2、ense from IHS-,-,- = 28?74650 002bbL2 73T The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed is a government agency within the Federal Department of Supply and Services. CGSB is engaged in the production of voluntary standards in a wide range of subjec
3、t 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, retailers, governments, educational institutions, technical, professional and trade societies, a
4、nd research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Minister?s Advisory Council on CGSB reviews the results of the consensus process. CGSB has been accredited by the Standards Council of Canada as a national standard
5、s-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 addition to standards it publishes as national standards, CGSB produces standards to meet parti
6、cular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance of Standards by CGSB.
7、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 brought to the notice of the standards committees concerned. Changes to standards are issued either
8、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 Catalogue, which is published annually and is available without charge upon request. Although
9、 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 hazardous. CGSB neither assum
10、es 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 with any item connected with this standard. Users of this standard are expressly advised that d
11、etermination of the validity of any such patent rights are entirely their own responsibility. Further information on CGSB and its services and standards may be obtained from: The STANDARDS COUNCIL OF CANADA is the Co-ordinating body of the National Standards System, a federation of independent, auto
12、nomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety
13、and welfare of the public, assisting and protecting the consumer, facilitating domestic and intemational trade, and furthering international co-operation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which re
14、flects 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 others with relevant interests, as may be appropriate to the subject in hand. It nor
15、mally 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 indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not re
16、fer 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 Standards of Canada whenever practicable. These standards are subject to periodic review
17、; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with the: * Standards Council of Canada 45 O?Connor Street Suite 1200 Ottawa, Ontario KIP 6N7 by Fax by Mail -3 Publications
