AS ISO 22915.16:2015 pdf download.Industrial trucks——Verification of stability Part 16: Pedestrian-propelled trucks.
1 Scope
This part of ISO 22915 specifies tests for verifying the stability of pedestrian-propelled trucks. It is applicable to straddle, pallet and platform stacker trucks with capacities not exceeding 1 000kg, with manual or battery-powered lift; scissors lift pallet trucks with lift heights up to 1 000 mm and rated capacity up to 1 000kg, with manual or battery-powered lift; platform trucks. It also applies to trucks operating under the same conditions when equipped with load-handling attachments. It is not applicable to trucks with retractable devices such as a mast or fork.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5053 and ISO 22951-1 apply.
4 Requirements
4.1 General See ISO 22915-1.
4.2 Position of the truck on the tilt table All tests shall be carried out with castors and swivelling wheels, when fitted, in the position of least stability (see Tables 1, 2 and ).
4.2.2 Tests 1, 2,4 and 7 to 10 for longitudinal direction of test The truck shall be positioned on the tilt table with the steer axle B—B and the load axle C—C parallel to the tilt axis X—Y of the tilt table.
4.2.3 Tests 3, 5, 6 and 7 to 10 for lateral direction of test The truck shall be positioned on the tilt table with the line M—N parallel to the tilt axis X—Y of the tilt table. Point M is defined as follows:
a) For trucks with one or more non-sprung castor wheels, point M is the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel axle and the midpoint of the wheel(s), with the non-sprung castor being positioned with the centreline of the castor wheel axle parallel to tilt axis X—Y or at any other orientation that produces minimum stability.
b) For trucks having non- articulating dual steer wheels, point M is the vertical projection onto the tilt table of the point of intersection between the centreline of the steer axle and the centreline of the width over both steer wheels, with the axle of the steer wheels positioned parallel to the tilt axis X—Y or at any other orientation that produces minimum stability.
c) For trucks with stabilizers, point M is the vertical projection onto the tilt table of the point of symmetry of the stabilizer contact surface. 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.
5 Verification of stability
5.1 Dynamic test — Platform trucks
This dynamic test applies only to platform trucks.The unladen truck moving at a stabilized speed of 1 rn/s ± 10 % shall be pushed into a vertical obstacle 20 mm high with its wheel or both wheels at the same time. The force to push the truck shall cease when the truck hits the obstacle. The force to move the platform shall be applied at the lower platform (see Figure 2). This test shall be carried out in both directions, i.e. pushed and pulled. The unladen truck shall not tip over after coming into contact with the obstacle.
5.2 Tilt table tests
The stability of a truck shall be verified according to Tables 1, 2 or 3, as applicable.AS ISO 22915.16 pdf download.
