This International Standard specifies a method of measurement of the foaming power of a surface active agent. The method is applicable to all surface active agents. Measurement of the foaming power of solutions of readily hydrolysable agents, however, does not give reliable results, as the hydrolysis products collect in the films of liquid and affect the persistence of the foam. Foaming power is also very sensitive so small variations in composition. Consequently, the results obtained on formulated products should be interpreted with caution. The method is not applicable for measurement of the foaming power of very dilute solutions of surface active agents, such as river waters containing surface active agents.
