1. If the yield point is not pronounced, the value applies to Rp0.2; if the yield point is pronounced, the value applies to Rel.
2. When the thickness is less than or equal to 0.7 mm and greater than 0.5 mm, the minimum value for elongation is reduced by 2 units. For a thickness less than or equal to 0.5 mm, the minimum value is reduced by 4 units.
