State-of-the-art home sprinkler systems require the improved NFPA 13D.
Install home fire sprinkler systems with NFPA 13D and save lives!
In home fires, the risk of dying decreases by about 80% when sprinklers are present. The 2010 NFPA 13D: Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes presents updated rules for every aspect of sprinkler design, water supplies, equipment, and placement.
Major changes in this edition:
- To encourage widespread use of sprinkler systems, a new eight-step prescriptive pipe sizing method is presented as an alternative to the hydraulic calculation method.
- NFPA 13D's scope has been expanded to include inspection, testing, and maintenance.
- Text clarifies that "townhouses" can be protected by an NFPA 13D system.
- A new annex provides maintenance and testing information needed by homeowners.
Give people the fire protection they deserve with NFPA 13D.
This edition of NFPA 13D, Standard for Installation of Sprinkler Systems in One and Two-Family Dwellings and Manufactured Homes, was prepared by the Technical Committee on Residential Sprinkler Systems and released by the Technical Correlating Committee on Automatic Sprinkler Systems, and acted on by NFPA at its June Association Technical Meeting held June 8-11, 2009, in Chicago, IL. It was issued by the Standards Council on August 6, 2009, with an effective date of August 26, 2009, and supersedes all previous editions.
This edition of NFPA 13D was approved as an American National Standard on August 26, 2009.
Origin and Development of NFPA 13D
Recognizing the need to reduce the annual life loss from fire in residential occupancies (about 50 percent of total loss of life by fire), the Committee on Automatic Sprinklers appointed a subcommittee in May 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 Annual Meeting in Chicago, Illinois, on May 12-16, 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 funded 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 conducted the mobile home tests.
After gaining practical experience using the 1980 edition, modifications 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 well 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 included expanded information on the use and placement of residential sprinklers near heat sources. For the first time since 1941, the use of ½ in. (12.7 mm) piping material was permitted again for sprinkler systems under specific conditions. A number of appendix figures were also added to address methods for protecting 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 filters on system performance. Information on the application of solvent cement for nonmetallic piping systems was provided, and the exception for omitting sprinkler coverage in attics and crawl spaces was modified.
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 editorially 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 filtration equipment installed and to update the requirements for network systems. The chapter specifically addressing limited area dwelling systems was no longer included in the standard.
The 2007 edition included new spacing 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 source were clarified for this edition. New requirements for listed dry pipe/preaction residential sprinkler systems, as well as clarified requirements for multipurpose combined and networked sprinkler systems, were incorporated. Finally, specific obstruction rules were added for residential sprinklers.
In the 2010 edition new requirements have been added for a prescriptive pipe sizing method as an alternative to the hydraulic calculation method. The standard added the term townhouses to the definition of dwelling in order to clarify that townhouses that meet the definition of dwelling can be protected by an NFPA 13D system. Finally, there is annex material added to provide clear guidance for the owner on how to properly inspect, test, and maintain the system.
