NFPA 16 Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems
NFPA 16 雨淋泡沫－自动喷水和泡沫－水喷雾灭火系统

1.1 Scope.

1.1.1 This standard contains minimum requirements for the design, installation, and maintenance of foam-water sprinkler and spray systems. These systems shall be designed with the required density for either foam or water application as the controlling factor, depending on the design purpose of the system. It is not the intent of this standard to specify where foam-water sprinkler and spray protection is required. The determination of where foam-water sprinkler and spray systems are required shall be made in accordance with such applicable standards as NFPA 30, Flammable and Combustible Liquids Code, and NFPA 409, Standard on Aircraft Hangars.

1.1.2* This standard shall apply only to systems using low-expansion foam.

Use best practices to install foam-water fire protection systems with the 2011 NFPA 16!

NFPA 16 Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems outlines requirements for the design, installation, and maintenance of systems for reliable fire protection. Consult the 2011 Standard for the latest on components; water supplies; design and installation; acceptance tests; and inspection, testing, and maintenance. Systems are to be designed with the required density for either foam or water application as the controlling factor, depending on the design purpose.

Changes in this edition address

·   Use of recycled foam solution for pre-priming the systems

·   Determining friction loss in hydraulic calculations

·   Identifying specific tolerance ranges for foam concentration

The 2011 NFPA 16 also clarifies appropriate system design areas, and adds hose stream demand and duration to the calculations. (Softbound, 32 pp., 2011)
