3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISo 5053 and ISO 22915-1 apply.
4 Test conditions
4.1 General See ISO 22915-1.
4.2  Position of truck on tilt table
4.2.1 Load and steer axles
The load and steer axles are defined by Figure 1.
4.2.2 Tests I and 2
The truck shall be positioned on the tilt table so that its load axle, C—C. is parallel to the tilt axis, X—Y, of the tilt
table. See Table 1.
4.2.3 Tests 3 and 4
The truck shall be positioned on the tilt table in a turning position with the line, M—N. parallel to the tilt axis, X—Y, of the tilt table.
As shown in Table 1, the steered wheel nearest to the tilt axis shall be parallel to X—Y. Point M is defined as follows.
a) For trucks having an articulating steer axle: point M shall be the projection on the tilt table of the intersection of the longitudinal centre-plane, A—A, of the truck with the axis of this axle.
b) For trucks steered by a single wheel: point M shall be the centre point of the tread contact area between the steered wheel and the tilt table surface.
c) For trucks steered by twin wheels: point M shall be the centre point of the tread contact area between the steered wheel closest to the tilt axis, X—Y. of the tilt table and the tilt-table surface.
d) For trucks having wheels for steenng not connected by a common axle, but that are arranged to articulate approximately about the longitudinal centre-plane of the truck: point M shall be the projection on the tilt table of the intersection of the longitudinal centre-plane of the truck, A—A, with the steer axle B—B connecting the vertical turning axis of the steer wheels.
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.AS ISO 22915.2 pdf free download.
