1) Where no yield strength is defined, the respective values shall apply to the 0.2 % proof stress Rp0.2, otherwise for the lower yield strength (ReL). For thicknesses ≤ 0.7 mm, but > 0.5 mm, the maximum yield strength may be 20 MPa higher, and for thicknesses ≤ 0.5 mm 40 MPa.

2) For thicknesses ≤ 0.7 mm but > 0.5 mm, the minimum elongation at fracture may be 2 units lower. For thicknesses ≤ 0.5 mm, the minimum elongation at fracture may be 4 units lower.

3) The r90 and n90 values shown apply to product thicknesses ≥ 0.5 mm only.

4) For thicknesses > 2 mm, the r90 value is reduced by 0.2.
