24、 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 given in this part of ISO 15181, which can be used for qualit

25、y assurance and material selection purposes. The actual 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, s

26、alinity, pH, pollutants and biological community in 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

27、 estimates or for establishing release rate limits for regulatory purposes. 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 dat

28、a indicate that the results obtained using this generic test method significantly 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 r

29、elease rates from in-service ship hulls by a factor 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 obtain

30、ed 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 recommended that the relationship b

31、etween laboratory release rates and actual environmental 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

32、. EN ISO 15181-1:2007 (E) 4 1 Scope This part of ISO 15181 specifies a general method for extracting biocides from antifouling paint films into artificial seawater under specified laboratory conditions. It is used in conjunction with the other parts of ISO 15181 to determine the amounts of specific

33、biocides in the extract, for example copper and/or certain organic biocides, and to enable the release rate of those biocides from the paint film under the specified laboratory conditions to be calculated. 2 Normative references The following referenced documents are indispensable for the applicatio

39、e Preparation of Substitute Ocean Water EN ISO 15181-1:2007 (E) 5 3 Principle Test cylinders painted with antifouling paint are immersed, together with reference cylinders, in flowing artificial seawater in a holding tank. At specified time intervals, the cylinders are removed and exposed for a defi

40、ned period in individual release rate measuring containers containing the same artificial seawater before being replaced in the holding tank. The concentration of the biocide released into the water of the individual release rate measuring containers is then determined. This operation is repeated at

41、 defined time intervals and hence the release rate of the biocide under the specified laboratory conditions can be calculated. 4 Required supplementary information For each application, the items of supplementary information listed in Annex A shall be supplied as appropriate to enable the test metho

42、d given in this part of ISO 15181 to be carried out. 5 Apparatus NOTE Some biocides have a strong tendency to adsorb onto certain glass or plastic substrates. 5.1 Test cylinder, made of an inert material see Annex A, item A.2 a), having a diameter of (64 5) mm and length of (178 15) mm, and closed a

43、t both ends so that it is watertight. 5.2 Rotating device, capable of rotating a test cylinder (5.1) in the centre of the release rate measuring container (5.3) such that the rotational speed of the outside of the test cylinder through the artificial seawater is (60 5) r/min (0,2 0,02) m/s. The devi

44、ce itself shall not be allowed to come into contact with the artificial seawater. 5.3 Release rate measuring container (see Figure 1), made of an inert material see Annex A, item A.2 b), of nominal capacity (2 0,2) litres, 120 mm to 150 mm in diameter and 170 mm to 210 mm high. The container shall b

45、e fitted with three evenly spaced baffles around the inside of the container to prevent swirling during test cylinder rotation. The baffles shall consist of circular rods of diameter 5 mm to 7 mm running from the bottom of the container to a level at least above that of the artificial seawater. They

46、 shall be fixed in place using an inert adhesive or solvent. There shall be a means of maintaining the container and its contents at (25 1) C. NOTE Placing the container in a thermostatically controlled water bath has been found to be a suitable means of maintaining the temperature at the correct le

47、vel; alternatively, the test may be performed in a conditioned room at the specified temperature. If the release rate of a highly photosensitive biocide is being determined, then the container shall be protected from natural and artificial visible-light sources. Details of this requirement to protec

48、t the container from light are indicated in the part of this standard relating to determination of the release rate of that biocide.
