The group operated as a Sectional Committee (
14、laterredesignated as a Standards Committee) under the authorization of the American EngineeringStandards Committee subsequently named American Standards Association, United States ofAmerica Standards Institute, and now American National Standards Institute (ANSI). Sponsorsfor the group were the Amer
15、ican Society of Mechanical Engineers, Manufacturers StandardizationSociety of the Valve and Fittings Industry, and the Heating and Piping Contractors NationalAssociation (later the Mechanical Contractors Association of America).The American Gas Association determined that standardization of gas valv
16、es used in distribu-tion systems was desirable and needed. The A.G.A. Task Committee on Standards for Valvesand Shutoffs was formed, and development work commenced in 1958. In 1968, it was determinedthat a more acceptable document would result if approval were gained from ANSI, and to facilitatesuch
17、 action, the A.G.A. Committee became Subcommittee No. 13 of the B16 activity. This B16group was later renamed Subcommittee L, which is its current designation.The first standard developed by Subcommittee L was B16.33. The B16.38 standard was subse-quently developed to cover larger sizes of gas valve
18、s and shutoffs. Since about 1965, the increaseduse of plastic piping in gas distribution systems brought with it the need for valves and shutoffsof compatible material. To fill this need, the present standard was developed and initially appearedas ANSI B16.40-1977. Subcommittee L began review of thi
19、s document in 1982.In ANSI/ASME B16.40-1985, editorial changes were made throughout the text to bring theformat in line with the rest of the B16 series of standards and to clarify the intent of this Standard.Revisions included the addition of rules for allowable pressure at temperatures above 74F fo
20、rvalves of certain materials, updating of reference standards, and editorial changes to text andtables.In 2001, after several years and iterations, B16 Subcommittee L produced a fully reviseddocument. Among the many revisions were a new Definitions section, a new Impact Resistancesection, and a nonm
21、andatory Quality Systems Program Annex.Following approval by the B16 Standards Committee and the ASME Supervisory Board, thelast version of this Standard was approved as an American National Standard by ANSI onMarch 18, 2008.The 2013 Edition of B16.40 has updated certain material specifications and
22、includes othereditorial revisions to the text.This edition of the Standard was approved as an American National Standard by ANSI onAugust 6, 2013.All requests for interpretations or suggestions for revisions should be sent to the Secretary,B16 Committee, The American Society of Mechanical Engineers,
