2、Works and Government Services Canada. 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 interests including producers, con

3、sumers 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. CGSB has been accredited by the Standards Counci

4、l of Canada as a national standards-development 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

5、of Canada, 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 CGSB national standards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for

6、 the Development and Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their improvement, which are alway

7、s 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, and ordering instructions

8、, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ongc-cgsb along with more information about CGSB products and services. 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

9、 the standard to judge its suitability for their particular purpose. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyo

10、ne using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that

11、 may occur during or as the result of tests, wherever performed. Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Users of this standard are

12、 expressly advised that determination of the validity of any such patent rights is entirely their own responsibility. Language In this Standard, shall states a mandatory requirement, should expresses a recommendation and may is used to express an option or that which is permissible within the limits

13、 of this Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Annexes are designated normative (mandatory) or informative (non-mandatory) to define t

14、heir application. Further information on CGSB and its services and standards may be obtained from: The Manager Standards Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is

15、 composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health

16、and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public

17、, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effecti

18、ve participation by concerned interests; respect for diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the st

19、andards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC appr

20、oval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of ge

21、neral interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to the subject at hand. NSCs are intended to make a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are encouraged to u

22、se NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard. The responsibility for approving standards as NSCs rests with: Standards Council of Canada 270 Albert Street, Suite 200 Ottawa, Ontario K1P 6N7,
