18、tice for Fire Flow Testing and Marking of Hydrants 2013 Edition This edition of NFPA 291, Recommended Practice for Fire Flow Testing and Marking of Hydrants, was prepared by the Technical Committee on Private Water Supply Piping Systems and re- leased by the Technical Correlating Committee on Automa

19、tic Sprinkler Systems. It was issued by the Standards Council on May 29, 2012, with an effective date of June 18, 2012, and supersedes all previous editions. This edition of NFPA 291 was approved as an American National Standard on June 18, 2012. Origin and Development of NFPA 291 The NFPA Committee

20、 on Public Water Supplies for Private Fire Protection presented the idea of indicating the relative available fire service water supply from hydrants in its 1934 report. The Committee felt then and feels now that such an indication is of substantial value to water and fire departments. The following

21、 recommendations were initially adopted in 1935. The Committee agreed that tests of individual hydrants did not give as complete and satisfactory results as group testing but expressed the opinion that tests of individual hydrants did have sufficient value to make the following recommendations worth

22、y of adoption. This was reconfirmed with minor editorial changes in 1974. The 1977 edition was completely rewritten and a chapter on the flow testing of hydrants was added. The 1982 edition was reconfirmed by the Committee. The 1988 edition of the document noted several changes that clarified and re

23、inforced certain recommendations. Specific guid- ance was added on the correct method of utilizing a pitot tube to gain accurate test results. The 1995 edition incorporated several changes in an attempt to make the document more user-friendly. Changes were also incorporated with regard to the layout

24、 of hydrant and water flow tests. The 2002 edition clarified the recommendations for flow tests and was restructured to comply with the Manual of Style for NFPA Technical Committee Documents. The 2007 edition represented a reconfirmation of the 2002 edition, as there were no technical changes. The 2

25、010 edition clarified the responsibility for marking of hydrants. The 2013 edition of NFPA 291 adds language recommending frequencies for flushing and flow testing of public hydrants in Section 4.13. 2911 NFPA and National Fire Protection Association are registered trademarks of the National Fire Pr
