Attention is drawn to the poss
16、ibility 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.

20、ence filler. This test method is applicable to low-viscosity 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 of the
21、 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. For dated references, only the edition
22、 cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

23、s of this document, the following terms and definitions apply. 3.1 penetration power ability of a bitumen emulsion to penetrate into a reference filler 3.2 penetration time time, in minutes, required for a specified quantity of bituminous emulsion to penetrate into a defined quantity of a reference
24、filler 4 Principle A specified quantity of the emulsion to be tested is poured onto the reference filler. The time required for the emulsion to penetrate into the filler is measured. 5 Reagents and materials A mixture of specified silica sand and silica filler is used as the reference filler. In the
25、 event of a dispute, the reference filler specified shall be used. 5.1 Sand The silica sand type F 341shall be used as one of the two components of the reference filler. Characteristics are given in Annex A. 1The silica sand type F 34 is the trade name of a product supplied by Quarzwerke GmbH. This
26、information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of the product name. Equivalent products may be used if they can be shown to lead to the same results, or if a correlation between the products has been established. Licensed Cop

A vent, below the glass filter disc, provides pressure compensation when the test apparatus is charge
29、d. The vent shall be cut perpendicular to the vertical axis, with its edges slightly fused. NOTE The vent can be dispensed with if, during the test procedure, the test apparatus is supported.

32、ined at (110 5) C. 6.4 Wooden board, 200 mm x 200 mm x 10 mm in size. 6.5 Stopwatch, graduated in divisions of 1 s or less. 7 Sampling The material under test shall be sampled in accordance with EN 58 and prepared in accordance with EN 12594. The test shall be carried out on two test portions of the
33、 sample, each weighing (10,0 0,1) g (see Clause 8). 8 Procedure 8.1 General Carry out the procedure under normal laboratory conditions, between 18 C and 28 C. 8.2 Test Dry the quantities of silica sand and testing silica filler, required for the test, in the oven (6.3) at a temperature of (110 5) C
34、until constant mass is reached and cool to ambient temperature in a desiccator. For each test portion, mix intimately (50,0 0,1) g of silica sand and (50,0 0,1) g of testing silica filler and transfer via a funnel to the upper part of the test apparatus (6.1), lifting the funnel with increasing fill
35、ing height. Level the surface of the filler mixture in the apparatus by knocking the lower edge of the test apparatus three times on the wooden board (6.4). Place the apparatus on the balance (6.2). Pour (10,0 0,1) g of the emulsion to be tested along a glass rod onto the centre of the filler mixtur
36、e. Pour the entire quantity of emulsion within (10 1) s. Start measuring the time immediately after pouring the emulsion. Cover the test apparatus using a watch glass. Determine the time for the emulsion to completely penetrate into the filler mixture, i.e. when the structure of the filler at its up
37、per surface can be clearly recognised. If penetration of the filler mixture is not completed within 20 min, discontinue the test. Repeat the test procedure using new quantities of filler and emulsion. If the results for both sample portions differ by more than 3 min, repeat the procedure for a third
38、 sample portion. The two values nearest to each other are used to calculate the mean penetration time. 9 Expression of results Express the individual penetration times and the average penetration time, in minutes, to the nearest integer. Express the result as the arithmetic mean of the two individua
39、l results of penetration time, to the nearest integer.

40、ty The 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 3 min in only one case in twenty. 10.2 Re
41、producibility 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 6 min in only one case in twenty (provided that
42、both results have been determined within two weeks). NOTE The source of precision data is DIN 52046 1. 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) reference t
43、o the type of apparatus used; d) reference to the used sand and filler; e) result of the test (see Clause 9); f) any deviation, by agreement or otherwise, from the procedure specified; g) date of sampling, date of sample preparation and date of the test.
