The development of a standard for brass fittings for flared copper water tubes was initiated by a subcommittee of the Copper Tube and Fitting Manufacturers Standardization Committee in the year 1929. When a general agreement had been reached, the draft of the proposed standard was submitted to Sectional Committee A40 on Minimum Requirements for Plumbing and Standardization of Plumbing Equipment, of the American Standards Association. Sectional Committee A40 was jointly sponsored by the American Society of Sanitary Engineering and The American Society of Mechanical Engineers.

Final ASA approval and designation as an American Standard, ASA A40.2-1936, was granted January 20, 1936.

The Standard remained unchanged and without reaffirmation until 1955 when this activity was transferred from Sectional Committee A40 to Sectional Committee B16 on Standardization of Pipe Flanges and Fittings, under the sponsorship of The American Society of Mechanical Engineers, the Mechanical Contractors Association of America, Inc., and the Manufacturers Standardization Society of the Valve and Fittings Industry.

Subcommittee No. 9 B16 on Solder-Joint Fittings was instructed to develop a revised standard. The revised draft of this standard was submitted to industry for criticism and comment. The final draft was approved by Sectional Committee B16 and its sponsors by letter ballot.

ASA approval and designation as ASA B16.26-1958 was granted on February 12, 1958. Beginning in 965, consideration was given to reviewing the standard in light of progress made in the production of these fittings. Subcommittee No. 9 completed its work by recommending the updating of referenced standards and thread specifications, and including additional material. Following approval by the USA Standards Committee and Sponsors, the revision was approved by the new USA Standards Institute on April 21, 1967.

In 1982 American National Standards Committee B16was reorganized as an ASME Committee operating under procedures accredited by ANSI. In this 1988 edition, metric units have been omitted and references to other standards have been updated. Following approval by the B16 Main Committee and the ASME Supervisory Board, and after public review, this Standard was approved as an American National Standard by ANSI on August 23,1988.

Requests for interpretations or suggestions for revisions should be sent to the Secretary, B16 committee, The American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017.
