FOREWORD

The development of the first Bronze Flanged Standard began in 1910 to eliminate the confusion prevailing in the trade with respect to bronze flange dimensions and service ratings. The work culminated 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This was superseded in 1928 by the Manufacturers Standardization Society of Valves and Fittings Industry (MSS) “Standard Practice” SP-2, which contained changes to provide inter-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) and Class 250 stream pressures. Subsequent revisions were issued in 1930 and 1936. In the latter, a new column of thickness for 300-lb (now Class 300) flanges was added.

In the 1937 edition, illustrations and dimensions of bronze-flanged fittings were added. This was edited and reprinted in 1943 to conform to the U.S. Department of Commerce, National Bureau of Standards, Simplified Practice Recommendation R-183-42, and to the War Production Board Limitation Order L-252, dated January 23, 1943.

In the 1946 edition, the pressure–temperature ratings were added for the Class 150 and Class 300 standards and the dimensions for that reference to the Class 250 standard were omitted. Limitation Order L-252 was canceled on April 28, 1945. The period of government prohibition of manufacture and civilian use of the Class 250 standard (during the life of Order L-252) caused no hardship on the part of either the manufacturer or the consumer, indicating that this pressure class in bronze products did not warrant being recognized as a standard.

This Standard was reviewed and reaffirmed in 1949. In October 1951, MSS ceded it to Sectional Committee B16 on Pipe Flanges and Flanged Fittings for review and possible approval as an American Standard.

Following approval of the sectional committee and sponsor organizations, it was sent to the American Standards 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 1953 edition was revised. Chief among the changes recommended was the deletion of reference to brass. This resulted from an action of ASTM redefining the alloys that could properly be called bronze. Several other changes that brought the Standard up to date were also approved by the B16 Committee, with approval designation as an American Standard being granted on

July 20, 1962.

Subcommittee J, in keeping with regulations of ANSI, reviewed the Standard in 1969. Only minor changes were made. Among these were the presentation of pressure–temperature ratings in tabular form, and the gasket-retaining grooves being made permissible rather than recom- mended. 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 these was the addition of metric equivalents and the elimination of the optional gasket-retaining grooves. In addition, the Standard was extensively revised editorially. Following approvals by Subcommittee J and the Standards Committee, ANSI granted its approval on June 26, 1979.

In 1982, the American National Standard Committee B16 was reorganized as an ASME Committee, operating under procedures accredited by ANSI.

In 1991, the scope of the Standard was changed from bronze pipe flanges and fittings to cast copper 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 the standard, and editorial revisions were made to improve the text. Following approval by the Standards Committee and ASME, the 1991 edition of the Standard was approved as an American National Standard by ANSI on February 1, 1991, with the new designation ASME B16.24-1991 and the new title “Cast Copper Alloy Pipe Flanges and Flanged Fittings.”

In 2001, the Standard was revised to include Nonmandatory Appendix A, Quality System Program. Editorial revisions were made for clarification. Following approval by the B16 Standards

Committee and the ASME Supervisory Board, the Standard was approved as an American National Standard by ANSI on October 24, 2001.

In the 2006 edition, metric units became the primary reference units while maintaining

U.S. Customary units in either parenthetical or separate forms. Requirements for Class 400 flanges were omitted from the Standard. In addition, several editorial revisions were made for clarity. Following approval by the Standards Committee and the ASME Board, ASME B16.24-2006, Cast Copper Alloy Pipe Flanges and Flanged Fittings: Classes 150, 300, 600, 900, 1500, and 2500 was approved as an American National Standard by ANSI on November 9, 2006.

In the 2011 edition, references to ASME Standards were revised to no longer list specific edition years; the latest edition of ASME publications applies unless stated otherwise. Materials manufactured to other editions of the referenced ASTM standards have been permitted to be used to manufacture fittings meeting the requirements of this Standard as long as the fitting manufacturer verifies the material meets the requirements of the referenced edition. Following approval by the Standards Committee and the ASME Board on PTCS, the 2011 revision was approved as an American National Standard by ANSI on August 9, 2011, with the designation ASME B16.24-2011.

In this 2016 edition, provisions have been made to revise the scope and table readings, and a new Mandatory Appendix and a new Nonmandatory Appendix have been added. Following the approval by the ASME B16 Standards Committee, approval as an American National Standard was given by ANSI on September 23, 2016, with the new designation ASME B16.24-2016 and the new title “Cast Copper Alloy Pipe Flanges, Flanged Fittings, and Valves: Classes 150, 300, 600, 900, 1500, and 2500.”
