The tests are static in nature to minimize complexity and cost of required testing facilities. As far as practical, applied static loads should take into account the combined static and dynamic loads anticipated in service.
A five year review of ARP1840 resulted in major revisions to the original document. A definitions section was added and some renumbering of the paragraphs. Figures 2 and 3 were deleted from the document as these pallets are now included in NAS 3610/AS36100A.
Document was restructured to be more general in nature so as to read as an ARP versus an AS.
Metric measurements were added where they did not exist in previous version.
Figure 1 was maintained as an example of an STC Type pallet.
All remaining changes were either spelling or grammar.
