Where the flooring elements are laid directly onto a concrete or stable base, then the point loading increases as follows:

• 2E11 - 3.0kN
• 2E22 - 4.0kN

Ranges of use and application

1	Premises and corridors in buildings for habitation, hotel bedrooms with bathrooms.
2	Offices and corridors, surgeries including wards and waiting rooms and corridors ≤ 50 m2 adjacent to an apartment, office or similar buildings.
3	Corridors in hotels, retirement homes and boarding schools or similar buildings. Treatment and operating rooms not containing any heavy equipment.
3	Areas containing tables such as classrooms, cafés, restaurants, dining rooms, lecture halls and reception lounges.
4	Corridors in hospital buildings, retirement homes, treatment rooms and operating rooms containing heavy equipment.
4	Areas intended for large gatherings of people, for example: classrooms, auditoria, churches, theatres, cinemas, conference rooms, waiting rooms, concert halls.
4	Large open areas, for example: museums, exhibition halls, entrances to public buildings and hotels.
4	Sports and leisure halls, for example: dance halls, gymnasia, fitness rooms, stages, specialist shops and superstores.

The addition of extra layers does not restrict the range of use and does not change the resistance to concentrated loads. If the flooring elements are laid on top of a concrete slab, the allowable concentrated load rating increases to 2.5 kN for the 2E11 flooring elements and to 3.5 kN for the 2E22 flooring elements. The scope of use extends to field 3 for 2E11 and to field 4 for 2E22.
