1. Scope

1.1 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.

1.2 Fluted 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.
