3、and Services. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users,
4、retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consen
5、sus process. CGSB has been accredited by the Standards Council of Canada as a national standards-writing organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In
6、addition to standards it pubiishes as national standards, CGSB produces standards to meet particular needs, in response to requests from a variety o sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the poli
7、cies described in the Policy Manual for the Development and Maintenance of Standards by CGSB. CGSB standards are subject to review and revision at any time, so as to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brough
8、t to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, will be found in the CGSB
9、 Catalogue, which is published annually and is available without charge upon request. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particul
10、ar purpose. Many tests required by CGSB standards are inherently hazardous. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. CGSB takes no position respecting the validity of any patent rights asserted w
11、ith any item connected with this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights are entirely their own responsibility.

12、s Services Canadian General Standards Board Ottawa, Canada K1A 1G6 The STANDARDS COUNCIL OF CANADA is the Co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in
13、 the national interest. The principal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national assisting and protecting the consumer, facilitating domestic and international trade, and furthering international co-operation in the field of sta
14、ndards. 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 greatest practicable extent, a balance of represe
15、ntation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard that is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicat
16、es 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-writing organization. Those who have a need to apply sta
17、ndards 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.
