TAPPI-T 824 – Fluted edge crush of corrugating medium (flexible beam method)
Concora Crush (CCT)
CCT-Corrugated Crush Test measures the edgewise compression strength of a laboratory-fluted strip of corrugating medium in the direction parallel to the fluted tips
Fluted edge crush of corrugating medium (rigid support metho, Test Method T 843 om-14)
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.
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.
