24、oordinating a 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 standardi
25、zation 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 furthenng international cooperation in the field of standards. c A National Standard of Canada is a
26、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 greatest practicable extent, a balance of representation of producers, users, consumers and
27、others with relevant interests, as may be appropnate to the subject in hand. It normally is a standard that is capable of making a significant and timely contnbution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria a
28、nd 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-writing organization. Those who have a need to apply standards are encouraged to use National Standar
29、ds of Canada whenever practicable. These standards are subject to penodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard.
