5. The ground pavement cannot have loose elements and must allow for movement or
dragging.

6. Rugs and carpets shall be firmly fixed to the floor and shall allow easy movement for
wheelchair users.

7. Floor pavement shall not produce glare.

8. The pavement shall present reflectance contrast with the surrounding pavement of
at least 30 points LRV (Light Reflectance Value), or by an easily perceptible (by the
foot or the cane) texture difference. These pavements can present less contrast if
they are separated by a pavement strip of at least 300 mm presenting the required
contrast or by an easily perceptible texture difference.

9. Lighting installed in floors is not permitted if it produces glare in the area of
accessible paths.

10. Lighting installed in floors shall not produce heat.

11. Imperfections or irregularities in the floor surface that imply a level difference of more
than 5 mm or holes of more than 15 mm diameter are not allowed. These level
differences can be generated due to the material selection or because of a lack of
maintenance. This especially includes manhole covers grids and grills installed in
public spaces.

12. Changes in level of maximum 15 mm should be designed with a 25% maximum
gradient slope.

13. When grate openings are longitudinal, they should have a perpendicular orientation
to the pedestrians’ direction of travel.
