NFPA 16 – Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems
۲۰۱۵ Edition
Chapter 1 Administration
۱-۱ Scope.
۱-۱-۱ 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 building and fire codes or standards such as NFPA 30 or NFPA 409.
۱-۱-۲ This standard shall apply only to systems using low- expansion foam.
۱-۲* Purpose. The purpose of this standard is to provide a reasonable degree of protection for life and property from fire through installation requirements for foam-water sprinkler and spray systems based on sound engineering principles, test data, and field experience.
۱-۳ Application.
۱-۳-۱* Because of the dual extinguishing agent discharge characteristic, these systems shall be selectively applicable to combination Class A and Class B hazards.
۱-۳-۲ Foam-water deluge systems are applicable to the protection of two-dimensional flammable liquid hazards. They shall be permitted to be used for any of the purposes or combinations thereof detailed in 1-3-2-1 through 1-3-2-3.
۱-۳-۲-۱ Extinguishment. The primary purpose of such systems is the extinguishment of fire in the protected hazard. For this purpose, foam solution discharge densities shall be provided by system design, use of selected discharge devices, and provi- sion of supplies of water at required pressures to accomplish the system design. Foam discharge rates shall be able to pro- vide required rates of water discharge from the system until shut off during the design period and following depletion of foam concentrate supplies.
