前言
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 对已成立技术委员会的主题感兴趣的每个成员机构都有权在委员会中派代表参加. 与标准化组织联络的政府和非政府国际组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

国际标准是根据第 6 部分给出的规则起草的。 2 ISO/IEC 指令的.

技术委员会的主要任务是制定国际标准. 技术委员会通过的国际标准草案将分发给成员机构进行投票. 作为国际标准的出版至少需要获得批准 75% 成员机构数量.

介绍
By using standard conditions for temperature, salinity and pH at low fungicide concentrations in ambient artificial seawater, reproducible values for release rates under specified laboratory conditions can be determined using the method given in this part of ISO 15181, which can be used for quality assurance and material selection purposes. 然而, the actual rate of release of fungicides from hull antifouling paints into the environment will depend on many factors, such as vessel operating schedules, years of service, berthing conditions, paint condition, as well as temperature, salinity, pH, pollutants and biota in a particular area.

The results of this test do not reflect the environmental fungicide release rate of antifouling products and are not suitable for direct use in the process of generating environmental risk assessments, generating environmental load estimates, or establishing release rate limits for regulatory purposes. When compared with copper and organotin release rates obtained by direct or indirect measurements of hull copper release rates and measurements on panels exposed in ports, all available data indicate that the results obtained using this general test method substantially overestimate the release rate of fungicides under service conditions. Published results show that for several commercial antifouling coatings, the results of this test method are generally about 10 times or more higher than direct in situ measurements of in-service hull copper and organotin release rates [1,2]. Similar relationships are expected to be found for other fungicides. A realistic estimate of the rate of hull fungicide release under service conditions can only be obtained from this test method if this difference is taken into account.

If the results of this testing method are used to generate environmental risk assessments, to produce environmental load estimates, or for regulatory purposes, it is highly recommended to consider the relationship between laboratory release rates and actual environmental inputs in order to more accurately estimate the fungicides release rates of antifouling coatings under real conditions. This can be achieved by applying appropriate correction coefficients [2].

1 范围
ISO的这一部分 15181 specifies the apparatus and analytical methods for determining the bactericidal dose of copper (base) released from antifouling paints into artificial seawater according to the procedures given in ISO 15181-1.

It determines the copper ion concentration and gives a final calculation of the copper release rate under specified laboratory conditions. ISO的这一部分 15181 aims to simultaneously determine the possible release of copper ions and other biocides from a given antifouling paint by analysing separate subsamples of artificial seawater extracts generated according to the procedures specified in ISO 15181-1 and analysed in accordance with the procedures given elsewhere in this standard.

When used in combination with ISO 15181-1, the practical limit for the quantitative measurement of release rate is 1.8μg·cm — 2·d — 1 到 500 μg·cm — 2·d — 1. Quantitative measurement of release rates below this range would require the use of an analytical method with limits of quantitation for copper in artificial seawater below the limits specified in 5.1.
