DIN EN 13301:2010-06 EN 13301:2010 (E) 4 1 Scope This European Stand
20、ard specifies a method for the determination of the staining tendency of bitumen. This method is applicable to bitumen having a Ring-and-Ball softening point greater than or equal to 80 C. For softer bitumen, the test conditions may be modified by agreement between the involved parties. The procedur
21、e described in this document may be used to compare results against a material for which the staining tendency is known. NOTE Staining properties are related to the colloidal stability of the bitumen with higher values indicating lower stability. WARNING The use of this standard can involve hazardou
22、s materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations
23、 prior to use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitu

25、 definitions apply. 3.1 staining tendency tendency of oil components to separate spontaneously from bitumen NOTE The separation of oil components can cause staining in bitumen roofing products and others bituminous products with eventual damage of adjacent materials in storage and use. 4 Principle A
26、 retaining ring, filled with molten bitumen on a sheet of filter paper and supported on a flat horizontal plate is heated in an oven at a specified temperature for a specified time. The width of the resulting stained circle around the bitumen is calculated to determine the staining tendency of the b
27、itumen. The staining tendency has the dimension of length and results are rounded to nearest 0,5 mm. 5 Apparatus 5.1 Rings, square-shouldered as specified in EN 1427 (see Figure 1). The precision of the method depends upon accurate measurement of the diameter and precise alignment of the face and ri
28、m of the ring on a flat surface and it is essential that deformed rings shall not be used. DIN EN 13301:2010-06 EN 13301:2010 (E) 5 Dimensions in millimetres Key 1 Bitumen 2 Ring according to EN 1427 3 Filter paper 4 Inner diameter of ring 5 Diameter of stained circle Figure 1 Ring 5.2 Baking paper,
29、 silicone treated paper to be used when casting discs of bitumen in the rings. 5.3 Release agent, mixture of glycerol and dextrin or mineral talc, or other commercially available release agent. To prevent adhesion of bituminous binder to the pouring plate when casting discs, the surface of the metal
30、 pouring plate shall be thinly coated just before use with the release agent. NOTE Applying the release agent coating is easier when the plate is warmed to approximately 40 C. 5.4 Filter paper, standard cellulose fibre ashless analytical grade. The filter paper shall be of sufficient area to accommo
31、date the number of samples under test. A filter paper having a porosity of approximately 8 m with a thickness of approximately 210 m or a basis mass of approximately 92 g/m2has been found to be suitable. 5.5 Support plate, a flat, clean, smooth metal plate approximately 1,5 mm thick and with an area
32、 at least sufficient to support the size of filter paper used. 5.6 Oven, constant temperature, capable of maintaining a sample temperature of (80 1) C. 5.7 Thermometer, with a reading accuracy of 0,1 C in the required temperature range. 5.8 Measuring rule or device, with a reading accuracy of 0,5 mm
33、 or better. DIN EN 13301:2010-06 EN 13301:2010 (E) 6 6 Sampling The material under test shall be sampled in accordance with EN 58 and prepared in accordance with EN 12594. 7 Procedure 7.1 Sample preparation The bulk binder sample shall be placed in an oven maintained at a temperature of about 80 C a
34、bove the expected ring and ball softening point temperature or at a maximum of 200 C whichever is the lower. The container shall be filled to at least 50 % of its volume and shall be covered with a loose lid to protect it against oxidation. The total heating time shall be within 1 h 15 min to 1 h 45
35、 min for samples of 100 ml to 500 ml and 1 h 45 min to 2 h 15 min for samples of 500 ml to 1 000 ml. 7.2 Filling of the rings Place preheated rings on the baking paper no closer than 40 mm from each other (preheated to a maximum of 90 C above the softening point). Ensure that the lower face and rim
36、of the ring diameter is clean and that the bitumen disc will completely fill the ring and is flush with the lower face. Ensure that there are no traces of any release agent on the support plate or the ring. Pour the bitumen sample into a preheated ring, using 2 rings per sample, placed on the baking
37、 paper on the support plate. Allow to cool to ambient temperature and trim off the excess bitumen from the top of the ring as described in EN 1427. Place the filled rings on the filter paper, placed on the support plate, no closer than 40 mm from the edge of the paper or from another ring. NOTE When
38、 the sample is highly viscous, it may be difficult to pour into the rings. If excess bitumen has flown over the ring edge to the filter paper, it may stain the paper before the actual test. Continue to 7.4. 7.3 Filling of the rings (alternative procedure to 7.2) Place rings no closer than 40 mm from
39、 the edge of the filter paper or from another ring, ensuring that the lower face and rim of the ring diameter is clean and that the bitumen disc will completely fill the ring and is flush with the lower face. Ensure that there are no traces of any release agent on the support plate or the ring. Pour
40、 the bitumen sample into a preheated ring (preheated to a maximum of 90 C above softening point) using 2 rings per sample, placed on the filter paper on the support plate. Allow to cool to ambient temperature, and trim off the excess bitumen from the top of the ring as described in EN 1427. 7.4 Oven
41、 conditioning and measurement Identify each bitumen sample by appropriately marking the filter paper in pencil near its ring. DIN EN 13301:2010-06 EN 13301:2010 (E) 7 Place the entire assembly in the oven, preheated and stabilised at (80 1) C and allow remaining at this temperature for (120 1) h. Th
42、e assembly shall be placed on a shelf inside the oven; it shall not be placed on the bottom of the oven. Remove the assembly on the support plate from the oven and allow cooling to room temperature. For each ring, make measurements on the underside of the filter paper of the diameter of the stained
43、circle to the nearest 0,5 mm. Make four measurements approximately 45 apart. 8 Calculation Calculate the arithmetic mean of the four measurements for each stained circle and subtract the inner diameter of the ring. Divide the result by 2 to obtain the width of the stained ring in units of 0,5 mm. 9
44、Expression of results Report the mean stained ring width of the two test rings for the sample, rounded to the nearest 0,5 mm. 10 Precision 10.1 Repeatability The difference between two successive results, obtained by the same operator with the same apparatus under constant operating conditions on id
45、entical test material would, in the long run, in the normal and correct operations of the test method, differ by more than 0,5 mm in only one case in twenty. 10.2 Reproducibility The difference between two single and independent results obtained by different operators working in different laboratori
46、es on identical test material would, in the long run, in the normal and correct operation of the test method, differ by more than 1,0 mm in only one case in twenty. 11 Test report The test report shall contain at least the following information: a) type and complete identification of the sample under test; b) reference to this European Standard; c) result obtained (see Clause 9); d) any deviation, by agreement or otherwise, from the procedure specified; e) date of the test.
