"Penetration Method" has been developed for the determination of the Flow Moisture Point of coal, which cannot be measured by the IMO Flow Table Test. On the basis of this method, new apparatus and criterion to judge the occurrence of liquefaction are introduced to establish a new method which can be applicable to mineral concentrates and similar materials. Test results show good agreements with those by the IMO Flow Table Method. It is concluded that the new method can be widely applicable with reasonable reliability. A test procedure which includes the new version of the Penetration Method is proposed to IMO for amending Appendix D of the BC Code.
