1) Where no yield strength is defined, the respective values shall apply to the 0.2 % proof stress (Rp0.2) or to the lower yield strength (ReL).
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 apply to product thicknesses ≥ 0.5 mm only.
4) For thicknesses > 2 mm, the r90-value is reduced by 0.2.
