ISO 3035 is the test method for the flat crush resistance of corrugated fibreboard. To match this to your program, talk with our team.
What ISO 3035 Covers
It measures how much pressure the fluting of corrugated board withstands before the flutes collapse, indicating the quality and condition of the corrugated medium.
How the Test Is Run
A conditioned corrugated specimen is compressed flatwise between platens until the flutes crush, and the flat crush resistance is recorded.
Why It Matters
Flat crush indicates fluting quality and medium condition; flat, parallel platens and controlled conditioning are essential.
