1. If the yield point is not pronounced, the value applies to R_p0.2; if the yield point is pronounced, the value applies to R_el.
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.
