8.3.2.6: Knee clearance

Where an obstacle is integral to the ICT, the space under the obstacle that is between 230 mm and 685 mm above the floor is considered knee clearance and should:

a) extend no more than 635 mm (25 inches) under the obstacle at a height of 230 mm (9 inches) above the floor;

b) extend at least 280 mm (11 inches) under the obstacle at a height of 230 mm (9 inches) above the floor;

c) extend at least 205 mm (8 inches) under the obstacle at a height of 685 mm (27 inches) above the floor;

d) be between 230 mm (9 inches) and 685 mm (27 inches) above the floor be permitted to be reduced in depth at a rate of 25 mm (1 inch) for each 150 mm (6 inches) in height.

This is shown in Figure 7.
