28、cles retained on a sieve of a mesh size specified in this European Standard 3.2 storage stability ability of a bituminous emulsion not to form more coarse particles within a period specified under an appropriate emulsion specification Note 1 to entry: Storage stability is a different concept than se

29、ttling tendency as defined and measured by EN 12847. Although both phenomena are often linked, an emulsion may settle without modification of particle size distribution (no coalescence of emulsion droplets). Note 2 to entry: The purpose of the limits fixed by the emulsion specification is to ensure

30、that there cannot be any disturbance of the workability of the bitumen emulsion under practical conditions. 4 Principle A known mass of bituminous emulsion is filtered through either a prepared sieve with a mesh size of 0,500 mm or through two prepared sieves with mesh sizes of 0,500 mm and of 0,160

31、 mm. The amount of binder retained on the sieves is weighed after washing and drying. Storage stability is determined as the amount of binder retained on the sieve with a mesh size of 0,500 mm after a defined storage period (n days). 5 Reagents and materials Use only reagents of recognised analytica

34、trimethylammonium bromide. This solution, or the actual aqueous phase, may be used for the preparation of cationic emulsion samples. The solution of 1 % of cetyltrimethylammonium bromide should be prepared slightly above 25 C (but not higher than 30 C). Then it should be stored at a temperature of (

40、. 8 Procedure for the determination of residue on sieving 8.1 General Carry out the procedure under normal laboratory conditions between 18 C and 28 C. 8.2 Residue on the 0,500 mm sieve 8.2.1 Wash the 0,500 mm sieve (6.1) with rinsing agent (5.3) and then with ethanol or methylated spirit (5.4). 8.2

41、.2 Place the sieve on the sieve pan (6.3) and dry in the oven (6.12) for not less than 1 h. 8.2.3 After drying, allow the sieve and the sieve pan to cool within the desiccator (6.13). 8.2.4 Weigh the sieve and the sieve pan together. Record the mass, m1, to the nearest 0,01 g (6.5). 8.2.5 Wet the si

42、eve cloth with solution Sa (5.1) or Sc (5.2) as appropriate. 8.2.6 Drain the sieve thoroughly and place it on a funnel (6.14) which is mounted over the bottle (6.10). 8.2.7 Weigh the container (6.11) and record the mass, mC, to the nearest 1 g (6.4). 8.2.8 Weigh (1 000 5) g of emulsion into the cont

43、ainer and record the mass of emulsion, mE, 0,500, to the nearest 1 g (6.4). 8.2.9 Pour the emulsion through the wetted sieve and allow draining completely. Discard the first 30 ml or 40 ml of the filtered emulsion, in order to avoid any possible modification in the properties of the emulsion resulti

44、ng from the action of the Saor Scsolution. Clear as much as possible the container of the emulsion and reweigh the container. Record the mass, mC, Rto the nearest 1 g (6.4). If the emulsion does not pass through the sieve in 5 min at normal laboratory conditions, it is permitted to deviate from this

45、 procedure by pre-heating and testing the laboratory sample at (60 5) C and/or by diluting the emulsion with either Sasolution (5.1) or Scsolution (5.2) as appropriate, in order to determine residue on sieving. If a dilution is performed, an amount of (500 5) g, weighed to the nearest 1 g (6.4), of

46、Saor Scsolution shall be used. If heating is required, all precautions should be taken to minimize water loss and/or skin formation during this operation. DIN EN 1429:2013-08 EN 1429:2013 (E) 7 In case dilution is performed, adequate adaptations of the procedure and of calculations shall be performe

47、d and documented in the test report. Except for the determination of the residue on the 0,160 mm sieve (8.2), the filtered emulsion shall not be used for any other emulsion test. 8.2.10 Remove the bottle containing the filtered emulsion, and stopper it. NOTE The emulsion filtered in this way will be

48、 used to carry out the second part of the test (see 8.3, when required) and, if not diluted, to carry out all other tests on the emulsion. 8.2.11 Place the sieve on a funnel which is mounted over a 250 ml conical flask (6.8). Wash the residue on the sieve with solution Saor Scuntil the washings run clear. Finally wash with water. 8.2.12 Drain the sieve thoroughly and place it on the sieve pan. Dry in the oven (6.12) for at least 2 h and then cool in the desiccator (6.13) for about 30 min. 8.2.13 Weigh
