23、Inc. is the nationally recognized coordinator of voluntary standards development in the United States through which voluntary organizations, representing virtually every technical discipline and every facet of trade and commerce, organized labor and consumer interests, establish and improve the some
24、 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 and local gover
25、nments 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 the Internati
26、onal 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 these groups.AN
27、SI 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 voluntary system
28、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 performance o
29、f a line pressure regulator. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on line pressure regulators. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of th
30、e 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 contains. It is designed to al
31、low compliance of a line pressure regulator, 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 place, revisions may become
32、necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the CSA America, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6.Safe and satisfactory opera
33、tion of line pressure regulators depends to a great extent upon its proper installation, use, and maintenance. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1.Users of this American
34、 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 levels. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a
35、 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
36、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
37、 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,
38、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.iiHistory Of The Development O
39、f The Standard For Line Pressure Regulators(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, significant attention was given to the harmonization of the United States and Canadian safety s
40、tandards 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 and provide an atmosphere in which North American manufacturers could market more freel
41、y in the United States and Canada. The harmonization of these standards was also seen as a step toward harmonization with international standards.With the formation of joint subcommittees, a Canadian Gas Association Standards Steering Committee on Gas Burning Appliances and Related Accessories was e
42、stablished to parallel Accredited Standards Committees Z21 and Z83, and to support the formation of joint subcommittees. In accordance with American National Standards Institute procedures for joint subcommittees, operating procedures were developed and subsequently approved by ANSI on April 1, 1993
43、.During its July 12-13, 1994 meeting, the Joint Automatic Gas Controls Subcommittee adopted the harmonized draft standard for line pressure regulators, Z21.80 CSA 6.22, for distribution for review and comment. The harmonized draft standard for line pressure regulators was based on American National
44、Standard for Gas Appliance Pressure Regulators, ANSI Z21.18-1993.During its August 15, 1995 meeting, the Automatic Gas Controls Subcommittee (formerly the Automatic Gas Controls Subcommittee and the Thermostat and Gas Ignition Systems Subcommittee) reconsidered the proposed draft harmonized standard
45、 in light of comments received. The proposed harmonized standard was revised and recommended to Accredited Standards Committee Z21 and the Canadian Standards Steering Committee for approval.The Z21 Committee approved the proposed harmonized standard by letter ballot dated January 31, 1996, for submi
46、ttal to the American National Standards Institute, Inc. The Canadian Standards Steering Committee approved the proposed harmonized standard by letter ballot dated May 8, 1996, for submittal to the Interprovincial Gas Advisory Council.The Interprovincial Gas Advisory Council (IGAC) approved the propo
47、sed harmonized standard by letter ballot dated June 28, 1996. This, the first edition of the harmonized standard for line pressure regulators was approved as American National Standard by the American National Standards Institute, Inc. (ANSI) on March 13, 1997.The second edition of the harmonized li
48、ne pressure regulator standard was approved by the IGAC on August 25, 2003, and ANSI on November 14, 2002.This the third edition of the line pressure regulator standard was approved by the IGAC on April 1, 2011and by ANSI on November 16, 2011.Previous editions of the harmonized line pressure regulat
