10 Workstation Design
10.1 Standing station
#1
10.1.1 Work surface edge radius where the operator
can assume a static posture in contact with the
edge.
minimum 6.4 mm (0.25 in.) radius
10.1.2 Height of keyboard, trackball, or mouse (to
home row, top of ball/mouse).
NOTE: In applications where input devices
(keyboard, trackball, or mouse) are used more
like machine controls (intermittent one finger
entry on the keyboard, intermittent short term
use of the mouse or trackball) than for standard
typing (continuous use of keyboard for entry of
long character strings, extended use of trackball
or mouse in graphical environment), it is
appropriate to use the height and reach locations
described in §9, Hand Control Location
(standing station).
maximum 1020 mm (40 in.)
minimum 970 mm (38 in.)
10.1.3 Height of microscope eyepieces. Should be
adjustable through at least this range.
Range includes 1270 mm (50 in.) to
1730 mm (68 in.)
10.2 Seated station

10.2.1 Height of keyboard, trackball, or mouse. (to
home row, top of ball/mouse).

station).
maximum 760 mm (30 in.)
minimum 710 mm (28 in.)
10.2.2 Vertical leg clearance. minimum 673 mm (26.5 in.)
10.2.3 Horizontal leg clearance, depth at knee level. minimum 508 mm (20 in.)
10.2.4 Horizontal leg clearance, depth at foot level. minimum 660 mm (26 in.) depth ×

10.2.5 Horizontal leg clearance, width. minimum 610 mm (24 in.)
10.2.6 Height of microscope eyepiece. Should be
adjustable through at least this range.
Note: Assumes a 711 mm (28 in.) to 762 mm
(30 in.) worksurface.
Range includes 1220 mm (48 in.) to
1370 mm (54 in.)
10.2.7 Thickness of work surface. maximum 51 mm (2.0 in.)
10.2.8 Work surface edge radius where the operator
can assume a static posture in contact with the
edge.
minimum 6 mm (0.25 in.) radius
#1
A standing station is one where the operator can assume a standing posture or a seated posture in a tall stool which places the operator at
approximately the same stature.
#2
A seated station is one where a short cylinder office style chair is used.
#3
Distance measured away from the equipment or obstruction for body clearance in the given posture.
