1、NATIONAL STANDARD OF CANADA DOMESTIC GAS RANGES Effective Date - May 1980 This Standard is a revised and combined edition of the former CGA 1.1-1976 and eGA 1.2-1976 Prepared by Canadian Gas Association Approved by Standards Council of Canada Published November 1981 Copyright Canadian Gas Associatio

2、n - 1981 CAN1-1.1-M81 THE STANDARDS COUNCIL OF CANADA 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 of voluntary standardization in the national

3、 interest. The principal objects of the Council 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 furthe

4、ring international co-operation in the field 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 th

5、e greatest practicable extent, a balance of representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest. Approval of

6、 a Standard as a National 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-writ

7、ing organization. Those 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 responsibi

8、lity for approving National Standards of Canada rests with the Standards Council of Canada 45 OConnor Street, Suite 1200, OTTAWA, Ontario. CANADA K1P 6N7 THE CANADIAN GAS ASSOCIATION The Canadian Gas Association, which represents all segments of the natural gas industry, has been accredited by the S

9、tandards Council of Canada to prepare National Standards of Canada in the area of equipment for use with natural gas and propane. CGA, founded in 1907, represents distributors, transmission companies, producers, pipeline contractors, manufacturers, and allied service organizations. CGA set up a stan

10、dards 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 programme now embraces more than 90 standards for gas appliances and accessories. Committees that write the standards incl

11、ude representation from all interests and are so constituted that no one interest may dominate. The interests represented include consumers, manufacturers, utilities, governmental inspection authorities, and certification organizations. Standards are prepared using the consensus principle with effor

12、t applied to reconcile differing opinions. Government inspection authorities having jurisdiction also ballot on the standards as members of the Interprovincial Gas Advisory Council (IGAC). The CGA Standards Advisory Committee (SAC) reviews committee structures and procedures to determine that a stan

13、dard meets the criteria of the Standards Council of Canada. 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 by the manufacturing sector, by those applying the eqUipment, or those responsible for its prope

14、r application. It is the responsibility 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 Approval

15、s, incorporated 1993, operates a 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 o

16、f equipment and the development of 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 suggestions should be addressed to the Standards Departme
