29、5181-6:2014-09 EN ISO 15181-6:2014 (E) 3 IntroductionBy 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
30、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 depends, however, on many factors, such as ship operating schedules, length of service, berthing c
31、onditions, paint condition, as well as temperature, salinity, pH, pollutants, and biological community.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,
32、 producing environmental loading estimates or for establishing release rate limits for regulatory purposes. In comparison with copper and organotin release rate measurements obtained either by direct or indirect measurements of the copper release rate from ships hulls and from measurements made on p
33、anels exposed in harbours, all available data indicate that the results of this generic test method significantly overestimate the release rate of biocide under in-service conditions. Published results demonstrate that the results of this test method are generally higher than direct in-situ measurem
34、ents of copper and organotin release rate from the hulls of harboured ships by a factor of about 10 or more for several commercial antifouling coatings.12A similar relationship is expected to be found for other biocides. Realistic estimates of the biocide release from a ships hull under in-service c
35、onditions 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 purposes, it is most strongly recommen
36、ded that the relationship between laboratory release rates and actual environment 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 approp
37、riate correction factors.2DIN EN ISO 15181-6:2014-09 EN ISO 15181-6:2014 (E) 4 1 ScopeThis part of ISO 15181 specifies a method for determining the amount of tralopyril that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1.Tra
38、lopyril is unstable in water and degrades hydrolytically to form 3-bromo-5-(4-chlorophenyl)-4-cyano-1H-pyrrole-2-carboxylic acid (BCCPCA). This part of ISO 15181 specifies a method for accelerating the conversion of the released tralopyril into this degradation product by heat treatment and quantify
39、ing the concentration of the BCCPCA degradation product in the artificial seawater extract, and gives the final calculation for the release rate of tralopyril under the specified laboratory conditions.This part of ISO 15181 is designed to allow the concurrent determination of tralopyril and other bi
40、ocides 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 accordance with ISO 15181-1.When used in conjunction with ISO 15181-1, the practical limits for quantifying release rates by this
41、method are from 0,36 g cm2d1to 270 g cm2d1. The quantitation of release rates lower than this range requires the use of an analytical method with a limit of quantitation for tralopyril in artificial seawater of less than 2 g/l.2 Normative referencesThe following referenced documents are indispensabl

44、sed into artificial seawater by the method given in ISO 15181-1 is determined by accelerating the hydrolytic degradation of the tralopyril in the leachate by heat treatment under controlled conditions and subsequently quantifying the concentration of the degradation product, 3-bromo-5-(4-chloropheny
45、l)-4-cyano-1H-pyrrole-2-carboxylic acid (BCCPCA) by high-performance liquid chromatography (HPLC) or by an alternative method, provided that it demonstrates a limit of quantitation for tralopyril in artificial seawater of 2 g/l or less. The release rate of the biocide under the specified laboratory
46、conditions is then calculated as tralopyril.NOTE Additional information on tralopyril and BCCPCA is given in Annex B.DIN EN ISO 15181-6:2014-09 EN ISO 15181-6:2014 (E) 5 4 Supplementary informationThe items of supplementary information required to be able to use the general extraction procedure, des
