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).
