1) For products that do not have a clear yield point, the values ​​for the 0.2% yield point (R p0.2 ) apply to the values ​​for the yield point, for other products the values ​​for the lower yield point (R eL ) apply. For thicknesses ≤ 0.7 mm, but > 0.5 mm, maximum values ​​for the yield point that are 20 MPa higher are permissible. For thicknesses ≤ 0.5 mm, maximum values ​​for the yield point that are 40 MPa higher are permissible.

2) For thicknesses ≤ 0.7 mm, but > 0.5 mm, minimum elongation at break values ​​that are 2 units lower are permitted. For thicknesses ≤ 0.5 mm, minimum values ​​lower by 4 units are permissible.

3) The r 90 and n 90 values ​​only apply to product thicknesses ≥ 0.5 mm.

4) For thicknesses > 2 mm, the r 90 value is reduced by 0.2.
