe

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 individuals whose collective interests provide to the

28、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

29、 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-develo
