ISO 8692:2012规定了通过水中或废水中的物质和混合物测定单细胞绿藻生长抑制的方法。本方法适用于易溶于水的物质。 按照ISO 14442和ISO 5667-16的规定，对该方法进行修改后，可以测试难溶性有机和无机材料、挥发性化合物、重金属和废水的抑制效果。 附录中描述了废水的快速藻类生长抑制筛选试验。 附录中描述了从海藻珠中提取藻类的替代试验程序，可直接测量分光光度计池中的藻类生长。

ISO 8692:2012 specifies a method for the determination of the growth inhibition of unicellular green algae by substances and mixtures contained in water or by waste water. This method is applicable for substances that are easily soluble in water. With modifications to this method, as specified in ISO 14442 and ISO 5667-16, the inhibitory effects of poorly soluble organic and inorganic materials, volatile compounds, heavy metals and waste water can be tested. A rapid algal growth inhibition screening test for waste water is described in an annex. An alternative test procedure with algae from algal beads, with direct measurement of algal growth in spectrophotometric cells, is described in an annex.
