The work of preparing

20、International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaiso

21、n with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of tec

22、hnical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is dra

23、wn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15181-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test meth

24、ods for paints and varnishes. This second edition cancels and replaces the first edition (ISO 15181-2:2000), which has been technically revised. ISO 15181 consists of the following parts, under the general title Paints and varnishes Determination of release rate of biocides from antifouling paints:

25、Part 1: General method for extraction of biocides Part 2: Determination of copper-ion concentration in the extract and calculation of the release rate Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the concentration of ethylenethiourea in the e

27、DMSA) in the extract EN ISO 15181-2:2007vIntroduction By using standard conditions of temperature, salinity and pH at low biocide concentrations in the surrounding artificial seawater, a repeatable value of the release rate under the specified laboratory conditions can be determined using the method

28、 given in this part of ISO 15181, which can be used for quality assurance and material selection purposes. The actual release rate of biocides from antifouling paints on ships hulls into the environment will, however, depend on many factors, such as ship operating schedules, length of service, berth

29、ing conditions, paint condition, as well as the temperature, salinity, pH, pollutants and biological community in a particular area. The results of this test do not reflect environmental biocide release rates for antifouling products and are not suitable for direct use in the process of generating e

30、nvironmental-risk assessments, producing environmental-loading estimates or for establishing release rate limits for regulatory purposes. In comparison with copper and organotin release rates obtained either by direct or indirect measurements of the copper release rate from ships hulls and from meas

31、urements made on panels exposed in harbours, all available data indicate that the results obtained using this generic test method significantly overestimate the release rates of biocides under in-service conditions. Published results demonstrate that the results of this test method are generally hig

32、her than direct in situ measurements of copper and organotin release rates from in-service ship hulls by a factor of about 10 or more for several commercial antifouling coatings1, 2. A similar relationship is expected to be found for other biocides. Realistic estimates of the biocide release rate fr

33、om a ships hull under in-service conditions can only be obtained from this test method if this difference is taken into account. Where the results of this test method are used in the process of generating environmental-risk assessments, producing environmental-loading estimates or for regulatory pur

34、poses, it is most strongly recommended that the relationship between laboratory release rates and actual environmental inputs be taken into account to allow a more accurate estimate of the biocide release rate from antifouling coatings under real-life conditions to be obtained. This can be accomplis

35、hed through the application of appropriate correction factors2.

36、O 15181 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 c

37、alculation for the release rate of copper under the specified laboratory conditions. This part of ISO 15181 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 o

38、f 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 rel

39、ease rates by this method are from 1,8 gcm2d1to 500 gcm2d1. 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 in artificial seawater than the limit specified in 5.1. 2 Normative references The fol
