This International Standard specifies a flow-table method for the determination of the transportable moisture
limit (TML) of copper, lead and zinc sulfide concentrates, which may liquefy during transport.
This International Standard is applicable to the determination of the TML of concentrates containing 10 % to
80 % (mass fraction) of lead, or 10 % to 65 % (mass fraction) of zinc, or 10 % to 55 % (mass fraction) of
copper. It is applicable to TMLs in the range 3 % to 28 % (mass fraction).
