NFPA 13D Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes 2016 Edition This edition of NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, was prepare
31、d by the Technical Committee on Residential Sprinkler Systems and released by the Correlating Committee on Automatic Sprinkler Systems. It was issued by the Standards Council on May 26, 2015, with an effective date of June 15, 2015, and supersedes all previous editions. This edition of NFPA 13D was
32、approved as an American National Standard on June 15, 2015. Origin and Development of NFPA 13D Recognizing the need to reduce the annual life loss from re in residential occupancies (about 50 percent of total loss of life by re), the Committee on Automatic Sprinklers appointed a subcommittee in May
33、1973 to prepare the Standard on the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Mobile Homes. The subcommittee was composed of members of the Committee on Automatic Sprinklers and other technically competent experts. The standard was submitted and adopted at the NFPA Annua
34、l Meeting in Chicago, Illinois, on May 1216, 1975. The 1980 edition was a complete rewrite of the 1975 edition, including SI units where appropriate. The 1980 edition incorporated the results of the residential sprinkler test program administered by the National Fire Protection Association and funde
35、d by a research grant from the United States Fire Administration. Factory Mutual Research Corporation and the Los Angeles City Fire Department conducted the dwelling tests. Factory Mutual Research Corporation, McNeary Insurance Consulting Services, and the Charlotte, North Carolina, Fire Department
36、conducted the mobile home tests. After gaining practical experience using the 1980 edition, modications to the standard, including removal of design parameters for dry pipe systems, were made in the 1984 edition. The 1989 and 1991 editions established criteria for the use of antifreeze systems as we
37、ll as some of the installation criteria associated with specially listed piping materials. The 1994 edition provided expanded information on nonmetallic pipe and introduced a new design option that reduced water storage requirements for limited area dwellings. The 1996 edition of the standard includ
38、ed expanded information on the use and placement of residential sprinklers near heat sources. For the rst time since 1941, the use of in. (12.7 mm) piping material was permitted again for sprinkler systems under specic conditions. A number of appendix gures were also added to address methods for pro
39、tecting pipe from freezing in unheated attics. The 1999 edition revised criteria for certain types of multipurpose piping systems and added requirements to mitigate the effect of water softeners and lters on system performance. Information on the application of solvent cement for nonmetallic piping
40、systems was provided, and the exception for omitting sprinkler coverage in attics and crawl spaces was modied. The 2002 edition incorporated revisions to update the standard to comply with the 2000 edition of the Manual of Style for NFPA Technical Committee Documents. These revisions included editor
41、ially rewording any exceptions as requirements. The 2002 edition also included changes that established a minimum design discharge density. The requirements for multipurpose systems were changed to require a bypass valve for installations with water softeners or water ltration equipment installedINS
42、TALLATION OF SPRINKLER SYSTEMS IN ONE- AND TWO-FAMILY DWELLINGS AND MANUFACTURED HOMES 13D-2 2016 Edition and to update the requirements for network systems. The chapter specically addressing limited area dwelling systems was no longer included in the standard. The 2007 edition included new spacing
43、and obstruction rules addressing sloped ceilings, ceiling pockets, ceiling fans, and kitchen cabinets. Also new to this edition were installation, design, and acceptance requirements for pumps. The acceptability of insulation as a method of freeze protection and the acceptability of wells as a water
44、 source were claried for this edition. New requirements for listed dry pipe/preaction residential sprinkler systems, as well as claried requirements for multipurpose combined and networked sprinkler systems, were incorporated. Finally, specic obstruction rules were added for residential sprinklers.
45、In the 2010 edition new requirements were added for a prescriptive pipe sizing method as an alternative to the hydraulic calculation method. The standard added the term townhouses to the denition of dwelling in order to clarify that townhouses that meet the denition of dwelling can be protected by a
46、n NFPA 13D system. Finally, annex material was added to provide clear guidance for the owner on how to properly inspect, test, and maintain the system. The 2013 edition of NFPA 13D included a restructuring to make the document easier to use. Four new chapters were added, breaking out freeze protecti
47、on, acceptance testing, maintenance, and discharge criteria into their own chapters. This edition has also seen modication to the denitions of multipurpose and stand-alone systems, along with a new denition for passive purge systems. New language addressing the number of heads to be calculated for c
48、ertain sloped and beamed ceiling congurations was added based on a Fire Protection Research Foundation report. The antifreeze requirements were updated through a series of TIAs that were developed based on FPRF testing. Several signicant revisions have been made during the development of the 2016 ed
49、ition. A new gure addresses positioning of sprinklers to avoid obstructions where there are sloped ceilings. Clarication has been added that once a sprinkler is removed from a tting or welded outlet it should not be reinstalled if torque was applied to the sprinkler itself. A new sketch shows an insulation practice using tenting in an attic or concealed space. One of the largest changes to the 2016 edition of NFPA 13D is the review of all metric conversions. Historically the document has used an “exact“ conversion process, but in the 2016 edi
