16、de federation of national standards bodies (ISO member bodies). The work of preparing International Standards 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 tha

17、t committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in a

18、ccordance 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 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard re

19、quires 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 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2085 was prepared by Techni

21、ISO 2085:2010(E) ISO 2010 All rights reserved 1Anodizing of aluminium and its alloys Check for continuity of thin anodic oxidation coatings Copper sulfate test 1 Scope This International Standard specifies a method for checking the continuity of thin anodic oxidation coatings on aluminium and its al

22、loys by a copper sulfate contact test. The use of this method is limited to anodic oxidation coatings of thickness less than 5 m, or coatings that have been deformed. NOTE The method described enables a rapid check to be made for the continuity of a thin coating of aluminium oxidation on aluminium a

23、nd its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating which exposes bare metal. 2 Principle Drops of copper sulfate reagent are placed on surface areas of

24、about 100 mm2, chosen at will on the test pieces, avoiding the anodizing contact areas. If the area includes points where the metal is either bare or poorly covered, chemical deposition of copper takes place on the aluminium, accompanied by a release of gas. The drops of applied reagent can be exami

25、ned immediately upon application, either with the naked eye or with a magnifying glass, for the release of gas from points where the metal is bare, which is almost instantaneous. After the test, black and/or dark reddish spots can be seen where the coating is not continuous. 3 Reagents 3.1 Copper su

26、lfate solution, prepared as follows: copper(II) sulfate pentahydrate, (CuSO45H2O): 20 g; hydrochloric acid (20= 1,18 g/ml): 20 ml; distilled water or deionized water: make up to 1 000 ml. 4 Procedure Carry out the test at room temperature. Remove all grease from the test piece. Mark out a test area

27、of approximately 100 mm2on a horizontal part of the test piece, using a wax crayon or a rapidly drying lacquer to delineate the test area, leaving the test area itself unmasked. Cover the test area with the reagent (3.1), using approximately four drops. Leave the reagent in contact with the surface

28、for 5 min, noting any release of gas, then rinse the area with clean water. Examine the surface and count the number of black and/or dark reddish spots per 100 mm2. BS EN ISO 2085:2010ISO 2085:2010(E) 2 ISO 2010 All rights reservedNOTE For a more quantitative measurement, the average diameter of the

29、 black and/or dark reddish spots can also be estimated. 5 Expression of results Record the number of black and/or dark reddish spots per 100 mm2for each area examined and, if appropriate, their average diameter. 6 Test report The test report shall include at least the following information: a) a ref

30、erence to this International Standard (ISO 2085:2010); b) the type and identification of the product tested; c) the results of the test (see Clause 5); d) anything unusual noticed during the determination; e) the date of the test.
