This document specifies an additional test for verifying the stability of a laden truck whose utilization creates the special operating condition whereby the load centre of gravity is substantially offset from the truck's longitudinal centre plane or from the centred position by design.

A load is considered to be substantially offset if displaced by more than:

—    100 mm, for a truck with a rated capacity < 5 000 kg;

—    150 mm, for a truck with a rated capacity ≥ 5 000 kg and ≤ 10 000 kg;

—    250 mm, for a truck with a rated capacity > 10 000 kg and < 20 000 kg;

—    350 mm, for a truck with a rated capacity ≥ 20 000 kg.

This document is applicable to the following types of trucks as defined in ISO 5053-1:

a)    counterbalance trucks;

b)    reach and straddle trucks;

c)    pallet stackers;

d)    bidirectional and multidirectional trucks;

e)    industrial variable-reach trucks;

f)     rough-terrain trucks with mast;

g)    rough-terrain variable reach trucks;

h)    counterbalance trucks with articulated steering;

i)     variable-reach container handler;

j)     counterbalanced container handler;

k)    order-picking truck;

l)     slewing rough-terrain variable-reach truck.
