It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certif
7、ication activities.CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and
8、 federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee
9、work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs stan

24、rove the some 10,000 national consensus standards currently approved as American National Standards.ANSI provides that the interests of the public may have appropriate participation and representation in standardization activity, and cooperates with departments and agencies of U.S. Federal, state an
25、d local governments in achieving compatibility between government codes and standards and the voluntary standards of industry and commerce.ANSI represents the interests of the United States in international nontreaty organizations such as the International Organization for Standardization (ISO) and
26、the International Electrotechnical Commission (IEC). The Institute maintains close ties with regional organizations such as the Pacific Area Standards Congress (PASC) and the Pan American Standards Commission (COPANT). As such, ANSI coordinates the activities involved in the U.S. participation in th
27、ese groups.ANSI approval of standards is intended to verify that the principles of openness and due process have been followed in the approval procedure and that a consensus of those directly and materially affected by the standards has been achieved. ANSI coordination is intended to assist the volu
28、ntary system to ensure that national standards needs are identified and met with a set of standards that are without conflict or unnecessary duplication in their requirements.PrefaceThis publication represents a basic standard for safe operation, substantial and durable construction, and acceptable
29、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 gas. There
30、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 considered i
31、n 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 preparation
32、, 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 East Pleasant V
33、alley Road, Cleveland, Ohio 44131, or the Chairman of the CSA Standards Steering Committee on Gas Burning Appliances and Related Accessories, 5060 Sprectrum Way, Suite 100; Mississauga, Ontario, Canada L4W 5N6.Safe and satisfactory operation of a connectors for outdoor gas appliances and manufacture
34、d homes depends to a great extent upon its proper installation. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54; the Natural Gas and Propane Installation Code, CSA B149.1; the (U.S.) Manufactured Home Construction and Safety Standard, Title 2
35、4 CFR, Part 3280, or when such standard is not applicable, the Standard for Manufactured Home Installations, Sites and Communities, ANSI/NFPA 501A, or the Standard for Mobile Homes, CAN/CSA-Z240 MH Series; or the manufacturers installation instructions and local municipal codes.Users of this America
36、n 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, state or local level. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a
37、 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 AND BY THOSE APPLYING THE EQUIPMENT AND BY THOSE RESPONSIBLE FOR ITS PROPER INSTALLATION. IT IS THE RESPONSIBILITY OF THES
38、E 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 revised or withdrawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken
39、 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 on all standards by calling or writing the American National Standards Institute, Inc., 25 West 43rd Street, Fourth Floor,
40、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 the date by which all products certified by that organization should comply with this standard. In Canada the Interprovincial
41、 Gas Advisory Council normally stipulates an effective date for the standard, delayed sufficiently to permit suppliers (manufacturers) to make adjustments.iiHistory Of The Development Of The Standard For Connectors For Outdoor Gas Appliances And Manufactured Homes(This History is informative and is
42、not part of the standard.)With the onset of the Free Trade Agreement between the United States and Canada on 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 industr
43、ial applications. It was believed that the elimination of the differences between the standards would remove 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 als
44、o seen as a step toward harmonization with international standards.A draft harmonized standard for connectors for outdoor appliances and 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
45、reviewed, by letter ballot, the first draft harmonized connectors for outdoor appliances and manufactured homes standard based on current 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
46、 Connection of Fixed Appliances for Outdoor Installation, Park Trailers and Manufactured (Mobile) Homes to the Gas Supply, A.G.A. 3-87 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 199
47、8. At its July 14, 1999 meeting, following reconsideration and modifications in light of comments received on the proposed draft standard, the joint subcommittee recommended the proposed draft to the Accredited Standards Committee Z21/83 and the CSA Technical Committee for approval.The proposed draf
48、t of the harmonized standard for connectors for outdoor appliances and manufactured homes, as modified by the joint subcommittee, was approved by the Z21/83 Committee on April 13, 2000, and by the CSA Technical Committee by letter ballot dated March 24, 2000.The first edition of the harmonized Ameri
49、can National Standard/CSA Standard for Connectors for Outdoor Appliances and Manufactured Homes was approved by the Canadian Interprovincial Gas Advisory Council on February 15, 2001 and by the American National Standards Institute, Inc., on November 27, 2001.This, the second edition of the harmonized Standard for Connectors for Outdoor Gas Appliances and Manufactured Homes was approved by the IGAC on January 4, 2006, and by ANSI on May 18, 2007.The previous edition of the Sta
