18、e International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committ

19、ee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechn

20、ical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member

21、bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn 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

22、any or all such patent rights. ISO 15181-4 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. ISO 15181 consists of the following parts, under the general title Paints and varnishes Determination of release rate of b

23、iocides from antifouling paints: 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 concentra

24、tion of ethylenethiourea in the extract Part 4: Determination of pyridine-triphenylborane (PTPB) concentration in the extract and calculation of the release rate Part 5: Calculation of the tolylfluanid and dichlofluanid release rate by determination of the concentration of dimethyltolylsulfamide (DM

25、ST) and dimethylphenylsulfamide (DMSA) in the extract The following part is under preparation: Part 6: Determination of tralopyril release rate by quantification of its degradation product in the extract BS EN ISO 15181-4:2008vIntroduction By using standard conditions of temperature, salinity and pH

26、 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 given in this part of ISO 15181, which can be used for quality assurance and material selection purposes. The act

27、ual 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, berthing conditions, paint condition, as well as the temperature, salinity, pH, pollutants and biological community in

28、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 environmental-risk assessments, producing environmental-loading estimates or for establishing release rate limits f

29、or regulatory purposes. In comparison with copper and organotin release rates obtained either by direct or indirect measurements of the copper and organotin release rate from ships hulls and from measurements made on panels exposed in harbours, all available data indicate that the results of this ge

30、neric test method significantly overestimate the release rate of biocides under in-service conditions. Published results demonstrate that the results of this test method are generally higher than direct in situ measurements of copper and organotin release rates from in-service ship hulls by a factor

31、 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 from a ships hull under in-service conditions can only be obtained from this test method if this difference is take

32、n 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 purposes, it is most strongly recommended that the relationship between laboratory release rates and actual environm

33、ental 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 accomplished through the application of appropriate correction factors2. BS EN ISO 15181-4:2008blank1Paints and varnishes

34、Determination of release rate of biocides from antifouling paints Part 4: Determination of pyridine-triphenylborane (PTPB) concentration in the extract and calculation of the release rate 1 Scope This part of ISO 15181 specifies the apparatus and analytical method for determining the amount of pyrid

35、ine-triphenylborane (PTPB) that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1. It determines the PTPB concentration in the artificial seawater extract and gives the final calculation for the release rate of PTPB under the s

36、pecified laboratory conditions. This part of ISO 15181 is designed to allow the concurrent determination of PTPB and other biocides that can be released by a given antifouling paint (for example zineb) through the analysis of separate sub-samples of an artificial seawater extract generated in accord

37、ance 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 1,8 gcm2d1to 500 gcm2d1. The quantitative measurement of release rates below this range will require the concentratio

38、n step described in the last paragraph in 8.2 or the use of an analytical method with a limit of quantitation for PTPB in artificial seawater which is lower than the limit specified in Clause 3 and in 5.1. 2 Normative references The following referenced documents are indispensable for the applicatio

41、iocide released into artificial seawater by the method given in ISO 15181-1 is determined by the use of a high-performance liquid chromatograph (HPLC) with UV detection at 220 nm after pre-concentration by solid-phase extraction (SPE), or by an alternative analytical method provided that it demonstr

42、ates a limit of quantitation for PTPB in artificial seawater of 10 g/l or less. The release rate of the biocide under the specified laboratory conditions is then calculated as PTPB. The use of the HPLC method in conjunction with the additional sample concentration step described in the last paragrap

43、h in 8.2 can allow a limit of quantitation for PTPB in artificial seawater of 0,5 g/l to be achieved. NOTE Additional information on PTPB is given in Annex B. Additional background information on the analytical method has been published by Takahashi, et al.3. 4 Supplementary information The items of
