NFPA 18 Standard on Wetting Agents 2017 Edition This edition of NFPA 18, Standard on Wetting Agents, was prepared by the Technical Committee on Water Additives for Fire Control and Vapor Mitigation. It was

12、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 18 was approved as an American National Standard on December 1, 2016. Origin and Development of NFPA 18 This standard was originally sponsored

13、by the NFPA General Committee on Special Extinguishing Methods and prepared by the NFPA Committee on Wetting Agents. Initiated and tentatively adopted in 1949, it was ofcially adopted in 1951. Extensive revisions, most of which were concerned with the use of wetting agent foam, were adopted in 1955.

14、 Subsequently, in 1959, responsibility for this standard was transferred to the Committee on Foam, and the standard was amended in 1972 and 1979. The 1986 and 1990 editions of the standard were reconrmations of the 1979 edition. The 1995 edition of the document also was a reconrmation. However, some

15、 editorial changes were incorporated in an effort to make the document more user friendly. The 2006 edition underwent extensive revisions, both technical and editorial. Technical changes included clarifying the denition of wetting agents and their use on specic types of res. Specic requirements for

16、wetting agents and the methods for testing were detailed in Chapter 5, and Chapter 6 contained requirements for the supply of wetting agents. Specic packaging requirements were included in Chapter 7, and inspection, testing, and maintenance requirements for systems using wetting agents were detailed

17、 in Chapter 8. Editorial changes included updating the structure of the standard to comply with the Manual of Style for NFPA Technical Committee Documents and strengthening the language into specic requirements. The 2011 edition also underwent extensive technical and editorial revision. Technical ch

18、anges included limits for aquatic toxicity for parity and consistency with other product standards. Editorial changes included updating the structure of the standard to further comply with the Manual of Style for NFPA Technical Committee Documents. The 2017 edition includes both technical and editor

19、ial revisions. Technical changes include clarication that all aspects of the listing for wetting agents must be observed, an explanation on the units of the corrosion rate equation in Chapter 5, and a new section within Chapter 5 was created to provide requirements for alternate viscosity test metho

20、ds for situations where the viscosity is too low to obtain meaningful results. Editorial changes include updating the standard to comply with the Manual of Style for NFPA Technical Committee Documents.WETTING AGENTS 18-2 2017 Edition Technical Committee on Water Additives for Fire Control and Vapor
