EN 311 is the test method for the surface soundness (pull-off strength) of wood-based panels. To match this to your program, talk with our team.
What EN 311 Covers
It measures how firmly the surface layer of a wood-based panel resists pull-off, relevant to overlaid and unfaced boards before finishing.
How the Test Is Run
A test dolly is bonded to the panel surface and pulled off perpendicular to the face, and the pull-off force gives the surface soundness.
Why It Matters
Surface soundness governs how well coatings and overlays adhere; a pull-off fixture and accurate normal loading are essential.
