The tolerances applied for the pressed heads are defined according to the applicable norms (particularly the norm AFNOR NF E 81-100).
For the rolled heads are as follows:
On the external diameter:
< Ø 2000 = ± 2 ‰ • Ø
> Ø 2000 = ± 3 ‰ • Ø
Ovality
(difference between the minimum diameter and the maximum diameter):
± 3 ‰ • Ø
Total height
(for heads with raw edge):
-0 + 25mm

SHEETS
The tolerances of dimensions and shape of the sheets to be used for reference, unless otherwise agreed, are in accordance with UNI EN 10025 and UNI EN 10051.
