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 acceptable performance of a connector for
31、gas appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on connectors for gas appliances designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would
32、defeat the utility of the appliance. The provisions in this standard are intended to help reduce such risks while retaining the normal operation of the appliance.Nothing in this standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contai
33、ns. It is designed to allow compliance of connectors for gas appliances, the safety construction and performance of which may exceed the various provisions specified herein. In its preparation, recognition has been given to possibilities of improvement through ingenuity of design. As progress takes
34、place, revisions may become necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the Chairman of Accredited Standards Committee Z21/83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman of CSA Technical Committee on Gas Appliances an
35、d Related Accessories, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.Safe and satisfactory operation of a connector for gas appliances depends to a great extent upon its proper installation, use and maintenance. It should be installed, as applicable, in accordance with the Natio
36、nal Fuel Gas Code, ANSI Z223.1/NFPA 54; and the Natural Gas and Propane Installation Code, CSA B149.1.Users of this American National Standard/CSA Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, Territorial, Provincial, sta
37、te or local level. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this standard, the Federal, Territorial, Provincial, state or local regulation should be followed.THIS STANDARD IS INTENDED TO BE USED BY THE MANUFACTURING SECTOR
38、 AND BY THOSE APPLYING THE EQUIPMENT AND BY THOSE RESPONSIBLE FOR ITS PROPER INSTALLATION. IT IS THE RESPONSIBILITY OF THESE USERS TO DETERMINE THAT IN EACH CASE THIS STANDARD IS SUITABLE FOR AND APPLICABLE TO THE SPECIFIC USE THEY INTEND.CAUTION NOTICE: This American National Standard may be revise
39、d or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken to reaffirm, revise or withdraw this standard no later than five (5) years from the date of approval. Purchasers of American National Standards may receive current information
40、on all standards by calling or writing the American National Standards Institute, Inc., 25 West 43rd Street, Fourth Floor, New York, N.Y. 10036, (212) 642-4900.EFFECTIVE DATE: An organization using this standard for product evaluation as a part of its certification program will normally establish th
41、e date by which all products certified by that organization should comply with this standard. In Canada the Standards Committee and the Interprovincial Gas Advisory Council normally stipulate an effective date for the standard.Copyright CSA America, Inc.

43、n January 2, 1988, significant 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 remov
44、e potential trade barriers and 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 connecto
45、rs for moveable gas appliances was prepared for review by the Z21/CGA Joint Connector Subcommittee. The draft harmonized standard for connectors for gas appliances is based on the American National Standard for Connectors for Gas Appliances (Z21.24-1993 and Z21.24a-1993), the standard American Natio
46、nal Standard for Flexible Connectors of Other than All-Metal Construction for Gas Appliances (Z21.45-1992, Z21.45a-1993 and Z21.45b-1993), and the National Standard of Canada for Connectors for Gas-Appliances (CAN/CGA-6.10-M88). At its September 20, 1994 meeting, the Z21/CGA joint Connector Subcommi
47、ttee considered and modified the proposed harmonized draft standard and agreed to distribute it for industry review during April 1995.With the formation of joint subcommittees, a Canadian Gas Association Standards Steering Committee on Gas Burning Appliances and Related Accessories was established t
48、o parallel Accredited Standards Committees Z21 and Z83, and to support the formation of joint subcommittees. Operating procedures, in accordance with American National StandardsInstitute procedures, for joint subcommittees were developed and subsequently approved by ANSI on April 1, 1993.Following r
49、econsideration and modification of the proposed draft standard for connectors for gas appliances, in light of comments received, the joint connector subcommittee, at its November 16, 1995 meeting, recommended the proposed draft to the Z21 Committee and the CGA Standards Steering Committee for approval.The first edition of the harmonize
