The user of this standard is responsible for judging its suitability for his
3、particular purpose or application. The Canadian General Standards Board develops voluntary standards through standards committees and the consensus process. All relevant interests are invited to be represented on the standards committees, including producers, consumers and other users, retailers, go
4、vernments, educational institutions, technical, professional and trade societies and research and testing organizations. CGSB is recognized by the Standards Council of Canada as a national standards-writing organization. CGSB produces standards to meet particular needs in response to requests from b
5、oth the public and the private sectors. CGSB standards are subject to periodic review to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are alwavs welcome, are brought to the notice of the standards committees concerned. Changes to standards are iss
