MSC 85/26/Add.2ANNEX 3Page 329APPENDIX 2LABORATORY TEST PROCEDURES, ASSOCIATED APPARATUSAND STANDARDS1 Test procedures for materials which may liquefy and associated apparatusThree methods of testing for the transportable moisture limit are currently in general use:.1 flow table test;.2 penetration test;.3 Proctor/Fagerberg test.As each method has its advantages, the selection of the test method should be determined bylocal practices or by the appropriate authorities.1.1 Flow table test procedure1.1.1 ScopeThe flow table is generally suitable for mineral concentrates or other fine material with amaximum grain size of 1 mm. It may also be applicable to materials with a maximum grain sizeup to 7 mm. It will not be suitable for materials coarser than this and may also not givesatisfactory results for some materials with high clay content. If the flow table test is not suitablefor the material in question, the procedures to be adopted should be those approved by theauthority of the port State.The test described below provides for determination of:.1 the moisture content of a sample of cargo, hereinafter referred to as the testmaterial;.2 the flow moisture point (FMP) of the test material under impact or cyclic forces ofthe flow table apparatus; and.3 the transportable moisture limit of the test material.I:\MSC\85\26-Add-2.doc
