3、rnment agency within the Federal Department of Supply and Services. The 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
4、interests including producers, consumers and other users, retailers, governments, educational institutions, technical. professional and trade societies. and research and tesbng organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers A
5、dvisory 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-wnting organization. The standards that it develops and offers as National Standards of Canada conform to the cnteria and procedures establish
6、ed 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 requests from a variety of sources in both the public and private sectors. Both CGSB standards and national standar
7、ds developed by the CGSB are developed in conformance with the policies descnbed 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
8、 for their improvement, whch are always webme, should be brought to the notice of the standards committees concerned. Changes to standards are issued mher as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and ame
9、ndments, and ordering instructions, will be found in the CGSB Catalogue whch is published annually and is available without charge upon request Although the intended primary applicatton of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users o
10、f the standard to judge its suitability for their particular purpose. Many tests required by CGSB standards are inherently hazardous. The CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever wrformed. The CGSB takes no
11、 position respecting the validity of any patent rights asserted with 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. Further information on the CGSB and its service
