DESCRIPTION

BS EN 12020-2:2022 - TC


This standard BS EN 12020-2:2022 - TC Tracked Changes. Aluminium and aluminium alloys. Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 is classified in these ICS categories:
  • 77.150.10 Aluminium products
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. NOTE The effect of the thermal barrier material on the dimensional tolerances is covered by this document although the actual thermal barrier material itself is not (see EN 14024).
