Underwriters for Sprinkler Equipments, Automatic and Open Systems, the. Originally titled Rules and Regulations of the National Board of Fire. NFPA 13 represents the first standard published under the auspices of the NFPA Commit- tee on Automatic Sprinklers. 2 and other subsections such as 6.3.7.8 and 8.4.8 allow the use of materials and devices not specifically designated by this standard, provided such use is within parameters established by a listing organization. Purpose Since its inception, this document has been developed on the basis of standardized materials, devices, and design practices. Where these systems are installed, they are also designed for protection of a fire from a single ignition source. This standard also provides guidance for the installation of systems for exterior protection and specific hazards. This standard is written with the assumption that the sprinkler system shall be designed to protect against a single fire originating within the building. This standard shall not provide requirements for the design or installation of water mist fire protection systems, which are not considered fire sprinkler systems and are addressed by NFPA 750. This standard shall provide the minimum requirements for the design and installation of automatic fire sprinkler systems and exposure protection sprinkler systems covered within this standard. Building owners and their designated representatives are advised to carefully evaluate proposed selections for appropriateness and preference.
This standard provides a range of sprinkler system approaches, design development alternatives, and component options that are all acceptable.
