15、 of which is held by AFNOR/BNP. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2010, and conflicting national standards shall be withdrawn at the latest by November 2010. Attention is dr
16、awn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13702-1:2003. This document was formerly known as EN 13702 Part 1. As Par
17、t 2 of this standard was merged with another standard into EN 13302, this standard was renumbered into EN 13702. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgari

20、er. Although the method has been developed for modified binders, it is also suitable for other bituminous binders. NOTE Unlike penetration grade bitumen, polymer modified bitumens (PMBs) may not show a straight line on the Heukelom-Diagram. This implies that in order to obtain information about the
21、temperature susceptibility of PMBs, viscosity should be measured at different temperatures. WARNING The 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 i
22、s 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. 2 Normative references The following referenced documents are indispensable for the application of this document. Fo
23、r dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders Sampling bituminous binders EN 12594, Bitumen and bituminous binders Preparation of test samples 3 Princ
24、iple The sample is placed on a plate, a cone is pressed onto the sample and the system is brought to the test temperature. A stress is applied to the sample by rotation. The torque is measured from the applied shear rate and dynamic viscosity is calculated by: =(1) where is the shear rate expressed
25、in s-1; is the stress expressed in Pa, calculated by: dMA= (2) where A is the cone factor expressed in m-3; Mdis the torque in expressed N m. NOTE The advantages of this method are the use of a very small sample and the speed of the method, especially regarding thermal conditioning of the specimen.

27、5Pa s; range of temperature: 60 C to 150 C. The sample temperature shall be maintained within 0,5 C up to 100 C and within 1,0 C above 100 C. 5 Sampling Take the sample in accordance with EN 58 and prepare the sample in accordance with EN 12594. 6 Procedure Select the appropriate size (diameter and
28、angle) of cone to allow measurement at the selected shear rate. Place the sample on the plate and press the selected cone onto the sample. Remove any surplus sample and bring the system to the test temperature. Commence the first measurement at the lowest temperature: Temperature: (60 0,5) C; Shear
29、rate: 5 x 10-2s-1. Check the reading after a delay of 15 min when reaching the temperature and note the temperature, the cone size, the shear rate and the reading. Repeat the test and calculate the result as an average of two tests. Replace the specimen and increase the temperature to the next test
30、temperature. Commence the second measurement: Temperature: (100 0,5) C; Shear rate: 5 x 101s-1. Replace the specimen and increase the temperature to the next test temperature. Commence the third measurement: Temperature: (150 1,0) C; Shear rate: 5 x 102s-1. It should be ensured that the complete spe
31、cimen has reached the test temperature before starting the test. The sample should not contain any filler. NOTE In addition to these test temperatures and shear rates any other temperature and shear rate can be used. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 12/01/2011 06:50, Uncontroll

Express the viscosity values in Pa s as follows: (1,000 x 10x) Pa s. 8 Precision NOTE The following prec
33、ision data are the best currently estimated and are proposed until results of further round robin tests are available. 8.1 Repeatability The difference between two successive results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material
34、 would, in the long run, in the normal and correct operation of the test method, differ by more than 5 % in only one case in twenty. 8.2 Reproducibility The difference between two single and independent results, obtained by different operators working in different laboratories on identical test mate
35、rial would, in the long run, in the normal and correct operation of the test method, differ by more than 15 % in only one case in twenty. 9 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
36、 European Standard; c) temperature, shear rate and the result of the test (see Clause 7); d) diameter and angle of the cone; e) date of the test; f) any deviation, by agreement or otherwise, from the specified procedure.
