Copyright © 2002, National Fire Protection Association, All Rights Reserved This edition of NFPA 24, Standard for the Installation of Private Fire Service Mains and Their Appurtenances, was prepared by the Technical Committee on Private Water Supply Piping Systems, released bythe Technical Correlating Committee on Automatic Sprinkler Systems, and acted on by NFPA at its May Association Technical Meeting held May 19–23, 2002, in Minneapolis, MN. It was issued by the Standards Council on July 19, 2002, with an effective date of August 8, 2002, and supersedes all previous editions. This edition of NFPA 24 was approved as an American National Standard on July 19, 2002.Origin and Development of NFPA 24 In 1903, the NFPA Committee on Hose and Hydrants first presented Specifications for Mill Yard Hose Houses, taken substantially from a standard published by the Eastern Factory Insurance Association. This text was revised and adopted in 1904. The NFPA Committee on Field Practice amended the Specifications in 1926, published as NFPA 25. In 1925, the Committee on FieldPractice prepared a Standard on Outside Protection, Private Underground Piping Systems Supplying Water for Fire Extinguishment, which was adopted by NFPA. It was largely taken from the 1920 edition of the NFPA Automatic Sprinkler Standard, Section M on Underground Pipes and Fittings. In September 1931, a revision was made, with the resulting standard designated as NFPA 24. In the 1981 edition thetitle was changed from Standard for Outside Protection to Standard for the Installation of Private Fire Service Mains and Their Appurtenances. In 1953, on recommendation of the Committee on Standpipes and Outside Protection, the two standards (NFPA 24 and NFPA 25) were completely revised and adopted as NFPA 24. Amendments were made leading to separate editions in 1955, 1959, 1962, 1963, 1965, 1966,1968, 1969, 1970, 1973, 1977, 1981, 1983, and 1987. The 1992 edition included amendments to further delineate the point at which the water supply stops and the fixed fire protection system begins. Minor changes were made

Revisions were made to provide additional information regarding listing requirements, signage, valves, valve supervision, hydrant outlets, system attachments, piping materials, and thrust blocks.
