Our flooring panels are produced and shaped in a manner that secures the resistance and stability required to adhere to our standards. All of our systems must adhere to NF EN 12825 and be certified by an official and independent testing body.
Our raised access floor tests (EN ISO 140-12) prove that our panels can reach a acoustic isolation between 44 and 54 dBA. The effective isolation depends heavily on the covering used. Textile covering is proven to have the best acoustic isolation properties.
The regulation of raised access flooring refers to:
Reaction to fire
Partitioning of plenum
The potential fire value
The performance of these tests varies depending on the room, as well as the classification of the building where the flooring is installed
The 30. June, 1983, France defined 5 levels of fire resistance for flammable materials: M0, M1, M2, M3 and M4. Radiation is the preferred method for testing.
When required by regulation, air dividers made of non-combustible materials can be supplied. Every partitioned area has a maximum surface area of 300m² and a maximum length of 30 meters. In case of fire, the partitioning limits the air circulation inside the plenum.
The ability of a covering to accumulate electrostatic loads, and its ability to eliminate these loads are essential for the antistatic properties of a raised access floor. The measurement of the transversal resistivity (T) enables the estimation of the ability to eliminate electrostatic loads.
The coverings are classified according to NF P 62.001 (Resilient floor coverings – Electrostatic behaviour)
Class 1 : Astatic covering : T > 1.109 ohms and electrostatic charging potential < 2 kV.
Class 2 : Dissipative covering : 1.107 ohms < T < 1.109 ohms and electrostatic charging potential < 2 kV.
Class 3 : Conductive covering : T < 1.107 ohms and electrostatic charging potential < 2 kV.
All raised access floors must have a transversal resistivity between 5.105 and 2.1012 ohms.
The equipotential connection is made by a copper strap network connecting certain pedestals to each other. This network is earthed by the companies in charge of the electrical wiring.
