This SAE Standard specifies a stationary test method for determining the masking effect caused by parts of the base machine with equipment as specified by the manufacturer on a visibility test circle around the machine from the eye position point of a seated operator. It specifies a method for evaluating the maskings that may be present. It applies to earthmoving machines which have a specific operator’s station. It does not consider evaluation of maskings which may be present with operational movement of working tools.

This recommended practice is limited to enclosure configurations in which the operator sits or stands as illustrated in Figs. 1 and 2 during mobile machine operations.

General criteria are presented as guidelines for: control device location, resistance, and actuation of hand and foot controls by the machine’s operator. The criteria are based upon physical limitations as defined by human factors engineering principles.

This SAE Standard specifies a stationary test method for determining and documenting the masking effect caused by parts of the base machine with equipment as specified by the manufacturer within a visibility test circle around the eye position of a seated operator. It applies to earthmoving machinery which has a specific seated operator’s position.
