3、 BOARD (CGSB), under whose auspices this standard has been developed is a government 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
4、process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, tech- nical, professional and trade societies, and research and test- ing organizations. Any given standard is dev
5、eloped 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 that it develops and of
6、fers 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 requests from a variety of so
7、urces 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 review and revision at
8、any time, so as to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are al- ways welcome, should be brought to the notice of the stand- ards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions o
9、f 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 Qualified Products Lists which is published annually and is available without charge upon request. Although the intended
10、 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 suitabil- ity for their particular purpose. Many tests required by CGSB standards are inherently hazard- ous. The CGSB neither assumes no
11、r accepts any responsibility for any injury or damage that may oc!cur 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 standard are expressly advised that d
