The wood and furniture industry, glulam and log industry and the window and exterior door industry require various kinds of testing, which we can offer. Our quality control tests are mainly based on standards EN 14080, EN 15497 and EN 16351.
Gluing strength testing
- Tensile shear strength in the temperature range -70…+100°C, up to 10 kN
- Tensile shear strength +20…+250°C, up to 50 kN
- Compressive shear strength at +20°C, up to 50 kN
- 4-point bending test at +20°C, up to 50 kN (to measure the strength of a finger joint, for example)
The test is specifically designed for window and door scantlings in which D4 grade or PVAC adhesives are used. In the test, the items are subjected to stress under water and subsequently dried in a climate chamber. Any cracks are analysed and reported according to instructions.
Delamination test for door and window frames and other non-structural wood bonds
The test is designed for scantlings glued with EPI and PVAC adhesives (type II adhesives). This is a delamination test in which a glued piece of wood is stress tested in under- and overpressure in a water-filled pressure vessel, then dried in a climate chamber. Any cracks in the adhesive joints are analysed and reported according to the standard.
Delamination test for laminated logs, glulam and CLT products and other structural adhesion
The test is designed for supporting wood structures glued with type I adhesives (such as EPI, PUR or MUF). This is a delamination test, according to standards EN 14080 (laminated log and glulam) or EN 16351 (CLT) in which a glued piece of wood is stress tested in under- and overpressure in a water-filled pressure vessel, then dried in a climate chamber. After the test, any cracks in the adhesive joints are analysed and reported to the customer.
Stress tests for the parquet industry
Quality control cycles for the parquet industry, such as cooking in boiling water and drying.
Furniture testing in a climate chamber, such as for D3-level adhesion
-20…+100°C, 0–100% relative humidity test cycles for furniture and exterior doors. Test cycles tailored according to the customer’s needs.
Peeling test, strength test of film coating adhesion
T-peel or 90° peel tests for coatings glued on wood-based material.
