charge d’exploitation admissible du plancher

Eurocode 1: Actions on structures - Part 1-1: General actions -
Densities, self-weight, imposed loads for buildings
:
3.3 Charges d'exploitation
3.3.1 Généralités
(1) P Pour les surfaces devant supporter différentes catégories de charges, le dimensionnement doit considérer le cas de charge le plus critique.
(2) P Dans les situations de projet dans lesquelles les charges d'exploitation agissent en même temps que d'autres actions variables (actions dues au vent, à la neige, aux grues ou aux machines, par exemple), les charges d'exploitation totales incluses dans le cas de charge doivent être considérées comme une action unique.
(3) Lorsque le nombre de variations de charge ou les effets des vibrations peuvent provoquer des phénomènes de fatigue, il convient d'établir un modèle de charge de fatigue.

Note: Categorie C3 shows 3,0 à 5,0 kN/m², i.e. 5,000 N/m²

Is this a decimal error?

Thanks to Cyril we have another confirmation from Eurocode EN 1991

Eurocode 1: Actions on structures - Part 1-1: General actions -
Densities, self-weight, imposed loads for buildings

1 General
Section 3 Design situations
(l)P The relevant permanent and imposed loads shall be determined for each design
situation identified in accordance with EN 1990, 3.2.
:
3 Imposed loads
3.3.1 General
(l)P For areas which are intended to be subjected to different categories of loadings the design shall consider the most critical load case.
(2)P In design situations when imposed loads act simultaneously with other variable actions (e.g actions induced by wind, snow, cranes or machinery), the total imposed loads considered in the load case shall be considered as a single action.

Here is a useful link with both EN and FR eurocodes

Table 6.2 shows the 500kg/m2 of your source text (ie imposed loads on floors in EN, charges exploitables sur les planchers in FR)

As Sandra has already suggested, the maximum accepted weight for the exhibition floor is 500 kg per square metre of floor space.

Floor load capacity is the total maximum weight a floor is engineered to support over a given area. In the U.S. it is expressed as pounds per square foot. Floors are engineered to carry a maximum static load and a maximum dynamic load that can't be exceeded without the risk of compromise to the structure.
