Laboratory for Physical Properties Testing
How will you characterise your papers and boards?
- Structural tests
- Optical properties
- Mechanical strength
- Air permeability, absorption of liquids
- Smoothness, roughness, wear
General informations
Our laboratory holds COFRAC Testing accreditation no. 1-0552 (scope available at www.cofrac.fr) as per the ISO 17025 standard.The physical properties testing laboratory operates as follows:
- On request
- In the context of determining compliance with specifications, standards, regulations
- Comparative analyses of products,
- Quality control monitoring of paper and board and/or finished products
- Expert appraisals of products
- On receipt of samples
- After pre-conditioning and standardised conditioning
- After variable conditioning
- Following an artificial ageing cycle (temperature, moisture, cold or light).

Équipments
- Optical devices with a variety of geometries, light sources and observation conditions
- Instruments for measuring properties such as surface, smoothness and roughness or topography or for characterising textured or braille-embossed papers and boards
- Permeability measurement apparatus
- Instruments for measuring the mechanical properties of papers and boards
- Apparatus for measuring dimensional stability (Varidim), compressive strength (Varipress) and curl of papers under variable humidity conditions
- Apparatus for measuring sheet formation and for determining tensile stiffness indices and fibre orientation
- Climate-controlled chambers with adjustable temperature and humidity; light fastness testers
- Specific instruments for corrugated board: ECT, FCT, RCT, CCT, glue line strength
- Specific instruments for papers and tissue products: thickness, water absorption capacity, ball burst, softness, dispersion, disintegration in water.
Observing the quality of a crease
Accredited tests
The scope of our accreditation covers some twenty paper and board tests:
- Structure: grammage, thickness and moisture content of paper and board
- Mechanical strength: burst of papers, boards and corrugated boards, tearing resistance, tensile strength, static and dynamic bending resistance, folding endurance, short-span compressive strength
- Absorption of water - gluing: water absorption capacity, Cobb method, sizing/writing degree
- Smoothness, permeability: Bekk smoothness, Bendtsen roughness, Bendtsen permeability
- Optical properties: brightness, whiteness, opacity, colour.
