MSC 85/26/Add.2ANNEX 3Page 3301.1.2 Apparatus (see figure 1.1.2).1 Standard flow table and frame (ASTM Designation (C230-68) – see 3).Figure 1.1.2 – Flow table and accessory apparatus.2 Flow table mounting (ASTM Designation (C230-68) – see 3)..3 Mould (ASTM Designation (C230-68) – see 3)..4 Tamper (see figure 1.1.2.4): the required tamping pressure may be achieved byusing calibrated, spring-loaded tampers (examples are included in figure 1.1.2.4)or some other suitable design of tamper that allows a controlled pressure to beapplied via a 30 mm diameter tamper head..5 Scales and weights (ASTM Designation (C109-73) – see 3) and suitable samplecontainers..6 Glass graduated measuring cylinder and burette having capacities of 100-200 mland 10 ml, respectively..7 A hemispherical mixing bowl approximately 30 cm diameter, rubber gloves anddrying dishes or pans. Alternatively, an automatic mixer of similar capacity canbe used for the mixing operations. In this case, care should be exercised to ensurethat the use of such a mechanical mixer does not reduce the particle size orconsistency of the test material..8 A drying oven with controlled temperature up to approximately 110 o C. This ovenshould be without air circulation.I:\MSC\85\26-Add-2.doc

MSC 85/26/Add.2ANNEX 3Page 3311.1.3 Temperature and humidityFigure 1.1.2.4 – Examples of spring-loaded tampersIt is preferable to work in a room where the samples will be protected from excessivetemperatures, air currents and humidity variations. All phases of the material preparation andtesting procedure should be accomplished in a reasonable space of time to minimize moisturelosses and, in any event, within the day of commencement. Where possible, sample containersshould be covered with plastic film or other suitable cover.1.1.4 ProcedureThe quantity of material required for a flow moisture test will vary according to the specificgravity of the material to be tested. It will range from approximately 2 kg for coal to 3 kg formineral concentrates. It should be collected as a representative sample of the cargo beingshipped. Experience has shown that more accurate test results will be obtained by ensuring thatthe moisture content of the test sample is increased rather than decreased towards the FMP.I:\MSC\85\26-Add-2.doc
