EN ISO 15181-4:2008 (E) DIN EN ISO 15181-4:2009-02 3Introduction By using standard conditions of temperature, salinity and pH at low biocide concentrations in the surrounding artificial seawater, a repeatable

27、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 actual release rate of biocides from antifouling paints on ships hulls into the environ

28、ment 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 a particular area. The results of this test do not reflect environmental biocide rel

29、ease 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 for regulatory purposes. In comparison with copper and organotin release rates obtain

30、ed 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 generic test method significantly overestimate the release rate of biocides under in-s

31、ervice 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 of about 10 or more for several commercial antifouling coatings1, 2. A similar rela

32、tionship 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 taken into account. Where the results of this test method are used in the process of gen

33、erating 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 environmental inputs be taken into account to allow a more accurate estimate of the biocide

34、release rate from antifouling coatings under real-life conditions to be obtained. This can be accomplished through the application of appropriate correction factors2. EN ISO 15181-4:2008 (E) DIN EN ISO 15181-4:2009-02 41 Scope This part of ISO 15181 specifies the apparatus and analytical method for

35、determining the amount of pyridine-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 r

36、elease rate of PTPB under the specified 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 seawa

37、ter 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 1,8 gcm2d1to 500 gcm2d1. The quantitative measurement of release rates below this rang

38、e will require the concentration 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 i

41、 EN ISO 15181-4:2009-02 53 Principle The quantity of PTPB biocide 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

42、 an alternative analytical method provided that it demonstrates 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 addition

43、al sample concentration step described in the last paragraph 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 T

44、akahashi, et al.3. 4 Supplementary information The items of supplementary information required to be able to use the general extraction procedure, described in ISO 15181-1, for PTPB are given in Annex A. 5 Apparatus 5.1 High-performance liquid chromatograph (HPLC), or other equivalent instrument, wh

45、ich has a limit of quantitation for PTPB in artificial seawater of 10 g/l or less. The limit of quantitation shall be determined by the procedure given in Annex 2 (Determination of the LOQ for Copper in Substitute Ocean Water for the Analytical Method) of ASTM D 6442-06, suitably modified for PTPB.
