This document specifies a non-waxed edge method for the determination of the edgewise crush resistance of corrugated fibreboard. It is applicable to all corrugated fibreboard grades from K to D, including manufacturers specification grades of the similar dimensions. For E grades it is applicable if no buckling and/or tipping occurs during measurement. Under the defined test piece dimensions, grades finer than E are excluded, since they are not measurable due to buckling and tipping.
