Flat Crush Tester for Corrugated Fluting Medium

Flat compression tester that measures the resistance of corrugated flutes to being flattened under load. Used by corrugators and board mills to verify medium quality and flute formation.

Specification

A board specimen of 100 cm2 is compressed between two flat platens at 12.5 mm per minute until the flutes collapse, and the maximum force gives the flat crush resistance. The test indicates how well the board resists crushing in the corrugator and conversion. Both corrugated board and CMT specimens can be tested.
