25、 for Fire Control and Vapor Mitigation2011 EditionThis edition of NFPA 18A, StandardonWaterAdditivesforFireControlandVaporMitigation, wasprepared by the Technical Committee on Water Additives for Fire Control and Vapor Mitiga-tion. It was issued by the Standards Council on December 14, 2010, with an
26、 effective date ofJanuary 3, 2011, and supersedes all previous editions.This edition of NFPA 18A was approved as an American National Standard on January 3, 2011.Origin and Development of NFPA 18AIn 1998, the NFPA Standards Council approved the formation of the Technical Committee onWater Additives
27、for Fire Control and Vapor Mitigation. The committee was tasked with havingprimary responsibility for documents on the manufacture, testing, application, and use of wateradditives for the control and/or suppression of fire and flammable vapor mitigation, includingwater additives used to prevent or r
28、educe the spread of fire and the use of water additives in fixed,semi-fixed, mobile, and portable fire suppression systems. The standard they were given wasNFPA 18, WettingAgents.Initially, the committee proposed to combine wetting agents and water additives underone standard. This effort was return
29、ed to the committee by Association action in June 2003. Asa result, the committee decided to divide this work into two subject areas and standards,retaining and revising NFPA 18 and creating a new standard addressing water additives,NFPA 18A, the first edition of which was issued in 2007.Changes in
30、the 2011 edition include a reorganization of Chapters 5 and 6, clarification oftest procedures and criteria, and the removal of secondary (U.S.) units throughout much ofthe text.18A1NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Q
