TAPPI T 843 – Fluted edge crush of corrugating medium (rigid support method)

TAPPI T 843 om-20 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.

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.
