BS EN 12020-1:2008 Aluminium and aluminium alloys. Extruded precision profiles in alloys EN AW-6060 and EN AW-6063. Technical conditions for inspection and delivery
BS EN 12020-1 is the European standard that specifies the technical conditions for inspection and delivery of alloys BS EN AW-6060 and BS EN AW-6063 extruded precision profiles manufactured with and without a thermal barrier and without further surface treatment.
Precision profiles covered in this document are distinguished from extruded profiles for general applications covered in BS EN 755-9 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 350 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.
The effect of the thermal barrier material on the dimensional tolerances is covered by BS EN 12020-2 although the actual thermal barrier material itself is not (see BS EN 14024).
