5 Materials

5.1 Water, boiled and cooled before use

5.2 Reagents

6 Apparatus

6.1 All apparatus, unless otherwise stated, shall conform to the general requirements of EN 932-5.

6.2 Tube, made of transparent material with a height of not less than 200 mm and a diameter as specified in Table 1.

6.3 Vessel, made of transparent material. The internal bottom area of the vessel shall be large enough to have a minimum distance of 50 mm between the edge of the vessel and the wall of the tube. The vessel is fitted with a needle made of non-corrosive material, to indicate a water level (10 ± 1) mm above the base of the vessel, as shown in Figure 1.

6.4 Moisture container and close fitting lid, made preferably of transparent material, with an internal bottom area as specified in Table 1 and an internal depth of at least 60 mm. The container is fitted with a heat insulated cover or placed inside the test cabinet (see 6.13).

6.5 Glass basin, flat bottom crystallising type of 150 ml nominal capacity, to contain the potassium sulfate solution (see 5.2).

6.6 Balance, with an accuracy of 0,1 g for masses of 100 g or more and an accuracy of 0,01 g for masses of less than 100 g.

6.7 Plastic bag and rubber band, size appropriate to the diameter of the tube.

6.8 Wood stick (wooden dowel), with a diameter of approximately 0,25 X the diameter of the tube and a height of approximately 500 mm, for packing of the material in the tube.

6.9 Plastic water bottle with spout, for water supply and level adjustment.

6.10 Ventilated oven, thermostatically controlled to maintain a temperature of (110 ± 5) °C.

6.11 Steel straight edge, for levelling the surface of the aggregate with the top of the tube.

6.12 Adhesive tape, to seal the moisture container.

6.13 Test cabinet, or similar controlled environment capable of maintaining a stable temperature (± 2,0 °C) between 20,0 °C and 25,0 °C.
