AS ISO 6682 pdf download.Earth-moving machinery — Zones of comfort and reach for controls
1  Scope
This International Standard defines zones of comfort and reach for controls derived from the overlapping reach capability of large and small operators in the seated position.
2  Field of application
This document is intended as a guide for the design of the operator compartment controls for earth- moving machinery.

4  Definitions
4.1 SIP Seat Index Point as defined by ISO 5353 (fixed at nominal seat adjustments). 4.2 control displacement Travel or movement of a control through its operational range. 4.3 control location Positions of a control, including the corresponding control displacement, defined from the SIP. 4.4 primary controls Controls that are used frequently or continuously by the operator, such as: a) Machine controls: transmission, brakes, steering, engine speed, etc. b) Working tool controls: blade controls, bucket controls, ripper controls, etc. 4.5 secondary controls Controls that are infrequently used by the operator, such as lights, windscreen wipers, starter, heater, air conditioner, etc. 4.6 zones of comfort Preferred control location zones for primary hand and foot controls. Both large and small operators should be able to reach controls comfortably in these zones.4.7 zones of reach Control location zones for secondary hand and foot controls. Both large and small operators should be able to reach controls in these zones from the seated position, but the operator may be required to rotate or lean forward and to each side. 4.8 XYZ coordinate system Coordinate system used to define the control zone locations: a) Origin at the SIP. b) X-axis; fore-aft, positive to front of the SIP. c) y-axis; lateral, positive to right of the SIP. d) Z-axis; vertical, positive upward from the SIP. [SOURCE: See ISO 6746/1.] 4.9 flexion Movement that changes the angle between body parts. 4.10 adduction Movement in a plane normal to the plane of flexion and directed towards or past the mid-axis (XZ plane) of the body. 4.11 abduction Movement in a plane normal to the plane of flexion and directed away from the mid-axis (XZ plane) of the body. 4.12 circumduction Movement about an axis that circumscribes a cone.
5  Control location zones
5.1 The control location zones are determined in relation to the SIP. 5.2 The zones of comfort and zones of reach for hand and foot controls are shown in figures 1, 2 and 3. These zones correspond to the human physical dimensions given in ISO 3411. 5.3 Control location zones are defined by the common reach zones for large and small operators. The specific conditions which are used to derive these control location zones are presented in annex A. 5.4 The zone of comfort for hand controls may be rotated up to 30° about a vertical axis through the SIP for reaching rear equipment controls that are used whilst the operator is turned in the seat. 5.5 The zones of comfort and reach for hand controls may be increased by 75 mm for controls operated by finger grasp. 5.6 Annex B lists the X, Y and Z coordinates and radii of figures 1, 2 and 3 which should be used when developing larger scale drawings as drafting aids.
A.1.1 The seat back cushion has a 10° nominal rake angle and a width of 500 mm. The control location zones may be affected if the nominal seat back cushion rake angle exceeds ± 5° variation from 10° or if the seat back cushion width exceeds 550 mm. A.1.2 Both large and small operators position the seat at the nominal vertical adjustment. Vertical seat adjustment (75 mm recommended) is used by individual operators to account for anthropometric variations: long legs but short arms, long trunk but short legs, etc. A.1.3 The seat has a 150 mm fore-aft adjustment. The small operator adjusts the seat to the most forward position and the large operator adjusts the seat to the most rearward position. A.1.4 Control location zones for machines that have between 100 mm and 150 mm fore-aft seat adjustment can be derived as follows: a) use hand control location zones defined in figures 1, 2 and 3; b) modify foot control location zones defined in figures 1, 2 and 3 by narrowing the foot control location zones by 25 mm in both the fore and aft directions.
