Scope:

These requirements cover automatic sprinklers including conventional, spray, sidewall, extended coverage, residential, certain specific application sprinklers and storage sprinklers including early suppression fast response (ESFR) intended for installation on sprinkler systems for fire-protection service. Requirements for the installation and use of sprinklers are included in the National Building Code of Canada, Standards for the Installation of Sprinkler Systems, NFPA 13; Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, NFPA 13D; and Installation of Sprinkler Systems in Low-Rise Residential Occupancies, NFPA 13R; as well as other applicable NFPA Standards. The requirements in this standard are not intended to restrict the application of representative fire and other tests for special sprinklers, as referenced in Standard for the Installation of Sprinkler Systems, NFPA 13, that are intended to provide protection for specific fire hazards.

Project need:

UL proposes an amendment that would reference the use of polymeric sprinklers in NFPA 13R applications in addition to NFPA 13D. The use of these sprinklers in NFPA 13R installations is proposed based the fact that both NFPA 13D and 13R have an objective of preventing flashover in the room of origin and improve the chance for the occupants to escape or be evacuated. Although polymeric sprinklers are not subjected to the heat resistance test due to the lower melting point of the construction material, extensive additional performance tests are required to evaluate these sprinklers for dwelling use.
