ÖNORM EN 12020-1

This document specifies technical conditions for inspection and delivery of alloys EN AW-6060 and EN AW-6063 extruded precision profiles manufactured with and without a thermal barrier (see Figures 1 and 2) and without further surface treatment. Precision profiles for which this document is applicable 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; - the maximum weight by meter is 10 kg/m; - the max. wall-thickness proportion (tmax/tmin) of 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.
