Description of 21/30436227 DC 2021

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:

  1. they are mainly for architectural applications designed with mostly uniformly wall-thicknesses;

  2. they are mainly used for architecture, mechanical engineering and automotive applications (except structural-parts and crash-elements);

  3. the maximum weight per metre of 10 kg/m;

  4. the max. wall-thickness proportion (S max/S min) of 3,5 mm.

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).
