17、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 member body interested in a subject for which a technical
18、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 Electrotechnical Commission (IEC) on all matters of elect
19、rotechnical 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 adopted by the technical committees are circulated to the
20、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 patent rights. ISO shall not be held responsible for ident
21、ifying any or all such patent rights. ISO 2931 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 2, Organic and anodic oxidation coatings on aluminium. This third edition cancels and replaces the second edition (ISO 2931:1983), which has been technically r
22、evised. BS EN ISO 2931:2010ISO 2931:2010(E) ISO 2010 All rights reserved vIntroduction The test described in this International Standard is intended to give a quick, non-destructive assessment of the quality of sealed anodic oxidation coatings and is very suitable for routine production control. It
23、is carried out following sealing and before any other supplementary process is undertaken, for example, oiling, waxing or lacquering. The correlation of the results obtained with those of other sealing tests may be affected by the presence of sealing additives, or contaminants such as silicate or ph
24、osphate. For this reason, sealing quality is checked from time to time by one of the reference acid-dissolution methods specified in ISO 3210. The pretreatment, the anodizing process, the colouring process used and the alloy can all have an effect on admittance readings. BS EN ISO 2931:2010BS EN ISO
