Transportable Moisture Limit (TML) & Flow Moisture Point (FMP)
The issuance of FMP/TML certificates is one of the most important tests that ALS can perform, providing confidence to clients that their material is safe to transport via bulk carrier.
The Flow Moisture Point (FMP) is the point at which a granular bulk material becomes fluid. A Flow Table Test (FTT) is conducted to find the FMP, with the TML calculated to be 90% of this figure. This is the maximum moisture level at which it is safe to ship the material; if the cargo is found to have a higher moisture content than the TML, it is strongly recommended that the cargo not be transported (unless the vessel is specially built for this).
