2、ment agency within the Federal Department of Supply 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 intere

3、sts including producers, consumers and other users, 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 Adviso

4、ry Council on CGSB reviews the results of the consensus proms. 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 th

5、is purpose by the Standards Council of Canada. in addition to standards it publishes as national standards. 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 standards developed

6、 by 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 any time, so as to ensure that they keep abreast of technological progress. Suggestions for their impr

7、ovement, 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 or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, a

8、nd ordering instniaions. will be found in the CGSB 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 st

9、andard to judge its suitability for their particular 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 respe

10、cting 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 CGSB and its services and standards may

Canada KIA 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 de

12、velopment 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 and welfare of the public, assisting and protecting

13、 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 reflects a reasonable agreement among the views of a

14、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 normally is a standard that is capable of making a sig

15、nificant 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 proCCdures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard, this

16、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; therefore, users are cautioned to obtain the lates

17、t edition from the organization preparing the standard. The responsibility for approving National Standards of Canada rests with the: Standards Council of Canada 45 OConnor Street Suite 1200 Ottawa, Ontario K1P 6N7 (Canaah only) by Fax - (613) 941-8705 by Mail - CGSB Sales Centre Ottawa, Canada KIA
