DIN EN 12592:2015-01 EN 12592:2014 (E) 4 1 Scope This European Standard specifies a method for determining the degree of solubility of bituminous binders having little or no mineral matter other than recovered bituminous binders from asphalt m
20、ixes, in a specific solvent. Toluene is used as the solvent for reference tests. NOTE Bituminous binders will have varying solubility in different solvents. WARNING Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to add
21、ress all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to identify the hazards and assess the risks involved in performing this test method and to implement sufficient control measures to protect individual operators (and the environme
22、nt). This includes appropriate safety and health practices and determination of the applicability of regulatory limitations prior to use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

25、he purposes of this document, the following term and definition apply. 3.1 solubility portion of material that is soluble in a specific solvent 4 Principle A sample of bituminous binder is dissolved in a solvent. The solution is filtered through a layer of powdered glass in a sintered crucible. The
26、insoluble material is then washed, dried, and weighed. 5 Reagents and materials Examples of specific solvents are given in 5.1 and 5.2. 5.1 Toluene, conforming to ISO 5272. DIN EN 12592:2015-01 EN 12592:2014 (E) 5 5.2 Xylene, conforming to ISO 5280. 6 Apparatus Usual laboratory apparatus and glasswa
27、re, together with the following: 6.1 Filtering apparatus NOTE Assembled as illustrated in Figure 1. Details of the component parts are as given in 6.1.1 to 6.1.5. 6.1.1 Sintered glass crucible, porosity P4 (see ISO 4793), effective diameter approximately 30 mm. 6.1.2 Powdered glass, borosilicate gla
28、ss powder, particle diameter approximately between 50 m and 80 m. The powdered glass functions as filter aid. The granulometry of powdered glass may evolve over time. It is recommended to check the granulometry prior to using the powdered glass, if used. Instead of powdered glass, glass fibre or Wha
29、tman filter grade 934 or equivalent may also be used. However, the use of powdered glass is the reference method. When using glass wool or filter as filter aid, a Gooch crucible may also be used. 6.1.3 Filter flask, 250 ml or 500 ml, heavy-wall, with a side tube. 6.1.4 Filter tube, 40 mm to 42 mm in
30、side diameter. 6.1.5 Rubber tubing or adaptor, for holding the crucible on the filter tube. Other suitable assemblies permitting vacuum filtration with a crucible can be used. 6.2 Oven, capable of maintaining a temperature, T, of 15 C to 25 C above the boiling temperature of the selected solvent. 6.
31、3 Balance, accurate to 0,2 mg and readable to 0,1 mg. 7 Sampling Take the test 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. Ensure that the laboratory sample is homogenous
32、 and not contaminated (see EN 1425). If the sample contains water, heat a representative portion of between 100 g and 200 g at a temperature not exceeding 130 C stirring constantly until the binder ceases to foam. 8 Procedure 8.1 Test conditions Normally the temperature at which the test is run is n
33、ot critical and may be performed at the laboratory air temperature. For reference tests, the flask with the sample in solution shall be placed in a water bath maintained at (25 2) C for 1 h before filtering. Crystallized paraffins may disturb the analysis of the samples with high wax content. To avo
34、id this, use the higher test temperature of 40 C. DIN EN 12592:2015-01 EN 12592:2014 (E) 6 8.2 Preparation of crucible Weigh (3,0 0,1) g of clean dried powdered glass into the crucible. Place the crucible in the filter tube (6.1.4). Wash the powdered glass (6.1.2) with a small portion of the selecte
35、d solvent (see Clause 5) and filter carefully into the flask with or without vacuum, as necessary. Repeat the washing process several times. Place the crucible on a heater or steam bath for 30 min before placing in the oven (6.2) at the temperature T (see 6.2) for at least 20 min. Remove the crucibl
36、e from the filter tube and cool in a desiccator for 25 min to 35 min and determine the mass to the nearest 0,1 mg. Repeat the drying and weighing until constant mass is obtained, i.e. the difference between the two weights shall not exceed 0,5 mg. 8.3 Test method Prepare the test sample according to
37、 EN 12594 in order to homogenize it and transfer (2 1) g of the dry sample, if necessary, using a warmed knife, into a suitable weighed container, e.g. Erlenmeyer flask. Determine the mass of the container and sample to the nearest 1 mg. Add 100 ml of the selected solvent to the container in small p
38、ortions with continuous agitation until all lumps disappear and no undissolved sample adheres to the container. For reference testing stopper or cover the container and set aside for at least 15 min (see 8.1). Place the previously prepared and weighed crucible in the filter tube (6.1.4). Wet the pow
39、dered glass with a small portion of solvent and filter the solution carefully into the flask through the powdered glass of the crucible with or without vacuum as necessary. If the insoluble matter is appreciable, retain as much of it as possible in the container until the solution has drained throug
40、h the filter aid. Wash the container with a small amount of solvent and, using a stream of solvent from a wash bottle, transfer all insoluble matter to the crucible. If necessary use a glass rod to remove any insoluble matter adhering to the container and transfer it into the crucible. Thoroughly ri
41、nse the glass rod and container and transfer it with the crucible. Wash the insoluble matter in the crucible with solvent until the filtrate flows substantially colourless, then apply strong vacuum to remove the remaining solvent or place the crucible into a vacuum desiccator. Remove the crucible fr
42、om the tube or desiccator, wash the bottom free of any dissolved matter, and place the crucible on a heater or a steam bath for 30 min. Place in an oven at the temperature T (see 6.2) for at least 20 min. Remove the crucible from the filter tube and cool in a desiccator for 25 min to 35 min and dete
43、rmine the mass to the nearest 0,1 mg. Repeat the drying and weighing until constant mass is obtained, i.e. the difference between the two weights is not more than 0,5 mg. Repeat the determinations, making at least two valid determinations. Two solubility determinations shall be considered valid if t
44、hey do not differ by more than 0,2 % mass. 9 Calculation Calculate either the total mass percentage of insoluble matter (xi) or the mass percentage of soluble matter (xs), of the sample in the solvent as follows: 100BAi=mmx (1) = 100100BAsmmx (2) where xiis the percentage of insoluble matter, in per
45、cent; DIN EN 12592:2015-01 EN 12592:2014 (E) 7 xsis the percentage of soluble matter, in percent; mAis the mass of insoluble material, in grams; mBis the mass of the dry sample, in grams. 10 Expression of results Express the solubility as the percentage of mass of soluble material xs, to the nearest
46、 0,05 %, as the mean of the two valid determinations. 11 Precision 11.1 Repeatability The difference between two test results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operat
47、ion of the test method, exceed 0,10 % absolute in only one case in twenty. 11.2 Reproducibility The difference between two single and independent results obtained by different operators working in different laboratories on identical test material would, in the long run, in the normal and correct ope
48、ration of the test method, exceed 0,15 % absolute in only one case in twenty. These precision data are not automatically applicable to modified bitumen, and for modified bitumen, they should only be used for guidance until criteria data are available. 12 Test report The test report shall contain at
49、least the following information: a) type and complete identification of the sample under test; b) reference to this European Standard; c) solvent used; d) results obtained (see Clause 10); e) any deviation, by agreement or otherwise, from the procedure specified; f) date of the test; g) type of filtrating medium (glass powder, glass fibre, filter) used.
