WARNING - Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

NOTE 1 Applying the release agent coating is easier when the plate is warmed to approximately 40 °C. NOTE2 Instead of a release agent, other materials, e.g. baking paper, can be used. 6 Apparatus 6.1 Ring and Ball apparatus,
NOTE Either manual, semi-automatic or automatic, comprising the elements given in 6.1.1 to 6.1.9. 6.1.1 Rings, two, square-shouldered, in brass and conforming to the dimensions shown in Figure 1. 6.1.2 Pouring plate, flat, smooth, metal, approximately 50 mm × 75 mm and 1,5 mm to 2,0 mm thick with the edges turned down (see Figure 2) or a ceramic tile 5 mm to 6 mm thick. 6.1.3 Balls, stainless steel, two, (9,50 ± 0,05) mm in diameter, each having a mass of (3,50 ± 0,05) g. 6.1.4 Ball centering guides, brass, two for centring the steel balls, one for each ring. An example of ball centring guide is given in Figure 3. 6.1.5 Ring holder and assembly, stainless steel or brass, with a holder (A) to support the two rings in a horizontal position, conforming to the shape and dimensions shown in Figure 4, supported in the assembly shown in Figure 5. The bottom of the shouldered rings in the ring holder shall be (25,0 ± 0,4) mm above the upper surface of the bottom plate (B) (see Figure 6); the upper edge of the rings shall be (50 ± 3) mm below the surface of the bath liquid. 6.1.6 Bath, glass beaker capable of being heated, with not less than an 85 mm inside diameter and not less than a 120 mm depth from the bottom of the beaker, as shown in Figure 5. NOTE A squat form 600 ml beaker is suitable.

The rotation speed of the stirring bar shall be approximately 100 r/min. NOTE The stirrer blade of the propeller stirrer should preferably be placed at a level between the bottom plate of the the assembly and the bottom of the beaker (see Figure 5). WARNING — If the propeller stirrer is electrically driven, ensure that it is safely earthed. 6.1.9 Semi-automatic or automatic equipment Instead of the apparatus described in 6.1.1 to 6.1.8, a semi-automatic or automatic apparatus may be used (after it has been calibrated). The results obtained shall be the same as with the manual method and shall be within the precision of the manual method. If automatic equipment is used, it shall be calibrated as frequently as necessary, but at least once a year. In case of doubt, the referee method shall be the manual one with the apparatus as shown in Figure 5. NOTE When using an automatic apparatus, it is possible for the ball to trigger the interruption of a ray of light at a distance of (25,0 ± 0,4) mm below the underside of the ring, rather than the ball touching the bottom plate. 7 Preparation and preservation of laboratory samples and test samples Take the laboratory sample in accordance with EN 58 taking all necessary safety precautions and ensuring that the test sample is representative of the laboratory sample from which it is taken. Prepare the test sample in accordance with EN 12594. For modified bitumen the quantity of sample shall be adjusted to fill four rings in case the test has to be repeated (see 8.6, a)). Heat the two brass rings but not the pouring plate, to approximately 90 °C above the expected softening point and place them on the pouring plate treated with the release agent (see NOTE 1 in 5.3). Do not use too much of the release agent to avoid particles in the bath liquid that can interfere with the ray of light if used. Pour a slight excess of the heated bituminous binder into each of the rings, then allow the specimens to cool in ambient air for at least 30 min. For materials that are soft at room temperature, cool the test sample for at least 30 min at an air temperature at least 10 °C below the expected softening point. No more than 4 h shall elapse until completion of the test from the time the test samples are poured.
