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).

2) Reduced minimum values of elongation at fracture apply to product thicknesses 0.50 mm < t < 0.70 mm (minus 2 units), 0.35 mm < t < 0.50 mm (minus 4 units), and t < 0.35 mm (minus 7 units).

3) The maximum yield strength for surface class A is Re = 360 MPa.

4) For product thicknesses of 1.5 mm < t < 2 mm, the minimum r90 value is reduced by 0.2, and for t ≥ 2 mm by 0.4.

5) Depending on the product thickness, the minimum r90 value is reduced as follows: 0.50 mm < t < 0.70 mm by 0.2; 0.35 mm < t < 0.50 mm by 0.4, and t < 0.35 mm by 0.6.

Also depending on the product thickness, the minimum n90 value is reduced as follows: 0.50 mm < t < 0.70 mm by 0.01; 0.35 mm < t < 0.50 mm by 0.03, and t < 0.35 mm by 0.04.
