Flat crush test is designed to measure the resistance of corrugated paperboard to flute crushing. This is a very useful measurement when determining the amount of pressure applied during the printing process for corrugated boxes, for example. The test follows the same basic procedure as the edge crush test described above except that the sample is a different size and orientation.
