| Subject of the standard: | This document specifies tolerances on dimensions and form of extruded precision profiles in alloys EN AW-6060 and EN AW-6063, manufactured with and without a thermal barrier (see Figures 1 and 2). It applies to extruded products supplied without further surface treatment. Precision profiles covered in this document are distinguished from extruded profiles for general applications covered in EN 755-9 by the following characteristics: - they are designed with mostly uniform wall-thicknesses; - they are mainly used for mechanical engineering, architectural and automotive (except crash-elements) applications; - their maximum weight per metre is 10 kg/m; - their maximum wall thickness ratio (tmax/tmin) is 3,5. In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, then special agreements between supplier and purchaser may need to be reached. |
