17、ensions and service ratings. The workculminated and was published in 1914 under the title “1914 Brass Standard Flange Dimensions”for 150-lb and 250-lb (now Class 150 and Class 250) steam pressures.This was superseded in 1928 by the Manufacturers Standardization Society of Valves andFittings Industry

18、 (MSS) “Standard Practice” SP-2, which contained changes to provide inter-changeability with the American Cast-Iron Flange Standards for 125-lb (now Class 125) andClass 250 stream pressures. Subsequent revisions were issued in 1930 and 1936. In the latter, anew column of thickness for 300-lb (now Cl

19、ass 300) flanges was added.In the 1937 edition, illustrations and dimensions of bronze-flanged fittings were added. Thiswas edited and reprinted in 1943 to conform to the U.S. Department of Commerce, NationalBureau of Standards, Simplified Practice Recommendation R-183-42, and to the War ProductionB

20、oard Limitation Order L-252, dated January 23, 1943.In the 1946 edition, the pressuretemperature ratings were added for the Class 150 and Class 300standards and the dimensions for that reference to the Class 250 standard were omitted. LimitationOrder L-252 was canceled on April 28, 1945. The period

21、of government prohibition of manufactureand civilian use of the Class 250 standard (during the life of Order L-252) caused no hardshipon the part of either the manufacturer or the consumer, indicating that this pressure class inbronze products did not warrant being recognized as a standard.This Stan

22、dard was reviewed and reaffirmed in 1949. In October 1951, MSS ceded it to SectionalCommittee B16 on Pipe Flanges and Flanged Fittings for review and possible approval as anAmerican Standard.Following approval of the sectional committee and sponsor organizations, it was sent to theAmerican Standards

23、 Association (ASA), now the American National Standards Institute (ANSI),for approval and designation as an American Standard. This was granted on February 27, 1953.In 1961, following the organization of Subcommittee No. 11 (now Subcommittee J), the 1953edition was revised. Chief among the changes r

24、ecommended was the deletion of reference tobrass. This resulted from an action of ASTM redefining the alloys that could properly be calledbronze. Several other changes that brought the Standard up to date were also approved by theB16 Committee, with approval designation as an American Standard being

25、 granted onJuly 20, 1962.Subcommittee J, in keeping with regulations of ANSI, reviewed the Standard in 1969. Onlyminor changes were made. Among these were the presentation of pressuretemperature ratingsin tabular form, and the gasket-retaining grooves being made permissible rather than recom-mended.

26、 Final approval of the changes was granted by ANSI on January 27, 1971.A revision was undertaken in 1977, and several changes were proposed. Foremost among thesewas the addition of metric equivalents and the elimination of the optional gasket-retaininggrooves. In addition, the Standard was extensive

27、ly revised editorially. Following approvals bySubcommittee J and the Standards Committee, ANSI granted its approval on June 26, 1979.In 1982, the American National Standard Committee B16 was reorganized as anASME Committee, operating under procedures accredited by ANSI.In 1991, the scope of the Stan

28、dard was changed from bronze pipe flanges and fittings to castcopper alloy flanges and flanged fittings, and it was expanded to include class designations 150,300, 600, 900, 1500, and 2500. The 1991 edition also established U.S. Customary units as thestandard, and editorial revisions were made to im

29、prove the text. Following approval by theStandards Committee and ASME, the 1991 edition of the Standard was approved as an AmericanNational Standard by ANSI on February 1, 1991, with the new designation ASME B16.24-1991and the new title “Cast Copper Alloy Pipe Flanges and Flanged Fittings.”In 2001,

30、the Standard was revised to include Nonmandatory Appendix A, Quality SystemProgram. Editorial revisions were made for clarification. Following approval by the B16 StandardsivCommittee and the ASME Supervisory Board, the Standard was approved as an AmericanNational Standard by ANSI on October 24, 200

31、1.In the 2006 edition, metric units became the primary reference units while maintainingU.S. Customary units in either parenthetical or separate forms. Requirements for Class 400 flangeswere omitted from the Standard. In addition, several editorial revisions were made for clarity.Following approval

32、by the Standards Committee and the ASME Board, ASME B16.24-2006, CastCopper Alloy Pipe Flanges and Flanged Fittings: Classes 150, 300, 600, 900, 1500, and 2500 wasapproved as an American National Standard by ANSI on November 9, 2006.In the 2011 edition, references to ASME Standards were revised to n

33、o longer list specificedition years; the latest edition of ASME publications applies unless stated otherwise. Materialsmanufactured to other editions of the referenced ASTM standards have been permitted to beused to manufacture fittings meeting the requirements of this Standard as long as the fittin

34、gmanufacturer verifies the material meets the requirements of the referenced edition. Followingapproval by the Standards Committee and the ASME Board on PTCS, the 2011 revision wasapproved as an American National Standard by ANSI on August 9, 2011, with the designationASME B16.24-2011.In this 2016 e

35、dition, provisions have been made to revise the scope and table readings, and anew Mandatory Appendix and a new Nonmandatory Appendix have been added. Followingthe approval by the ASME B16 Standards Committee, approval as an American National Standardwas given by ANSI on September 23, 2016, with the

36、 new designation ASME B16.24-2016 andthe new title “Cast Copper Alloy Pipe Flanges, Flanged Fittings, and Valves: Classes 150, 300,600, 900, 1500, and 2500.”vASME B16 COMMITTEEStandardization of Valves, Flanges, Fittings, and Gaskets(The following is the roster of the Committee at the time of approv
