Provided by IHS under license with CSA/AM Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-PrefaceThis publication represents a basic standard for safe operation, substantial and durable construction, and

31、 acceptable performance of connectors for outdoor gas appliances and manufactured homes. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on connectors for outdoor gas appliances and manufactured homes designed for utilization of

32、 gas. There are risks of injury to persons inherent in some appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to reduce such risks while retaining the normal operation of the appliance.Nothing in this standard is to be

33、considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of connectors for gas appliances and manufactured homes, the construction and performance of which may exceed the various provisions specified herein. In its

34、 preparation, full recognition has been given to possibilities of improvement through ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations should be forwarded to the Chairman of Accredited Standards Committee Z21/83, 8501 Eas

44、icense from IHS-,-,-iiHistory Of The Development Of The Standard For Connectors For Outdoor Gas Appliances And Manufactured Homes(This History is informative and is not part of the standard.)With the onset of the Free Trade Agreement between the United States and Canada on January 2, 1988, significa

45、nt attention was given to the harmonization of the United States and Canadian safety standards addressing gas-fired equipment for residential, commercial and industrial applications. It was believed that the elimination of the differences between the standards would remove potential trade barriers a

46、nd provide an atmosphere in which North American manufacturers could market more freely in the United States and Canada. The harmonization of these standards was also seen as a step toward harmonization with international standards.A draft harmonized standard for connectors for outdoor appliances an

47、d manufactured homes was prepared by the subcommittee memebers and CSA staff. On September 15, 1998, the Z21/CSA Joint Subcommittee on Connectors for Gas Appliances reviewed, by letter ballot, the first draft harmonized connectors for outdoor appliances and manufactured homes standard based on curre

48、nt coverage from the American National Standard/CGA Standard for Connectors for Gas Appliances, Z21.24/CGA 6.10-1997, and the U.S. Requirement for Gas Connectors for Connection of Fixed Appliances for Outdoor Installation, Park Trailers and Manufactured (Mobile) Homes to the Gas Supply, A.G.A. 3-87

49、and CSA Standard, CSA 6.27.The September letter ballot was approved by the joint subcommittee to distribute the draft standard for review and comment in December 1998. At its July 14, 1999 meeting, following reconsideration and modifications in light of comments received on the proposed draft standard, the joint subcommittee recommend
