scope:

In many areas (e.g. automotive/industrial/synthetic coatings) the materials used are adapted to the specific application equipment and technologies of the user. Coating materials are, therefore, to be understood as semi-manufactured products that only receive their final form in combination with specific application methods and processes. This is decisive for quality evaluation of the finished product. The current procedure aims to define standards for evaluation of coatings in research, development and production with regard to their suitability and safety for industrial processes. The procedure is also concerned with fault analysis. As properties of coatings depend on thickness, coating systems of increasing thickness are applied to a test panel under predefined conditions. Film thickness is measured in accordance with ISO 2808. Depending on film thickness the following properties are then determined visually: - sagging; - boiling; - pinholes; - opacity.
