Tolerance on outer diameter D:

Outer diameter D≤168.3, Tolerance class D3, Allowed deviation +/-0.75% or +/-0.3mm. Whichever is bigger.
Outer diameter D≤168.3, Tolerance class D4*, Allowed deviation +/-0.5% or +/-0.1mm. Whichever is bigger.
Outer diameter D>168.3, Tolerance class D2**, Permissible deviation +/-1.0%.

*Tolerance class D4 if necessary against special manufacturing only and at extra cost.
**Tolerance class D2 on all pipes with a D to T ratio below 10:1 and press-formed pipes Stos tolerances are guaranteed only on pipe ends.

Wall thickness tolerance T:

Tolerance class T3, Permissible deviation +/-10% or +/-0.2mm. whichever is greater.
