1.1 Scope

  1.1.1 These Guidelines specify the test procedures for the type approval of fixed high-expansion foam systems. The procedures consist of the following parts:

  • .1 appendix 1: fire test procedures for evaluating the fire-extinguishing effectiveness of the foam system;

  • .2 appendix 2: component manufacturing test procedures intended to ensure the operability of the system components in the marine environment; and

  • .3 appendix 3: procedures for determining the discharge capacity of the high-expansion foam generators.

  1.1.2 These Guidelines are not intended for testing the performance of high-expansion foam concentrates.

  1.1.3 Appendix 4 to the Guidelines is an optional small scale test intended to verify the fire-extinguishing effectiveness of high-expansion foam when made with hot, smoke-laden inside air. This test is recommended for quality control of foam concentrates, and may also be used to compare the extinguishing performance of foam concentrates made with freshwater to those made with seawater.
