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

Table 4. Ramp rises

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.
