This test evaluates the ability of corrugating medium to contribute to the compression strength of a
corrugated box. It is a procedure for measuring the edgewise compression strength of a laboratory-fluted strip of corrugating medium in a direction parallel to the fluted tips.
edge crush is also measured in TAPPI T 824 ?Fluted edge crush of corrugating medium (flexible beam method)?, which uses a flexible beam compression machine instead of a rigid platen machine as used in this procedure.
