This document specifies a non-waxed edge method for the determination of the edgewise crush resistance of corrugated fibreboard. The force is applied in the direction of the flute axis. This method is applicable to single-wall (double-faced), double-wall, and triple-wall corrugated fibreboard. It is applicable to all corrugated fibreboard flute types if no buckling and/or tipping occurs during measurement. This method is also applicable to test samples taken from corrugated cases and other converted products.
