The CCSB is engaged in the production of vol

6、untary 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, consumers and other users, retailers, governments, educational institutions, tech

7、 nical, professional and trade societies, and research and test- ing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. The CCSB has been accredited by the S

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

9、 standards, the CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CCSB standards and national standards developed by the CCSB are developed in conformance with the policies described in the Policy Manual f

10、or the Development and Maintenance of Standards by CGSB. CCSB 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 al- ways welcome, should be brought to the notice of the stand- ards

11、committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards.
