本文件规定了在以贻贝为试验生物的流通系统中筛选防污涂料的实验室试验方法。它将与ISO 21716-1一起使用，后者规定了一般要求。试验的目的是确定在试验条件下，与惰性无毒控制面板上的贻贝沉降相比，涂漆试验面板上的贻贝沉降是否存在差异。附录A中给出了统计分析示例，以确定贻贝沉降差异是否具有统计意义。

This document specifies a laboratory test method for screening anti-fouling paints in a flow-through system using mussels as the test organism. It is intended to be used in conjunction with ISO 21716-1, which specifies the general requirements. The purpose of the test is to determine if there is a difference in mussel settlement on painted test panels compared with mussel settlement on inert non-toxic control panels under the conditions of the test. Examples of statistical analysis to determine if the difference in mussel settlement is statistically significant are given in Annex A.
