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 standard

4、s 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 CGSB. are developed in conformanc

5、e 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 government or an industry for a material, a product, or a service. A specification also states the procedures to de

6、termine 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 ail vital interests or consensus approval. CGSB specifications are subject to review and revis

7、ion at any he, so as to ensure that they keep abreast of technological progress. Suggestions for their improvemenf which are always welcome, should be brought to the notice of the committee concerned. Changes to SpeCitications are issueij either as separate amendment sheets or in new editions of spe

8、cifications. An up-todate listing of CGSB specifications, including details on latest issues and amendments, and ordering instructions, WU be found in the CGSB Catalogue, which is published annualiy and is available without charge upon request. Aithough the intended primary application of this speci

9、fication is stated 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 inherently hazardous. CGSB neither assumes nor accepts any responsibilit

10、y for any injury or damage that may occur during or as the result of tests, wherever performed.
