31、s Association (ASA) Sectional Committee A40 on Minimum Requirements for Plumbing and Standardization of Plumbing Equipment, organized in August 1928, under the procedures of the ASA. Subcommittee No. 11 on Solder-Joint Fittings for Tubing was appointed in October 1936. At its first meeting, the Subc

32、ommittee was informed of the investigation of solder joints being carried out by the National Bureau of Standards (now the National Institute of Standards and Technology). It was decided that the Subcommittees scope should cover only solder fittings for use in plumbing. A subgroup was appointed to s

33、tudy the tolerances of commercial fittings, including depth of bore, laying lengths, and diameters of copper tube. A draft standard was sent to the Subcommittee in February 1939; a revision was distributed in August to selected organizations and individuals for review. A new Subcommittee draft dated

34、 April 1940 was approved by Sectional Committee A40, the sponsor, and following ASA approval, was published in January 1941 as ASA A40.3-1941. In 1949, the sponsors agreed to transfer responsibility for solder joint fittings to Sectional Committee B16 of ASA, because the fittings were being used in

35、many applications other than plumbing. Subcommittee 9, Standardization of Solder Joint Fittings was established and charged with developing a revised standard. An April 1949 draft was distributed for industry review, resulting in recommended changes. A new draft was approved by Sectional Committee B

36、16, sponsor organizations, and ASA, and published as ASA B16.18-1950. Work began in 1958 on a revision, including improvements in language. It was approved by B16, sponsor organizations, and ASA, and published as ASA B16.18-1963. Starting in 1969, a comprehensive review resulted in revisions to clar

37、ify the text and to permit additional material. Final approval was granted by the American National Standards Institute ANSI (formerly ASA) on March 2, 1972, for publication as ANSI B16.18-1972. The Subcommittee, now Subcommittee I, began a new revision on 1974, resulting in the addition of supply a

38、nd return tees, baseboard tees, and flush bushings, as well as metrication, and change of “bronze” to “copper alloy. ” The draft that was finally approved was published as ANSI B16.18-1978. In 1982, American National Standards Committee B16 became the ASME B16 Standards Committee, operating with the

39、 same scope under ASME procedures accredited by ANSI. Subsequently, Subcommittee I merged with Subcommittee J, which had a related scope. A general review was then started, resulting in a number of editorial changes and a few pictorial corrections. Following approval by Subcommittee J, the B16 Stand

40、ards Committee, and ASME, ANSI granted approval on January 13, 1984, for publication of the standard as ANSI B16.18-1984. The standard was reaffirmed in 1994 with no change. The 2001 edition of B16.18 contained a defined bursting strength, defined standard gaging method of threaded ends, and other c

41、larifications and updates to text. Following approval by the Standards Committee and ASME, the edition was approved as an American National Standard on October 17, 2001, with the designation ASME B16.18-2001. In the 2012 edition, new copper alloys were added for potable water applications. Also, ref

42、erences to ASME standards were revised to no longer list specific edition years; the latest edition of ASME publications applied, unless stated other- wise. Materials manufactured to other editions of the referenced ASTM standards were permitted to be used to manu- facture fittings meeting the requi

43、rements of this Standard as long as the fitting manufacturer verified that the material met the requirements of the referenced edition. Following approval by the B16 Standards Committee and the ASME Board on Pressure Technology Codes and Standards, the 2012 edition was approved as an American Nation

44、al Standard by ANSI on January 13, 2012, with the new designation ASME B16.18-2012. In this 2018 edition, the Material section has been revised to add low-lead requirements for castings intended for use in potable water systems. Following approval by the ASME B16 Standards Committee, ASME B16.18-201

45、8 was approved as an American National Standard by ANSI on February 16, 2018. vASME B16 COMMITTEE Standardization of Valves, Flanges, Fittings, and Gaskets (The following is the roster of the Committee at the time of approval of this Standard.)
