18、on 8 Bibliography . 9 EN ISO 15181-1:2007iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each membe

19、r 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 part in the work. ISO collaborates closely with the International Elec

20、trotechnical 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 prepare International Standards. Draft International Standards adopt

21、ed 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 that some of the elements of this document may be the subject of paten

22、t rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15181-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This second edition cancels and replaces the first edition (IS

23、O 15181-1:2000), which has been technically revised, in particular to extend the use of the general extraction method to the later parts of ISO 15181. ISO 15181 consists of the following parts, under the general title Paints and varnishes Determination of release rate of biocides from antifouling pa

24、ints: Part 1: General method for extraction of biocides Part 2: Determination of copper-ion concentration in the extract and calculation of the release rate Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the concentration of ethylenethiourea in

25、 the extract Part 4: Determination of pyridine-triphenylborane (PTPB) concentration in the extract and calculation of the release rate Part 5: Calculation of the tolylfluanid and dichlofluanid release rate by determination of the concentration of dimethyltolylsulfamide (DMST) and dimethylphenylsulfa

26、mide (DMSA) in the extract EN ISO 15181-1:2007vIntroduction By 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

27、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 environment will, however, depend on many factors, such as ship operating schedules, length of service,

28、 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 release rates for antifouling products and are not suitable for direct use in the process of genera

29、ting environmental-risk assessments, producing environmental-loading 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 fro

30、m 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 biocides under in-service conditions. Published results demonstrate that the results of this test method are general

31、ly 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 relationship is expected to be found for other biocides. Realistic estimates of the biocide release r

32、ate 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 generating environmental-risk assessments, producing environmental-loading estimates or for regulato

33、ry 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 release rate from antifouling coatings under real-life conditions to be obtained. This can be acc

34、omplished through the application of appropriate correction factors2. EN ISO 15181-1:2007blank1Paints and varnishes Determination of release rate of biocides from antifouling paints Part 1: General method for extraction of biocides 1 Scope This part of ISO 15181 specifies a general method for extrac

35、ting 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 biocides in the extract, for example copper and/or certain organic biocides, and to enable the r

36、elease 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 application of this document.

42、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 defined period in individual release rate measuring containers containing the same artificial seawater be

43、fore 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 defined time intervals and hence the release rate of the biocide under the specified laboratory cond

44、itions 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 method given in this part of ISO 15181 to be carried out. 5 Apparatus NOTE Some biocides have a strong ten

46、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 device itself shall not be allowed to come into contact with the artificial seawater. 5.3 Release rate me

The container shall be fitted with three evenly spaced baffles around the inside of the container to prevent swirling duri

48、ng 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 shall be fixed in place using an inert adhesive or solvent. There shall be a means of maintaining th

49、e 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 level; 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.
