Aluminium and aluminium alloys - Forgings - Part 3: Tolerances on dimensions and form

Scope

This European Standard specifies the tolerances on dimensions and form of aluminium and aluminium alloy forgings for general engineering applications of usual design concepts which are formed hot.
It applies to :
¾ die forgings without machining all over :
shape dimensions nmax £ 2 000 mm, die closure dimensions tmax £ 600 mm and projected area A £ 4 000 cm²;
die forgings with machining all over :
shape dimensions nmax £ 6 000 mm and projected area A £ 22 000 cm²;
¾ hand forgings :
profile dimensions nmax £ 8 000 mm.
Tolerances on forgings outside the scope of this standard or of complex design can be mutually agreed between supplier and purchaser.
Design guidelines for die and hand forgings are given in annex A.
NOTE Some of the products mentioned in this European Standard may be the subject of patent or patent applications, and their listing herein is not to be construed in any way as the granting of a licence under such patent right.
CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses on standardized standards products under resonable and non discriminatory conditions then this product should be removed from the corresponding standard.
