1) Reduced minimum values of elongation at rupture apply to product thicknesses t < 0.60 mm (minus 2 units).
2) For ZF-coated, products the minimum values of elongation at fracture are reduced by 2 unites.
For ZF-coated in thicknesses t < 0.60 mm, the minimum elongation at rupture is reduced by 4 units.

* Comparative grade, therefore minor deviations from DIN EN values possible
