3、vate and public sectors. 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 this purpose by the Standards Council of

4、 Canada. in addition to standards it publishes as national standards, CGSB produces standards and specification to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. CGSB standards and specifications, and national standards developed by C

5、GSB, are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance of Standards by CGSB. CGSB specifications are developed to state the particular requirements of a governent or an industry for a material, a product, or a service. A specification a

6、lso states the procedures to determine if the requirements have been met. Unlike a CGSB standard, a CGSB specification may lack any one or any combination of the following factors: broad application, committee balance, representation of all vital interests or consensus approval. CGSB specifications

7、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 committee concerned. Changes to specifications are issued either as separate amendment

8、 sheets or in new editions of specifications. An up-to-date listing of CGSB specifications, 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 the intend

9、ed primary application of this specification is state in its Scope, it is important to note that it remains the responsibility of the users of the specification to judge its suitability for their particular purpose. Many tests required by CGSB specifications are inherentiy hazardous. CGSB neither as

10、sumes 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 specification. Users of this specification are expressly a
