ISO 15181-2:2007规定了根据ISO 15181-1中给出的程序测定从防污漆释放到人工海水中的铜（基）杀生物剂量的仪器和分析方法。 它确定了铜离子浓度，并给出了特定实验室条件下铜释放率的最终计算结果。其设计通常允许通过分析根据ISO 15181中给出的程序生成的人工海水提取物的单独子样品，同时测定给定防污漆可能释放的铜离子和其他杀生物剂- 1，并根据本国际标准其他部分给出的程序进行分析。 与ISO 15181-1结合使用时，该方法定量测量释放率的实际限值为每天每平方厘米1.8微克到每天每平方厘米500微克。低于该范围的释放率的定量测量需要使用具有铜定量下限的分析方法。

ISO 15181-2:2007 specifies the apparatus and analytical method for determining the amount of copper (based) biocide that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1. It determines the copper-ion concentration and gives the final calculation for the release rate of copper under the specified laboratory conditions. It is designed to generally allow the concurrent determination of copper ions and other biocides that might be released by a given antifouling paint through the analysis of separate sub-samples of an artificial seawater extract generated in accordance with the procedure given in ISO 15181-1, and analysed in accordance with the procedures given in other parts of this International Standard. When used in conjunction with ISO 15181-1, the practical limits on the quantitative measurement of release rates by this method are from 1,8 micrograms per square centimetre per day to 500 micrograms per square centimetre per day. The quantitative measurement of release rates below this range will require the use of an analytical method with a lower limit of quantitation for copper.
