Corrugating medium - Determination of the flat crush resistance after laboratory fluting - Part 1: A-flute (ISO 7263-1:2018)
This document describes a method for the determination of the flat crush resistance of a corrugating medium after laboratory fluting using an A-flute geometry. The procedure is applicable to any corrugating medium intended to be used, after fluting, in the manufacture of corrugated board. NOTE ISO 7263-2 describes a method to determine the flat crush resistance using a B-flute geometry.
