For products of width greater than 30 mm, it is measured at any point at least 10 or 15 mm from the longi

The requirements of 7.1.1.3 are not applicable at the beginning and the en

36、assing through the two ends of the reference measuring length (2500 mm). The straightness shall be measured on the concave side of the product and, for coils, outside any end tongue area (see figure i).
