This International Standard specifies a method for the determination of the inhibition of growth of the
unicellular marine algae Skeletonema costatum and Phaeodactylum tricornutum by substances and mixtures
contained in sea water.
The method can be used for testing substances that are readily soluble in water and are not significantly
degraded or eliminated in any other way from the test medium.
NOTE With modifications, as described in ISO 14442 and ISO 5667-16, the inhibitory effects of poorly soluble
organic and inorganic materials, volatile compounds, metal compounds, effluents, marine water samples and elutriates of
sediments can be tested.
