touchscreens, measured from floor to centerline of monitor.
Acceptance criteria: maximum 1190 mm (47 in.)
minimum 940 mm (37 in.)
NOTE A: The display user should be able to view a display while
maintaining a near-neutral posture.

8.3 Display characteristics
8.3.1 Lateral distance from the centerline of the display to the centerline of the
input device(s).
Acceptance criterion: maximum 320 mm (12.6 in.)
NOTE: If several input devices are used (i.e. keyboard and mouse)
the centerline of the input device farthest from the display
should be measured.

8.3.2 Character height (Specific to Chinese, Korean and Japanese characters.)
Acceptance criterion: character height is greater than or equal to the
viewing distance divided by 143
Recommended viewing distance is between 457 mm (18 in.) and 762 mm
(30 in.).
Viewing distance 457-
762 mm

Section 9: Hand Control Location
Section Indicator Figure
9.0 Hand Control Location (These criteria only apply to controls, tools, and
materials accessed for routine production operation and maintenance.)
9.1 Standing station
NOTE: A standing station is one where the machine operator can
assume a standing posture or a seated posture in a tall stool,
which places the operator at approximately the same stature.
9.1.1 Vertical location of very infrequently used controls (controls used less
often than once every 24 hours) measured from the standing surface to the
centerline of the control.
Acceptance criteria: maximum 1640 mm (64.5 in.).
minimum 0 mm (0 in.).
Minimum 0 mm
(0 in.)
Maximum 1640
mm
(64.5 in.)
9.1.2 Location of infrequently used and/or critical controls. Maximum reaches
are indicated for various heights. Reaches are measured from the leading
edge of the equipment or obstacle.
Acceptance criteria: controls should not be located above 1638 mm (64.5
in.) or below 838 mm (33 in.).
NOTE A: Interpolate for intermediate values.
NOTE B: Reach distances should be measured from the leading edge of
the machine housing or obstructions between the machine
operator and the control. Obstructions include keyboard trays,
drip trays, machine anti-vibration pads and load-bearing pads.
NOTE C: See Figure 9.1.2 for maximum recommended reaches.

various heights. Reaches are measured from the leading edge of the
equipment or obstacle.
Acceptance criteria: controls should not be located above 1270 mm (50
in.) or below 940 mm (37 in.).
NOTE A: Interpolate for intermediate values.
NOTE B: Reach distances should be measured from the leading edge of
the machine housing or obstructions to the center of the
