BS EN 12020-2:2001

This European Standard, a part of the BS EN 12020 series, specifies tolerances on dimensions and form of extruded precision profiles, in alloys BS EN AW-6060 and BS EN AW-6063 manufactured with and without a thermal barrier.

BS EN 12020-2:2001 specifies requirements for extruded products supplied without further surface treatment. Precision profiles covered in this standard 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 300 mm
• they are made to closer tolerances on dimensions and form.
