DIN EN 12020-2 PDF

This document specifies tolerances on dimensions and form of extruded precision profiles, in alloys EN AW and EN AW 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 standard are distinguished from extruded profiles for general applications covered in EN by the following characteristics: they are mainly for architectural applications; they meet more stringent requirements regarding the surface condition of visible surfaces; the maximum diameter of the circumscribing circle CD is mm; they are made to closer tolerances on dimensions and form. 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

Tolerances for aluminium profiles (DIN EN 12020-2 : 2001-07)*

There are no general rules for what shapes and tolerances that can be applied in each case. Shape, wall thickness and alloy will have influence on the achieved tolerances. Narrow tolerances can reduce the productivity of the profile and thus the cost. This has to be taken into consideration when designing the profile. In this handbook, you will find an extract of these standards. Text and values are taken from there.
