The work of preparing International Standards

21、 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 liaison with ISO, also take p

22、art 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 technical committees is to

23、 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 drawn to the possibility t

ISO 15181-3 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varn

25、ishes. ISO 15181 consists of the following parts, under the general title Paints and varnishes Determination of release rate of biocides 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

26、release rate Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the concentration of ethylenethiourea in the extract Part 4: Determination of pyridine-triphenylborane (PTPB) concentration in the extract and calculation of the release rate Part 5: C

27、alculation of the tolylfluanid and dichlofluanid release rate by determination of the concentration of dimethyltolylsulfamide (DMST) and dimethylphenylsulfamide (DMSA) in the extract EN ISO 15181-3:2007vIntroduction By using standard conditions of temperature, salinity and pH at low biocide concentr

28、ations 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 actual release rate of bioc

29、ides 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 a particular area. The r

30、esults 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 for regulatory purposes.

31、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 measurements made on panels exposed in harbours, all available data indicate that the results obtained using this generic test method signific

32、antly overestimate the release rates 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 of about 10 or more for

33、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 taken into account. Where the

34、 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 environmental inputs be taken int

35、o 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. EN ISO 15181-3:2007blank1Paints and varnishes Determination of release rat

36、e of biocides from antifouling paints Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the concentration of ethylenethiourea in the extract 1 Scope This part of ISO 15181 specifies the apparatus and analytical method for determining the amount of

37、 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 des

38、cribes 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

39、 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 i

40、n 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 gcm2d1to 500 gcm2d1. The quantitative measurement of release rates below this range will require the use of an analytical method with a lower li

44、h the procedure given in ISO 15181-1 is determined by degrading the ethylene-bis(dithiocarbamate) species in the leachate under controlled conditions and determining the concentration of the degradation product, ethylenethiourea (ETU), by high-performance liquid chromatography (HPLC) or by an altern

45、ative analytical method, provided that it demonstrates a limit of quantitation for ETU in artificial seawater of 6 g/l or less. The release rate of the biocide under the specified laboratory conditions is then calculated as zineb. Additional information on zineb and ETU is given in Annex B. 4 Supple
