It applies to overstabilized cationic bi

19、tuminous emulsions and to slow-setting and overstabilized anionic bituminous emulsions. WARNING The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility o

20、f the user of this 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.

28、ordance with EN 58 and prepared in accordance with EN 12594. 8 Procedure 8.1 General Carry out the procedure under normal laboratory conditions, between 18 C and 28 C. 8.2 Sieving of cement Filter the cement (Clause 5) using the 0.16 mm sieve specified in sub-clause 6.2. Take the cement that passed

29、through the sieve, dry it in the oven (6.8) at (110 5) C. Keep in a dessicator or a water tight container before the test. 8.3 Test Wash the 2 mm mesh sieve (6.1) and pan (6.3) and dry them in the oven (6.8) for 30 min. Cool in a dessiccator and weigh the sieve and pan together (m1). Weigh (50,0 0,1

30、) g of cement, into the round bottomed dish (6.4). Add 100 ml of the bituminous emulsion test sample and stir immediately for 1 min in a circular motion at the rate of one turn per second. Add 150 ml of water and stir for a further 3 min at the same rate. Pour the mixture through the 2 mm mesh sieve

31、 (6.1), ensuring that all of the mixture is removed from the round bottomed dish by repeatedly washing with water. When all of the mixture has been transferred from the round bottomed dish, rinse the sieve with further water by pouring this from a height of (150 5) mm until the washings are clear. F

32、it the sieve onto the pan and dry them in the oven (6.8) for 1 h. Cool in a dessiccator and reweigh. Repeat this procedure until the mass (m2) is constant (less than 0,1 g difference between weighing). 9 Calculation Calculate the mixing stability with cement, Sc, of the test sample, in grams, by mea

33、ns of the following equation: SC= m2- m1where: m1is the mass of the sieve and pan, in grams; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 04/08/2009 02:32, Uncontrolled Copy, (c) BSIBS EN 12848:2009EN 12848:2009 (E) 6 m2is the mass of the sieve and pan and sample after drying, in grams. 10

34、 Expression of results Express the result, obtained in accordance with Clause 9, in grams, rounded to the nearest 0,1 g. 11 Precision NOTE 1 The precision of the method was evaluated in accordance with EN ISO 4259 1. NOTE 2 The precision data are extracted from NF T 66-024 2. 11.1 Repeatability The

35、difference between two successive 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 operation of the test method, exceed 0,2 g in only one case in twenty. 11.2 Reproduci

36、bility 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 operation of the test method, exceed 0,4 g in only one case in twenty. 12 Test report The te

37、st 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 of the test (see Clause 10); d) any deviation, by agreement or otherwise, from the procedure specified; e) date of sampling, dat
