25、 Switzerland and the United Kingdom. Endorsement notice The text of ISO 15181-5:2008 has been approved by CEN as a EN ISO 15181-5:2008 without any modification. Introduction By using standard conditions of temperature, salinity and pH at low biocide concentrations in the surrounding artificial seawa

26、ter, 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 biocides from antifouling paints on ships hull

27、s into the environment will, however, depend on many factors, such as ship operating schedules, length of service, berthing conditions, paint condition, as well as temperature, salinity, pH, pollutants and biological community in a particular area. The results of this test do not reflect environment

28、al 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. In comparison with copper and organotin releas

29、e 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 significantly overestimate the release rates of biocid

30、es under in-service conditions. Published results demonstrate that the results of this test method are generally higher by a factor of about 10 or more for several commercial antifouling coatings than direct in situ measurements of copper and organotin release rates from in-service ship hulls 1, 2.

31、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 results of this test method are used in the

32、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 into account to allow a more accurate estimate o

33、f 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. 4 DIN EN ISO 15181-5:2008-09EN ISO 15181-5:2008 (E)1 Scope This part of ISO 15181 specifies the apparatus and analytica

34、l method for determining the amount of tolylfluanid and dichlofluanid that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1. Tolylfluanid and dichlofluanid are unstable in the marine environment and degrade to form dimethyltol

35、ylsulfamide (DMST) and dimethylphenylsulfamide (DMSA), respectively. This part of ISO 15181 specifies a method for converting the released species into these degradation products, quantifying their concentration in the treated artificial seawater samples, and gives the final calculation for the rele

36、ase rate of tolylfluanid and dichlofluanid under the specified laboratory conditions. This part of ISO 15181 is designed to allow the concurrent determination of tolylfluanid, dichlofluanid and other biocides that can be released by a given antifouling paint (for example, copper) through the analysi

37、s of separate sub-samples of an artificial seawater extract generated in accordance with ISO 15181-1. When used in conjunction with ISO 15181-1, the practical limits for quantifying release rates by this method are from 1,3 gcm2d1to 500 gcm2d1. The quantitation of release rates lower than this range

38、 will require the use of an analytical method with a lower limit of quantitation for tolylfluanid, dichlofluanid, or both (as appropriate) in artificial seawater than that specified in Clause 3 and in 5.1. 2 Normative references The following referenced documents are indispensable for the applicatio

41、iple The amount of tolylfluanid released from a test cylinder into artificial seawater by the method given in ISO 15181-1 is determined by promoting the degradation of the tolylfluanid in the leachate under controlled conditions and subsequently quantifying the concentration of the degradation produ

42、ct, dimethyltolylsulfamide (DMST), by a high-performance liquid chromatography (HPLC) method or by an alternative analytical method, provided that it has a limit of quantitation for tolylfluanid in artificial seawater of 7 g/l or less. The release rate of the biocide under the specified laboratory c

43、onditions is then calculated as tolylfluanid. The amount of dichlofluanid released from a test cylinder into artificial seawater by the method given in ISO 15181-1 is determined by promoting the controlled degradation of the dichlofluanid in the leachate, and quantifying the concentration of the deg

44、radation product, dimethylphenylsulfamide (DMSA), by a similar HPLC method or by an alternative analytical method, provided that it demonstrates a limit of quantitation for dichlofluanid in artificial seawater of 7 g/l or less. The release rate of the biocide under the specified laboratory condition

45、s is then calculated as dichlofluanid. Additional information on tolylfluanid, dichlofluanid, DMST and DMSA is given in Annex B. 4 Supplementary information The items of supplementary information required to be able to use the general extraction procedure, described in ISO 15181-1, for dichlofluanid

The limit of quantitation shall be

47、determined by the general procedure given in Annex 2 of ASTM D 6442-06 (Determination of the LOQ for Copper in Substitute Ocean Water for the Analytical Method), suitably modified for tolylfluanid, dichlofluanid, or both (as appropriate).
