BS ISO 22915-7:2016 pdf download.Industrial trucks — Verification of stability — Part 7: Bidirectional and multidirectional trucks
1 Scope
This part of ISO 22915 specifies the tests for verifying the stability of bidirectional and multidirectional trucks with tilting or non-tilting mast or fork arms.
It is also applicable to trucks operating under the same conditions when equipped with load-handling attachments.
2 Normative references

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5053-1 and ISO 22915-1 apply.
4 Test conditions
4.1 General
The test conditions shall be in accordance with ISO 22915-1.
4.2 Position of the truck on the tilt table
4.2.1 Load/steer axle and drive/steer axle
The load/steer axle and drive/steer axle are defined by Figure 1.
4.2.2 Tests 1 to 5
The truck shall be positioned on the tilt table so that its drive/steer axle, B–B, and outrigger (load/steer) axle, C–C, are parallel to the tilt axis, X–Y, of the tilt table. See Table 1.
4.2.3 Tests 6 to 9
The truck shall be positioned on the tilt table with the line, M–N, or the outrigger (load/steer) axle, C–C,parallel to the tilt axis, X–Y, of the tilt table. See Table 1.
Point M is defined as follows.
a) For trucks with a sprung castor wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel width.
b) For trucks with drive/steer wheels in an articulated frame: point M shall be the vertical projection onto the tilt table of the point of intersection between the articulated frame axle and the lateral axis of the articulated frame.
c) For trucks with a single drive/steer wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel width.
As shown in Table 1, point N is defined as the centre point of the area of contact between the tilt table surface and the load wheel nearest to the tilt axis, X–Y, of the tilt table.
4.3 Datum point positions
4.3.1 General
Test 1 may be conducted with the horizontal position of the load datum point, E, unchanged when elevated from its lowered position as shown in Figure 2.
