EN 320 is the test method for the axial screw withdrawal resistance of particleboards and fibreboards. To match this to your program, talk with our team.
What EN 320 Covers
It measures the force needed to pull a screw straight out of a wood-based panel, indicating how well the panel holds fasteners for furniture and construction.
How the Test Is Run
A screw is inserted to a defined depth in a panel specimen and pulled axially at a controlled rate until it withdraws, and the maximum force is recorded.
Why It Matters
Screw withdrawal resistance governs fastener holding in panels; a withdrawal fixture and accurate force measurement are used.
