标准摘要
[中文适用范围]： ISO 15181 的这一部分规定了根据 ISO 15181-1 中给出的程序测定防污涂料释放到人造海水中的铜（基）杀菌剂含量的仪器和分析方法。 它测定铜离子浓度并给出指定实验室条件下铜释放率的最终计算结果。 ISO 15181 的这一部分旨在通常允许通过分析根据 ISO 给出的程序生成的人造海水提取物的单独子样品，同时测定给定防污涂料可能释放的铜离子和其他杀菌剂。 15181-1，并按照本国际标准其他部分给出的程序进行分析。 当与 ISO 15181-1 结合使用时，通过该方法定量测量释放率的实际限值为 1.8 μg·cm–2·d–1 至 500 μg·cm–2·d–1。 低于此范围的释放率的定量测量将需要使用人工海水中铜的定量限低于 5.1 中规定的限值的分析方法。 [外文原描述]： 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.
