Corrugated Component Testing

Basis Weight Testing: TIS 0308-01 Soak Method is the procedure used to analyze a specimen of corrugated fiberboard to determine the basis weights and calipers of the combined board and its components.

Cobb Testing: ISO 535:1991(E) specifies a method of determining the water absorptiveness of corrugated fiberboard under standard conditions.

Mullen Burst Test: T810 om-98 is the procedure used to measure the bursting strength of singlewall and doublewall corrugated and solid fiberboard.

T 839 pm-95: It is the procedure used to determine the edgewise compressive strength, parallel to the flutes, of a short column of singlewall or doublewall fiberboard.

Pin Adhesion Testing: T 821 om-96 is used to measure the force required to separate corrugated board between the flute tips of corrugated medium and its linerboard facings.
