Wood Industry & Construction Testing
Info COVID-19
Throughout this reconfinement period, our laboratories remain open and our testing activities are maintained.
You can continue to send your test samples to the respective sites.
Anatomy, wood and packaging
- Identification of temperate and tropical wood species
- Characterisation of wood species for the determination of its mechanical class (stress, modulus of elasticity, nodosity, density, moisture content by destructive and non-destructive testing)
- Approval of wood grading machines
- Mechanical tests on all types of pallets
- Tests on all types of packaging used for the transport of goods
Mechanical and seismic
Static and cyclic tests
These tests are carried out on wood-based construction elements within the framework of normative requirements (Eurocode 5, CE marking, technical opinion, etc.)
Mechanical tests are carried out on all types of construction elements (decking and cladding boards, etc.)
Tensile, flexural, compressive, shear and torsional stresses from the test specimen to the full-scale element (timber frame walls, LC beams, trusses, floors, porticos, stairs, balustrades, joinery strips, timber/insulation combinations, etc.)
Ageing cycle tests (delamination) and service life tests
Evaluation of mechanical connectors (pins, screws, lag bolts, connectors, brackets, etc.)
Mechanical evaluation of thermal or complex insulation (creep, dynamic stiffness, compressive and tensile strength)
Seismic testing of structural elements
Modal analysis (resonance frequency, damping, modal deformation)
On-off strength tests
Cyclic and dynamic tests
Video measurement
Characterising products or systems
Finite element modelling
Acoustics
The tests are carried out in three cells differentiated by colours
Blue cell
Measurement of airborne sound insulation:
– tests on partitions, walls, facades, motorway motorway screens.
-Tests on floor coverings, floors, roofs, etc.
Measurement of sound insulation against impact noise
– tests on floor coverings, floors, etc.
Measurement of the sound of walking on floor coverings
Measurement of the apparent dynamic stiffness of subfloors
Yellow cell
Measurement of sound absorption in a reverberation chamber
– tests on wall, floor and ceiling coverings and motorway screens.
– tests on furniture (screens and office partitions, chairs, etc.).
Red cell

doors, door units, roller shutter boxes and panels/
glazing

Joinery
Air, Water, Wind, Mechanical (AWWM)
The tests are carried out on windows, patio doors and door units or walls/partitions for
Air permeability, watertightness and wind resistance (tests can also be carried out can also be carried out on the manufacturer’s premises)
Mechanical tests : bracing, buckling, safety
