30、llation of Foam-Water Sprinkler and Foam-WaterSpray Systems, was prepared by the Technical Committee on Foam-Water Sprinklers and re-leased by the Correlating Committee on Automatic Sprinkler Systems. It was issued by theStandards Council on November 11, 2014, with an effective date of December 1, 2
31、014, andsupersedes all previous editions.This edition of NFPA 16 was approved as an American National Standard on December 1,2014.Origin and Development of NFPA 16The first standard involving foam-water sprinkler systems was published in 1954 by theNational Board of Fire Underwriters (now American I
32、nsurance Association) and was titledStandard for Combined Foam- and Water-Spray Systems. The NFPA Technical Committee on Foam-Water Sprinklers was established in 1959 with assistance from the NBFU. The first edition ofthis standard was published in 1962.Various updates to the standard were completed
33、 in 1968, 1974, 1988, and 1990. Changeswere made to recognize the use of new foam concentrates and to improve the language andformat of the document.The 1995 edition included clarification of the scope of the standard, improvements to thehydraulic design criteria, and recognition of a fourth proport
34、ioning method.The 1999 edition combined NFPA 16 and NFPA 16A into one comprehensive document.Numerous editorial changes also were instituted.The 2003 edition was reformatted to conform to the Manual of Style for NFPA TechnicalCommittee Documents and was revised to recognize the use of different type
35、s and brands of foamconcentrate.The 2007 edition of the standard was revised to coordinate definitions and requirementsfor fire department connections and underground pipe with those of other documents.The 2011 edition was updated to clarify the criteria for acceptance testing of the concen-tration
36、of foam to specific tolerance ranges.The standard clarified that the orifice indicator tabs or nameplate must be permanentlymarked. The 2011 edition also made the hose stream allowance consistent with NFPA 13,Standard for the Installation of Sprinkler Systems. In addition, the alcohol-resistant foam
37、s did notfollow the Darcy-Weisbach formula because they are non-Newtonian fluids, and a change wasmade to consult the manufacturers regarding friction loss.The 2015 edition of NFPA 16 updates several definitions for foam water system types,including foam-water sprinkler system, foam-water deluge sys
38、tem, foam-water dry pipe system,and foam-water preaction system. The strainer and galvanized piping C-factor requirementshave been revised to correlate with NFPA 13. Multiple changes have been made to the stan-dard from a system acceptance perspective. Language has been added to the acceptancetestin
39、g criteria to confirm that the proportioning system meets the actual calculated systemdischarge demand at the most remote four sprinklers. Finally, the Contactors Material andTest Certificate from NFPA 13 has been added for correlation purposes.161NFPA and National Fire Protection Association are re
