5.7.  Ramps


               Ramps should be used when a change in level has a gradient greater than 5%.


               The maximum slope is 8% or 1:12.


               The maximum cross fall gradient is 2%.


               The slope of a ramp must meet the following specifications:



                Maximum Rise                      Slope                    Length between landings

                                    Recommended          Maximum        Recommended           Maximum


                    1500 mm            5,1% - 6%             8%             7 meters          10 meters

                    1000 mm               ≤ 7%               8%             5 meters           7 meters


                     500 mm               ≤ 8%               8%             2 meters           5 meters

               5.7.1.      Ramp runs

               Ramp runs shall fulfil the following requirements:


               1.  The maximum length is 10 meters between landings.


               2.  The beginning and the end of each ramp run shall have a warning surface following
                   the requirements of section 5.3.

               3.  The run usable width shall be 1000 mm.

               4.  Ramp widths shall be free of obstacles. The usable width of 1000 mm is measured
                   between the handrails. If the ramp is open, it shall have an outside edge protection
                   or a lateral protection element of at least 100 mm in height.


               5.  Curved ramps are not permitted.
