ISO 28199-1:2009(E) iv © ISO 2009 – All rights reserved 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 member 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 Electrotechnical 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 adopted 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. ISO 28199-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. ISO 28199 consists of the following parts, under the general title Paints and varnishes — Evaluation of properties of coating systems related to the application process: ⎯ Part 1: Relevant vocabulary and preparation of test panels ⎯ Part 2: Colour stability, process hiding power, re-dissolving, overspray absorption, wetting, surface texture and mottling ⎯ Part 3: Visual assessment of sagging, formation of bubbles, pinholing and hiding power SIST EN ISO 28199-1:2010

ISO 28199-1:2009(E) © ISO 2009 – All rights reserved v Introduction In many areas (e.g. car manufacture, industrial coatings, coatings for plastics) the coating materials used are adapted to the specific application equipment and technologies of the particular user. A coating material is, therefore, to be understood as a semi-manufactured product that only receives its final form in combination with the specific application conditions. The adaptation to the application conditions is therefore decisive for the quality of the coated product. The test methods specified in ISO 28199 are based on studies by a Working Group of the European Council for Automotive R&D (EUCAR). They may be used for evaluation of coating materials in research, development and production with regard to their suitability and safety for industrial processes, and error analysis. The properties of coating materials and coatings to be evaluated depend on the film thickness, so a coating system of increasing thickness is applied to a test panel under defined conditions. The following characteristics are measured (in this part of ISO 28199): ⎯ film thickness in accordance with ISO 2808; ⎯ surface texture; ⎯ colour in accordance with ISO 7724 (all parts). In combination with visual assessment, the following properties are determined: ⎯ colour stability, process hiding power, re-dissolving, overspray absorption, wetting, surface texture and mottling (ISO 28199-2); ⎯ tendency toward sagging, formation of bubbles, pinholing and hiding power (ISO 28199-3). The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning the locally related measurements used in Version A in Clauses 8 and 9. ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured ISO that he is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with ISO. Information may be obtained from: DuPont Performance Coatings GmbH Postfach 20 02 44 42271 Wuppertal Germany Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 28199-1:2009(E) 2 © ISO 2009 – All rights reserved 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 bubble closed or already burst blister in a layer, arising when solvents or cleavage products evaporate too rapidly NOTE If bubbles are caused by the process control and/or the formulation components, the viscosity of the paint film has increased too rapidly during the drying phase so that solvents/reaction products still in the paint film have built up at the polymer paint skin which forms, usually resulting in closed blisters and sometimes resulting in burst blisters. 3.2 bubble formation limit first appearance of continuous bubbles in the measuring area NOTE A single bubble does not define the bubble formation limit. Bubbles at the edge of the measuring area and in the perforated area of the panel (see Figure 2) should not be taken into account. 3.3 colour stability non-variability, or variability within agreed tolerances, of colour despite variation of influencing factors NOTE Examples of influencing factors are thickness and application method. 3.4 cratering formation in a film of small circular depressions that persist after drying [ISO 4618:2006] NOTE 1 Craters can extend as far as the next lower layer. NOTE 2 Craters are caused by local inhomogeneities in the surface tension of the coating, most frequently due to incompatible contamination substances on the substrate, in the applied coating material or in the form of foreign particles or small oil drops. 3.5 locally related measurements measurements of film thickness and optical surface property which are taken at the same point, i.e. within a radius of < 10 mm 3.6 locally unrelated measurements measurements of film thickness and optical surface property which are not taken at the same point, i.e. within a radius of W 10 mm 3.7 minimum film-build lowest thickness at which a coating material forms a continuous film on a substrate 3.8 mottling non-uniform appearance of a film caused by presence of irregularly shaped, randomly distributed areas on the surface that vary in colour and/or gloss [ISO 4618:2006] SIST EN ISO 28199-1:2010
