标准范围

ISO 15181-3:2007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锌含量的仪器和分析方法。锌以离子乙烯双（二硫代氨基甲酸酯）的形式从防污涂料中释放，在海洋环境中不稳定。ISO 15181的这一部分描述了将释放的物种转化为稳定降解产物乙烯基硫脲并测定其在处理过的人工海水样品中浓度的方法，并给出了在规定实验室条件下锌释放率的最终计算。ISO 15181的这一部分旨在通过分析单独的亚组分，同时测定给定防污漆（例如铜）可能释放的锌和其他杀生物剂-根据ISO 15181-1中给出的程序生成的人工海水提取物样品。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每天每平方厘米2.9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将需要使用具有乙撑硫脲定量下限的分析方法。

ISO 15181-3:2007 specifies the apparatus and analytical method for determining the amount of zineb that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1.Zineb is released from antifouling paints in the form of ionic ethylene-bis(dithiocarbamate) which is unstable in the marine environment. This part of ISO 15181 describes a method for converting the released species into a stable degradation product, ethylenethiourea, and determining its concentration in the treated artificial seawater samples, and gives the final calculation for the release rate of zineb under the specified laboratory conditions.This part of ISO 15181 is designed to generally allow the concurrent determination of zineb and other biocides that can be released by a given antifouling paint (for example, copper) through the analysis of separate sub-samples of an artificial seawater extract generated in accordance with the procedure given in ISO 15181-1.When used in conjunction with ISO 15181-1, the practical limits on the quantitative measurement of release rates by this method are from 2,9 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 ethylenethiourea.
