The CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards c

7、ommittees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professionai and trade societies, and research and testing organizations. A

8、ny given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. The CGSB has been accredited by the Standards Council of Canada as a national standards-writing organization. The standards

9、 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 addition to standards it publishes as national standards, the CGSB produces standards to meet particular needs, in response to reque

10、sts from a variety of sources in both the public and private sectors. Both CGSB standards and national standards developed by the CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance of Standards by CGSB. CGSB standards are subject to

11、 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 brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets

12、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 Catalogue of Standards and Qualification and Certification Listings which is published annually and is available without charg

13、e 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 particular purpose. Many tests required by CGSB standards are inherently hazar

14、dous. The CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. The CGSB takes no position respecting the validity of any patent rights asserted with any item connected with this standard. Users of this stand

15、ard are expressly advised that determination of the validity of any such patent rights are entirely their own responsibility.
