This International Standard specifies a method for the determination of the chronic toxicity to Ceriodaphnia dubia (Cladocera, Crustacea), based on reproduction inhibition after (7 ± 1) d. The method is applicable to: chemical substances which are soluble or which can be maintained as stable suspensions or dispersions under the conditions of the test; industrial or sewage effluents, if appropriate after decantation, filtration or centrifugation; fresh waters; aqueous extracts. This International Standard is not applicable to the testing of aquatic samples from the estuarine or marine environment.
