8.3.2.1: Change in level

Where there is a change in floor level that is integral to the ICT then it shall be ramped with a slope no steeper than 1:48.

Exceptions:

a) If the change in floor level is less than or equal to 6,4 mm (¼ inch) the change may be vertical as shown in Figure 1.

b) If the change in floor level is less than or equal to 13 mm (½ inch) the change may have a slope not steeper than 1:2 as shown in Figure 2.
