32、en in EN 58:2012 and the following apply. 3.1 laboratory sample sample of bituminous binder intended for laboratory tests Note 1 to entry: It may be a spot sample, a composite sample or a part thereof (a divided sample). 3.2 test sample sample of bituminous binder produced by treatment or subdivisio

33、n of a laboratory sample for individual testing 4 Principle In order to produce the laboratory sample, the test material shall have been sampled in accordance with EN 58. Perceptible properties of the test material shall be checked in accordance with EN 1425, prior to performing this European Standa

34、rd. Homogenize the laboratory sample before the test samples are taken. For certain tests (7.3.2), transfer the laboratory sample directly to the test sample containers, and for other tests (7.3.3), sieve the laboratory sample prior to testing. Store the laboratory sample from which the test samples

35、 are taken under controlled conditions. Stir gently to render it uniform and warm the sample, if necessary. Prepare all test samples that are required for one property at the same time. 5 Reagents and materials Use only reagents of standard analytical grade and water conforming to grade 3 of EN ISO

36、3696:1995. 5.1 Solution SaAqueous solution with a nominal 0,01 mol/l of sodium hydroxide (NaOH) containing a nominal 1 % mass fraction sodium oleate. This solution may be used for preparing anionic emulsion samples. The actual soap solution may be used if available on site, in case of routine tests

37、or for simplicity. NOTE Sastands for “anionic solution” as this solution is used for preparing anionic emulsion samples. DIN EN 12594:2015-01 EN 12594:2014 (E) 6 5.2 Solution ScAqueous solution of nominal 0,01 mol/l of hydrochloric acid (HCl) containing a nominal 1 % mass fraction cetyltrimethylammo

38、nium bromide. This solution may be used for preparing cationic emulsion samples. The actual aqueous phase may be used if available on site, in case of routine tests or for simplicity. NOTE SCstands for “cationic solution” as this solution is used for preparing cationic emulsion samples. 5.3 Efficien

39、t rinsing agent, suitable solvent rinsing agents shall be used. 5.4 Ethanol, 99 % volume fraction minimum or 95 % volume fraction, denatured. 6 Apparatus Usual laboratory apparatus and glassware, together with the following: 6.1 Ventilated oven or ventilated laboratory oven with a temperature accura

40、cy of 5 C, checked at midpoint and working space at suitable intervals. 6.2 Indirect heating apparatus, e.g. oil bath with thermometer or equivalent. 6.3 Melting pan of appropriate material. 6.4 Any appropriate stirrer, e.g. manual (such as spatula) or mechanical equipped with a propeller. 6.5 Metal

41、 sieve, mesh size 0,500 mm, made from brass or stainless steel if used with bitumen emulsions. 6.6 Aluminium foil or lid for melting pan. 6.7 Test sample container or moulds of appropriate material with a lid or other closure, or glass conical flask with a ground glass stopper. 7 Procedure for sampl

42、e preparation 7.1 Solid or semi-solid samples 7.1.1 Samples up to one litre Ease the lid or other closure of the sample container and place the container with the lid loose in the oven for a maximum of 120 min at not more than 100 C above the expected softening point as defined in EN 1427. For modif

43、ied bitumen, use the procedure provided by the supplier. If no guidance is provided for polymer modified bitumen according to EN 14023, the temperature of the oven shall be within 180 C to 200 C, irrespective from the softening point. If 120 min are not sufficient to melt the polymer modified bitume

44、n sample completely, place the sample container into a heating jacket and continue the heating of the sample under continuous stirring. In any case, 200 C shall not be exceeded. Remove the container from the oven and stir (6.4) the melted sample with care in order to avoid incorporating air bubbles

45、into the sample. For modified binders, stir according to handling suggestion from supplier, when available. Allow any air bubbles to escape, if necessary by placing the sample in the oven for not more than 5 min. Pour the liquefied and homogenized sample into the moulds or test sample containers. Ca

46、rry out the entire procedure (melting, homogenizing and moulding) within 135 min. DIN EN 12594:2015-01 EN 12594:2014 (E) 7 If the sample contains coke/detritus, it is allowed to sieve the sample through a warm sieve (6.5) before collecting the test sample. The coke/detritus and sieving shall be ment

47、ioned in the test report under g) and h) (see Clause 8). Discard the residue sample that has been heated. 7.1.2 Samples greater than one litre If division of a sub-sample is necessary, ensure that the sub-sample is representative of the bulk sample. If necessary, take a sufficient amount of material

48、 (100 g minimum) from the container by using an appropriate tool (e.g. a warmed but not glowing knife) and transfer the material into the melting pan. This procedure is not valid for polymer modified bitumen according to EN 14023 which needs to be melted and homogenized following the procedure descr

49、ibed below before a sub-sample can be taken. Place the melting pan in the appropriate heating device (6.1 or 6.2). Melt the material by stirring (6.4) at a maximum temperature not more than 100 C above the expected softening point as defined in EN 1427. For modified bitumen, follow the procedure provided by the supplier. If no other guidance is provided by the supplier for polymer modified bitumen according to EN 14023, the temperature of the oven shall be within 180 C to 200 C, irre
