1) Where the yield strength is defined, the respective values shall apply to the lower yield strength (R_eL).

2) Depending on the product thickness, the minimum values of elongation at fracture are reduced as follows: 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) For AS, AZ, ZF and ZM coatings, the minimum A₈₀ value is reduced by 2 units and the minimum r₉₀ value by 0.2.

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.
