8.4.1 A ship's master may carry out a check test
for approximately determining the possibility of flow on board ship
or at the dockside by the following auxiliary method:
-
Half fill a cylindrical can or similar container (0.5 to 1 L
capacity) with a sample of the material. Take the can in one hand and bring it
down sharply to strike a hard surface such as a solid table from a height of about
0.2 m. Repeat the procedure 25 times at one- or two-second intervals. Examine the
surface for free moisture or fluid conditions. If free moisture or a fluid
condition appears, arrangements should be made to have additional laboratory tests
conducted on the material before it is accepted for loading.
8.4.2 If samples remain dry following a can test, the
moisture content of the material may still exceed the transportable moisture limit
(TML).
