ISO-7263 – Corrugating medium – Determination of the flat crush resistance after laboratory fluting
Flat Crush Test (FCT)
Flat Crush Test measures the resistance of the flutes to a crushing force applied perpendicular to the surface of the board under prescribed conditions
ISO 7263:2011 specifies two methods for the determination of the flat crush resistance of a corrugating medium after laboratory fluting.
The procedures are applicable to any corrugating medium intended to be used, after fluting, in the manufacture of corrugated board.
