This European Standard shall be gi
17、ven the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2001, and conflicting national standards shall be withdrawn at the latest by December 2003. This European Standard forms part of series of tests for bituminous bound filler
18、aggregates. Test methods for other properties of aggregates will be covered by parts of the following European Standards: EN 932 EN 933 EN 1097 EN 1367 EN 1744 Tests for general properties of aggregates; Tests for geometrical properties of aggregates; Tests for mechanical and physical properties of
19、aggregates; Tests for thermal and weathering properties of aggregates; Tests for chemical properties of aggregates. The other part of EN 131 79 will be: Part 1 : Delta ring and ball test. According to the CENCENELEC Internal Regulations, the national standards organizations of the following countrie
20、s are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

26、iple A filler aggregate mixture placed in a cylindrical cup is penetrated for 5 s with an aluminium stamp 8 mm in diameter with a mass of 15 g. The amount of water required to give a penetration of the stamp in the mixture between 5,O mm and 7,O mm is determined. Q BSI 10-2000 STD.BS1 BS EN L3L7-?-E

28、 diameter, with a flat bottom (65 f 5) mm in diameter. 5.4 50 ml burette. 5.5 Flexible spatula. 5.6 Cylindrical cup, inner diameter (30 f 1) mm, height (30 f I) mm with a wall thickness of (2,O f 0,2) mm. 5.7 Penetrometer, complying with EN 1426. 5.8 Round aluminium stamp, (8,O f 0,l) mm in diameter
29、, mass (15,O f 0,2) g, fitting into the penetrometer in place of the needle holder. 5.9 Timer, accurate to 0,l s. 5.10 Demineralized water. 6 Preparation of test portions Reduce the undried laboratory sample to test portions in accordance with EN 932-2. At least three test portions with a mass of at
30、 least 50 g are required. NOTE A mechanical sampler can be used. 7 Proced Ure Weigh (50,O f 0,l) g of undried filler in the stainless steel dish and addxl ml of demineralized water from the burette. Mix and stir for (300 f IO) s with the spatula. NOTE I x1 is the expected amount of water required to
31、 give a valid value of penetration of the stamp into the mixture. NOTE 2 Care should be taken to spread the mixture as little as possible to prevent the water from evaporating. Fill the cylindrical cup with the mixture, ensuring that no air bubbles are entrapped and smooth the surface. Place the cup
32、 with the mixture on the base of the penetrometer. Level the bottom of the stamp with the surface of the mixture, reset the dial to zero and allow the stamp to penetrate into the mixture for (5,OIO,l)s. Measure the penetration to the nearest Oll mm and the amount of water from the burette (xi mi) to
33、 the nearest 0,l ml. If the penetration is smaller than 5,O mm or greater than 7,O mm, mix a further test portion with an adjusted volume of water (x2 mi) and repeat the procedure specified in this clause.
