It was issued by the Standards Council on November 11, 2016, with an effective date of December 1, 2016, and supersedes all previous editions. This edition of NFPA 18A was approved as an

13、 American National Standard on December 1, 2016. Origin and Development of NFPA 18A In 1998, the NFPA Standards Council approved the formation of the Technical Committee on Water Additives for Fire Control and Vapor Mitigation. The committee was tasked with having primary responsibility for document

14、s on the manufacture, testing, application, and use of water additives for the control and/or suppression of re and ammable vapor mitigation, including water additives used to prevent or reduce the spread of re and the use of water additives in xed, semi- xed, mobile, and portable re suppression sys

15、tems. The standard they were given was NFPA 18, Wetting Agents. Initially, the committee proposed to combine wetting agents and water additives under one standard. This effort was returned to the committee by Association action in June 2003. As a result, the committee decided to divide this work int

16、o two subject areas and standards, retaining and revising NFPA 18 and creating a new standard addressing water additives, NFPA 18A, the rst edition of which was issued in 2007. Changes in the 2011 edition include a reorganization of Chapters 5 and 6, clarication of test procedures and criteria, and

17、the removal of secondary (U.S.) units throughout much of the text. The 2017 edition has undergone extensive technical and editorial revision. Technical changes include a new chapter to address Class C re test methods to provide the re service with safe limits for re attack on energized electrical eq

18、uipment. Editorial changes include updating the structure of the standard to further comply with the Manual of Style for NFPA Technical Committee Documents.WATER ADDITIVES FOR FIRE CONTROL AND VAPOR MITIGATION 18A-2 2017 Edition Technical Committee on Water Additives for Fire Control and Vapor Mitig
