41、, Inc.25 West 43rd Street, Fourth FloorNew York, NY10036The American National Standards Institute (ANSI), Inc. is the nationally recognized coordinator of voluntary standards development in the United States through which voluntary organizations, representing virtually every technical discipline and
42、 every facet of trade and commerce, organized labor and consumer interests, establish and improve 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 sta
43、ndardization activity, and cooperates with departments and agencies of U.S. Federal, state and 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
44、nontreaty organizations such as the International Organization for Standardization (ISO) and 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 Commissio
45、n (COPANT). As such, ANSI coordinates the activities involved in the U.S. participation in these 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
46、affected by the standards has been achieved. ANSI coordination is intended to assist the voluntary 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 represen

It is the result of years of experience in the manufacturer, testing, installation, maintenance, inspection of researc

There are risks of injury to persons inherent within appliances and accessories that, if completely eliminated, would defeat the utility of the appliance or accessory. The provisions in this standard are intended to help reduce such risks while retaining the nor
49、mal operation of the appliance or accessory.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 allow compliance of press-connect metallic fittings for use in fuel gas distribution systems, the safety, construction and performance of which may exceed the various provisions specified herein.
