TAPPI-T 838 – Edge crush test using neckdown
Edge Crush (ECT)
ECT–Edge Crush Test measures the edgewise compression strength,parallel to the flutes
This method describes a procedure for determining the edgewise compressive strength, parallel to the flutes, of a short column of single-, double-, or triple-wall corrugated fiberboard, in a neckdown, non-reinforced, loading edge configuration.
