If the manufacturer shows other possible ratings on the capacity plate (see Clause 6), tests shall be carried out with maximum load at the corresponding height as well as with the load corresponding to the maximum height as agreed between the interested parties.
4.4 Tests for trucks with attachments
Trucks with attachments shall be subjected to the foregoing stability tests, as appropriate.
The test loads and their positioning shall be those specified on the capacity plate(s) of the truck equipped with the attachment when used under the special operating condition and in accordance with the manufacturer’s instructions.
The lift heights required in the tests shall be measured between the surface of the tilt table and the underside of the load in its approved handling position or the underside of the load handling means, whichever is the smaller.
