This edition of NFPA 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and Including Four Stories in Height, was prepared by the Technical Committee on Residential Sprinkler Systems and released by the Technical Correlating Committee on Automatic Sprinkler Systems. It was issued by the Standards Council on May 26, 2009, with an effective date of June 15, 2009, and supersedes all previous editions.
This edition of NFPA 13R was approved as an American National Standard on June 15, 2009.
Origin and Development of NFPA 13R
The first edition of NFPA 13R, which was published in 1989, represented a milestone in the development of sprinkler installation design standards. The first edition resulted in a standard for the protection of low-rise, residential facilities.
This standard is intended to provide a higher degree of life safety and property protection to the inhabitants of low-rise, multifamily dwellings. Promulgated as a document that provides for increased levels of protection to building occupants, the document also considers the economic aspects of a sprinklered facility as compared to an unsprinklered facility.
As the number of states and cities that implement sprinkler ordinances continues to grow, and as the threshold levels for sprinkler requirements in residential occupancies in the building codes extend to certain low-rise structures, it is believed that systems for certain residential occupancies can be efficiently and effectively installed in accordance with this standard.
The 1994 edition provided expanded information on nonmetallic pipe materials, minor changes to clarify the established design criteria, and a new recommendation on underground pipe materials.
The 1996 edition included several changes that paralleled amendments in the 1996 edition of NFPA 13, Standard for the Installation of Sprinkler Systems. Other changes included a number of clarifications concerning the selection of sprinklers as well as the proper use of sprinklers.
The 1999 edition clarified criteria for nonmetallic pipe and fittings and established a minimum operating pressure for sprinklers. Guidance on providing freeze protection using insulation in attics and antifreeze systems was provided, as was information on the application of solvent cement for nonmetallic piping. Exceptions for omitting sprinkler coverage in closets on balconies and underneath garage doors were added.
The 2002 edition incorporated revisions to update the standard to comply with the 2000 edition of the Manual of Style for NFFA Technical Committee Documents. These revisions included editorially rewording any exceptions as requirements. The 2002 edition also included changes that further clarified the scope of the standard, established a minimum design discharge density, and added protection requirements specifically for garages. The section addressing spaces where sprinklers are permitted to be omitted was changed so that the area of full-height tub/shower enclosures would be included in the area determination for bathrooms, sprinklers would be provided in concealed spaces with fuel-fired equipment, and the omission of sprinklers in elevator machine rooms would not be dependent on the room's location.
The 2007 edition included spacing and obstruction rules addressing sloped ceilings, ceiling pockets, ceiling fans, and kitchen cabinets. For the 2007 edition, the requirements for utilizing quick-response sprinklers within NFPA 13R regulations were clarified, and new requirements addressing architectural features within dwelling units were added. Additionally, the requirements covering closets, including obstructions within closets and protection of mechanical closets, were clarified. Finally, new NFPA 13 requirements were added that are applicable to NFPA 13R to ensure proper administration of those requirements where relevant.
The 2010 edition has been reorganized, dividing out material on installation, discharge, plans and calculation, water supplies, acceptance testing, and care and maintenance into separate chapters. Clarification has been provided in the Annex A material of Chapter 1 for assistance in determining when NFPA 13R is applicable and establishing that the building code defines the structure and NFPA 13R is used after such determination has been made. Further clarification has also been added stating that sprinklers are not required on balconies or balcony closets.
