2、HE STANDARDS The Standards Council of Canada is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement af voluntary standardization in the national interest. The principal objects of the C
3、ouncil are to foster and promote voluntary standardization as a means of advancing the national economy, benefitting the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international co-operation in the fi
4、eld of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a batance
5、of representation of producers, users, COUNCIL OF CANADA consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a staqdard which is capabte of making a significant and timely contribution-to the national interest. Approval of a Standard as a Nation
6、al Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards-writing organization. Those
7、 who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving Nati
8、onal Standards of Canada rests with the Standards Council of Canada 45 QConnor Street, Suite 1200, OTTAWA, Ontario. CANADA KIP 6N7 THE CANADIAN GAS ASSOCIATION The Canadian Gas Association, which represents all segments of the natural gas industry, has been accredited by the Standards Counct of Cana
9、da to prepare National Standards of Canada in the area of equipment for use with natural gas and propane. This Standard has been accepted by the Standards Committee, IGAC and SAC. This Standard is intended to be used within the scope of the standard CGA, founded in 1907, represents distributors, tra
10、nsmission companies, producers, pipeline contractors, manufacturers, and allied service organizations. CGA set up a standards writing, inspection, and certification programme in the mid-1950s at a time when natural gas service was being extended to Eastern Canada and the West Coast. The standards pr
11、ogramme now embraces 90 standards for gas appliances and accessories. Committees that write the standards include representation from all interests and are so constituted that no one interest may dominate. The interests represented include consumers, manufacturers, utilities, governmental inspection
12、 authorities, and certification organizations. Standards are prepared using the consensus principle with effort applied to reconcile differing opinions. Government inspection authoritres having jurisdictiori also ballot on the standards as members of the Interprovincial Gas Advisory Council (IGAC).
13、The CGA Standards Advisory Committee (SAC) reviews committee structures and procedures to determine that a standard meets !he criteria of the Standards Council of Canada. by the manufacturing sector. by those applying the equipment, or those responsible for its proper application. tt is the responsi
14、bility of the user to determine in each case that the Standard is suitable for the specific application. The Standards Committee and IGAC normally stipulate an effective date for the Standard, delayed sufficiently to permit suppliers to make adjustments. CGA Approvals, incorporated 1993, operates a
15、certification programme for fuel-fired products which is accepted by all Canadian inspection authorities and accredited by the Standards Council of Canada. In addition, through the Canadian Gas Research Institute (CGRI), the gas industry is pursuing the improvement of equipment and the development o
16、f new products. Data from these projects is available to Standards Committees for review and consideration. Recommendations for new standards and revisions to existing standards may come from any source. These suggestians should be addressed to the Standards Department of CGA Approvals. Published by
