TML & FMP. Transportable Moisture Limit (TML) of Iron Ore Bulk cargo by Flow Table Test Method When solid bulk cargoes, such as Iron ores contain high moisture, they get subjected to cyclic forces due to rise in pore water flow pressure, it results in steep rise in loss of strength of material to be held in definite shape and there is loss of stability of the cargo causing the material to flow
