本国际标准规定了一种方法，用于测定受污染沉积物在接触6天后对介形类甲壳动物异塞浦路斯的致死和亚致死影响。 该方法不仅适用于淡水沉积物，还适用于添加（未污染）水后的固体废物和土壤。 该方法也适用于加入参考沉积物中的化学品或制剂。 本国际标准不适用于河口或海洋环境沉积物的测试。

This International Standard specifies a method for the determination of lethal as well as sublethal effects of contaminated sediments on the ostracod crustacean Heterocypris incongruens after 6 d exposure. The method is applicable not only to fresh water sediments, but also by extension to solid wastes and soils after addition of (uncontaminated) water. The method can also be applied to chemicals or preparations which are spiked into a reference sediment. This International Standard is not applicable to the testing of sediments from the estuarine or marine environment.
