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.
