4 Basic dimensions
4.1 Light spacing dimensions
The following three maximum light spacings for intended machine operations shall be used as specified in Table 1:
a) 65 mm, the light spacing that represents the binocular eye spacing of 50% of seated earth-moving machinery operators;
b) 205 mm, the maximum light spacing that represents the range of eye movement (considering body torso and head movement) of 50 % of earth-moving machine operators when looking to a 45° angle to the rear (135° clockwise or anti-clockwise from straight ahead position);
c) 405 mm, the maximum light spacing that represents the range of eye movement (considering body torso and head movement) of 50 % of earth-moving machine operators when looking to the front (90° clockwise and anti-clockwise from the straight ahead position).
4.2 Masking dimensions
The allowable masking dimensions are specified in Table 1.
4.3 Reference dimensions for measurement purposes
The following reference dimensions for measurement shall be used:
a) 1 m, the distance used in conjunction with the RB to describe the near field (closest distance) around earth-moving machinery;
b) 1,5 m, 1,2 m and 1,0 m, the maximum height above the ground reference plane on which a visibility observation in the near field is made according to Table 2.
NOTE 1,5 m, the maximum height above the ground reference plane on which a visibility observation in the near field is made, based on the height of a small earth-moving machinery operator (1,55 m as specified in Iso 3411).
c) 12 m, the radius of the VTC on a horizontal surface measured from the FPCP. NOTE The 1 m rectangular boundary in a) above has been modified in 8.3.3.1.
5 Test apparatus
5.1 Light source apparatus, capable of positioning a light bar horizontally with at least two halogen light bulbs (or equivalent) mounted with the bulbs vertically. Each light bulb should be horizontally movable on the light bar from 32,5 mm to 202,5 mm on each side of the light bar centre point. It shall be possible to rotate the light bar through 3600 about the FCCP. The vertical centre point of the light bulb filaments shall be located 680 mm above and 20 mm in front of the seat index point (SIP) as defined by ISO 5353 (see Figure 1).
5.2 Vertical test object, 1,0 m,1,2 m, or 1,5 m high, with a suitable width (e.g. 100 mm to 150 mm), used to evaluate the maskings on the RB. See Table 2 for the test object height to be used by machine type, mass, and region of the RB. The 1,5 m test object can also be used for possible mirror evaluation (see 7.3).
5.3 Test surface, an area of firm surface, e.g. compacted earth, concrete, paved surface, with a gradient of not more than 3 % in any direction.AS ISO 5006 pdf download.
