13、:2013EN 1429:2013 (E) 3 Foreword This document (EN 1429:2013) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by
14、 endorsement, at the latest by December 2013, and conflicting national standards shall be withdrawn at the latest by December 2013. Attention is drawn 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 f
15、or identifying any or all such patent rights. This document supersedes EN 1429:2009. The main technical changes brought to EN 1429 are as follows: Less stringent precision requirements for the weighing scale to be used in 8.2 and Clause 9. More accurate definition of dilution procedures for viscous
16、emulsions (8.2.9 and 8.3.8). Revision of procedure for determination of the storage stability by sieving (Clause 9). WARNING The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems asso
17、ciated with its use. It is 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. Also, for environmental aspects, it is important to limit the quantities of products, solve
18、nts and energy sources to reduce the emissions in air and water and the wastes to the minimum required for a valid test realisation. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austr

24、lity 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 settling tendency as defined and measured by EN 12847. Although both phenomena are often linked, an emu
25、lsion 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 that there cannot be any disturbance of the workability of the bitumen emulsion under practical condi
26、tions. 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 mm. The amount of binder retained on the sieves is weighed after washing and drying. Storage stabili
27、ty 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 analytical grade and water conforming to grade 3 of EN ISO 3696. BS EN 1429:2013EN 1429:2013 (E) 5 The aqueous
28、 solutions (5.1) and (5.2) may be replaced by aqueous phases of the same ionic structure as the emulsion under test. 5.1 Solution SaAqueous phase solution of nominal 0,01 mol/l of sodium hydroxide (NaOH) containing a nominal 1 % mass fraction sodium oleate. This solution, or the actual aqueous phase
29、, may be used for the preparation of anionic emulsion samples. 5.2 Solution ScAqueous phase solution of nominal 0,01 mol/l of hydrochloric acid (HCl) containing a nominal 1 % mass fraction cetyltrimethylammonium bromide. This solution, or the actual aqueous phase, may be used for the preparation of
30、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 (25 1) C before test. 5.3 Efficient rinsing agent Suitable solvent rinsing agents shall be used. 5.4 Ethano

35、n accordance with EN 58 and shall be prepared in accordance with EN 12594. The sample shall be divided into two portions; for referee purposes, both portions shall be tested (see Clause 11). 8 Procedure for the determination of residue on sieving 8.1 General Carry out the procedure under normal labo
36、ratory 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). 8.2.2 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,
37、 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 sieve cloth with solution Sa (5.1) or Sc (5.2) as appropriate. 8.2.6 Drain the sieve thoroughly and place it on a
38、 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 container and record the mass of emulsion, mE, 0,500, to the nearest 1 g (6.4). 8.2.9 Pour the emulsion through the
39、 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 resulting from the action of the Saor Scsolution. Clear as much as possible the container of the emulsion and reweigh
40、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 procedure by pre-heating and testing the laboratory sample at (60 5) C and/or by diluting the emulsion with ei
41、ther 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 Saor Scsolution shall be used. If heating is required, all precautions should be taken to minimize water loss a
42、nd/or skin formation during this operation. BS EN 1429:2013EN 1429:2013 (E) 7 In case dilution is performed, adequate adaptations of the procedure and of calculations shall be performed and documented in the test report. Except for the determination of the residue on the 0,160 mm sieve (8.2), the fi
43、ltered 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 used to carry out the second part of the test (see 8.3, when required) and, if not diluted, to carry out all other
44、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.
45、12) for at least 2 h and then cool in the desiccator (6.13) for about 30 min. 8.2.13 Weigh the sieve with its sieve pan and residue and record the mass, m2, to the nearest 0,01 g (6.5). 8.3 Particles between 0,500 mm and 0,160 mm 8.3.1 Wash the 0,160 mm sieve (6.2) with rinsing agent (5.3) and then
46、with ethanol or methylated spirit (5.4). 8.3.2 Place the sieve on the sieve pan (6.3) and dry in the oven (6.12) for not less than 1 h. 8.3.3 After drying, allow the sieve and the sieve pan to cool in the desiccator (6.13). 8.3.4 Weigh the sieve and the sieve pan together. Record the mass, m3,to the
47、 nearest 0,001 g (6.6). 8.3.5 Wet the sieve cloth with solution Sa(5.1) or Sc(5.2) as appropriate. 8.3.6 Drain it thoroughly and place it on a funnel which is mounted over a 250 ml conical flask (6.8). 8.3.7 Gently stir the emulsion that was filtered through the 0,500 mm sieve (see 8.2.10). 8.3.8 Pl
48、ace the 200 ml conical flask (6.7) on the balance and weigh into it 50 g, mE, 0,160of filtered emulsion to the nearest 1 g (6.4), then add approximately 50 cm3 of the Saor Scsolution. In case the emulsion has been diluted for determining the residue on the 0,500 mm sieve (8.2.9), weigh into the coni
49、cal flask (6.7) 75 g, mE, 0,160of filtered emulsion to the nearest 1 g (6.4) and add approximately 25 cm3 of the Sa or Scsolution. 8.3.9 Gently stir the diluted emulsion. 8.3.10 Filter the diluted emulsion through the 0,160 mm sieve and proceed as described for filtering with 0,500 mm sieve. Wash the residue on the sieve with solution Saor Scsolution until the washings run clear. Finally wash with water. 8.3.11 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
