The ISO 22915 series deals with the safety of industrial trucks, as defined in ISO 5053-1, relative to their stability and the verification of that stability.

This document specifies basic test criteria and requirements for verifying the stability of industrial trucks, hereafter referred to as "trucks".

It is applicable 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 trucks with mast as specified in ISO 22915-13;

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

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

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

o)？towing tractors, burden and personnel carriers as specified in ISO 22915-17;

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

q)？order-picking trucks with operator position elevating above 1？200？mm as specified in ISO？22915-21;

r)？lateral- and front-stacking trucks with and without elevating operator position as specified in ISO？22915-22;

s)？slewing variable-reach rough-terrain trucks as specified in ISO 22915-24.

It is also applicable to trucks operating under the same conditions when equipped with load-handling attachments and low-lift trucks with lift height up to and including 500？mm.

This document does not apply to the following:

—？trucks handling suspended loads which can swing freely.
