ISO 22915-1:2016 series deals with the safety of industrial trucks, as defined in ISO 5053-1, relative to their stability and the verification of that stability. For the purposes of ISO 22915, industrial trucks are wheeled, self-propelled, or pedestrian-propelled vehicles excepting those running on rails. They are either operator-controlled or driverless, and are designed to carry, tow, push, lift, stack or tier in racks.

ISO 22915-1:2016 specifies basic test criteria and requirements for verifying the stability of industrial trucks, hereafter referred to as trucks.

It applies to the following truck types and special conditions:

a) counterbalanced trucks with mast as specified in ISO 22915-2;

b) reach and straddle trucks as specified in ISO 22915-3;

c) pallet stackers, double stackers, and order-picking trucks with operator position elevating up to and including 1 200 mm lift height as specified in ISO 22915-4;

d) single-side-loading trucks as specified in ISO 22915-5;

e) bidirectional and multidirectional trucks as specified in ISO 22915-7;

f) additional stability test for trucks operating in special conditions of stacking with the mast tilted forward as specified in ISO 22915-8;

g) counterbalanced trucks with mast handling freight containers of 6 m (20 ft) length and longer as specified in ISO 22915-9;

h) additional stability test for trucks operating in special conditions with the load substantially laterally displaced by powered devices as specified in ISO 22915-10;

i) industrial variable-reach trucks as specified in ISO 22915-11;

j) industrial variable-reach trucks handling freight containers of 6 m (20 ft) length and longer as specified in ISO 22915-12;

k) rough-terrain variable-reach trucks as specified in ISO 22915-14;

l) counterbalanced trucks with articulated steering as specified in ISO 22915-15;

m) pedestrian-propelled trucks as specified in ISO 22915-16;

n) additional stability test for trucks operating in the special condition of offset load, offset determined by utilization as specified in ISO 22915-20;

o) order-picking trucks with operator position elevating above 1 200 mm as specified in ISO 22915-21.

It also applies to trucks operating under the same conditions when equipped with load-handling attachments.

ISO 22915-1:2016 does not apply to the following:

- trucks handling suspended loads which may swing freely;

- low-lift trucks with lift height up to and including 500 mm.
