ISO 15754 (Paper & board): Z-directional tensile strength (ZDT) test
ISO 15754 is the test method for the z-directional tensile strength of paper and board, the through-thickness bond strength. To match this to your program, talk with our team.
What ISO 15754 Covers
It measures how strongly the layers of paper or board are bonded through the thickness, important for delamination resistance in printing and converting.
How the Test Is Run
A specimen is bonded between platens and pulled apart perpendicular to the sheet, and the z-directional tensile strength is calculated from the failure load and area.
Why It Matters
Z-direction strength governs internal bond and delamination resistance; flat, parallel bonding surfaces and accurate force measurement are needed.
