This part of ISO22915 specifies the tests for verifying the stability of counterbalanced trucks with masts when handling empty or laden freight containers of 6m (20 ft) length and longer.
It is applicable to these types of industrial trucks that are equipped with forks, a spreader, (top lift and side lift), or other load handling means applicable for container handling.
This International Standard does not apply to trucks when handling a container which has a mobile centre of gravity (see ISO3874).
