LOAD CLASSES

All our Load tests have been made under SOCOTEC CONSULTING survey.

Definitions according to
European Standard EN 12825

Ultimate Load :

Maximum load got at the failure of the element during the ultimate load test procedure.

Working Load :

Load got when dividing the ultimate load by the safety factor.
The safety factor used by GAMMA and the majority of raised floors manufacturers is : 2

Requirement of European Standard EN 12825 :

Before failure, the element must have taken the ultimate load of its class, according to the following table :

LOAD CLASS	1	2	3	4	5	6
Ultimate load	> 4 kN	> 6 kN	> 8 kN	> 9 kN	> 10 kN	> 12 kN
Working load	> 2 kN	> 3 kN	> 4 kN	> 4.5 kN	> 5 kN	> 6 kN

When the load applied equals the working load, the deflection must not overtake the values of the following board :

Deflection class	Maximum deflection
A - ( the most stringent )	2.5 mm
B	3.0 mm
C - ( the least stringent )	4.0 mm

A system classed 1A is a system for which the ultimate load is at least 4 kN ( load class 1 ).

The working load of this system is at least 2 kN, with a safety factor of 2, for a deflection less than 2.5 mm (deflection class A).

See tables upper for the other classes.
