Appendix 3 – Foam Generator Capacity Tests

  1 Representative foam generators should be tested to demonstrate their nominal foam production rate over the manufacturer's specified range of inlet pressures. The results of the testing should be reflected in the manufacturer's design and installation manual.

  2 The generator should be connected to a suitable water and foam concentrate supply through a pressure regulating device. The generator should then be operated throughout a pressure range of 50% to 150% of the nominal operating pressure in 1 bar increments.

  3 The generator should be used to fill a fixed volume container at each tested pressure. The time to fill the container should be recorded and used to calculate the generator output in m3/min.

  4 The nominal foam production rate of the generator should be recorded at all test pressures.

  5 The nominal foam production rate of the generator should be greater than or equal to the manufacturer's specified rating.
