8.0 Display Location
NOTE: Angle-adjustable displays allow the user optimize the
viewing angle to control glare and maximize comfort.
8.1 Location for operator primary interface, standing station.
NOTE: A standing station is one where the operator can assume a
standing posture or use a tall stool or chair which places the
operator at approximately the same height as a standing
posture.
8.1.1 Height of video display terminal (single monitor). Does not include
touchscreens, measured from floor to center of screen.
Acceptance criteria: maximum 1470 mm (58 in.)
minimum 1320 mm (52 in.)
NOTE: The display user should be able to view a display while
maintaining a near-neutral posture.
Single monitor
Maximum 1470
mm
(58 in.)
Minimum 1320
mm
(52 in.)
8.1.2 Height of video display terminal (stacked monitors). Does not include
touchscreens, measured from floor to top line of the top monitor.
Acceptance criterion: maximum 1680 mm (66 in.)
The primary monitor in a stacked configuration is the bottom monitor.
Top stacked
monitor
Maximum 1680 mm
(66 in.)

8.1.3 Height of infrequently used video display terminal (viewed briefly less
often than once per hour) measured to top line of monitor.
Acceptance criterion: maximum 1680 mm (66 in.)
Infrequently used
monitor
Maximum 1680 mm
(66 in.)
8.1.4 Height of very infrequently used video display terminal (viewed briefly
less often than once per day) measured to top line of monitor.
Acceptance criterion: maximum 1880 mm (74 in.)
Very infrequently
used monitor
Maximum 1880
mm
(74 in.)
8.1.5 Height of infrequently viewed visual signal measured to the top of the
signal. This guideline does not apply to light towers.
Acceptance criterion: maximum 2130 mm (84 in.)
Visual signal height
Maximum 2130 mm
(
84 in.
)
8.1.6 Height of touch screen monitor.
Acceptance criteria: maximum 1470 mm (58 in.), measured from floor
to uppermost active pad on screen
minimum 910 mm (36 in.), measured from floor to
lowest active pad on the screen.
See §9 for horizontal reach criteria.
NOTE: Touch screen design recommendations also apply to light pen
operated systems.
Top of active area
Maximum height
1470 mm (58.0”)
Bottom of active
area
Minimum height
910 mm (36.0”)
8.1.7 Tilt angle of touch screen monitor between 41 and 48 inches in height to
top of screen.
Acceptance criterion: upward minimum 30 degrees
NOTE A: Angle adjustment is recommended to accommodate users of
varying heights and to reduce glare under different lighting
conditions.
NOTE B: The angle of visibility for flat panel display touch screens
varies depending upon which display technology is used
(e.g., passive vs. active matrix) so providing angle
adjustment will allow users to set the display angle for
maximum visibility and comfort.
8.1.8 Tilt angle of touch screen monitor less than 41 inches in height to top of
screen.
Acceptance criterion: upward minimum 45 degrees
