DIN EN 933-10:2009-10 EN 933-10:2009 (E) 4 1 Scope This European Standard describes the
22、 reference method used for type testing and in cases of dispute for determining the particle size distribution up to 2 mm size of natural or manufactured origin filler aggregate using air jet sieving. For other purposes, in particular factory production control, other methods may be used provided th
23、at an appropriate working relationship with the reference method has been established. NOTE A wet sieving procedure conforming to EN 933-1 can be used as an alternative method. However, this procedure is not applicable for mixed filler. 2 Normative references The following referenced documents are i
24、ndispensable for the application of this document. For dated references, only the edition cited applies.

26、is document, the following terms and definitions apply. 3.1 filler aggregate aggregate, most of which passes a 0,063 mm sieve 3.2 laboratory sample sample intended for laboratory testing 3.3 test portion sample used as a whole in a single test 3.4 constant mass successive weighings after drying at l
27、east 1 h apart not differing by more than 0,1 % NOTE In many cases constant mass can be achieved after a test portion has been dried for a pre-determined period in a specified oven at (110 5) C. Test laboratories can determine the time required to achieve constant mass for specific types and sizes o
28、f sample dependent upon the drying capacity of the oven used. 4 Principle The test consists of dividing up and separating, by means of a series of sieves, a filler aggregate into several granular classifications of decreasing sizes. The aperture sizes and the number of sieves are DIN EN 933-10:2009-
29、10 EN 933-10:2009 (E) 5 specified in 5.2. The test is in particular well suited for materials which when dry neither tend to agglomeration nor to electrostatic charge. The method adopted is dry air jet sieving. The mass of the particles passing each sieve is related to the initial mass of the materi
30、al. The percentages obtained are used either in their numerical form or in a graphical form. 5 Apparatus 5.1 All apparatus, unless otherwise stated, shall conform to the general requirements of EN 932-5. 5.2 Test sieves, with round frame of 200 mm nominal diameter and square aperture sizes of 0,063
31、mm, 0,125 mm and 2 mm in accordance with EN 933-2. 5.3 Air jet sieving apparatus, (general form shown in Figure 1) with a pressure difference of (3,0 0,5) kPa across the sieve, during the test procedure. 5.4 Ventilated oven, thermostatically controlled to maintain a temperature of (110 5) C or other
32、 suitable equipment for drying the filler aggregate, if it does not cause any particle breakdown. 5.5 Balance, accurate to 0,1 % of the test portion mass. 5.6 Soft brush. 5.7 Plastic hammer (optional). 6 Preparation of test portions Laboratory samples shall be reduced in accordance with EN 932-2 to
33、produce test portions. The test portion shall have a mass of (50,0 1,0) g. Dry the test portion at (110 5) C to constant mass. Allow to cool, weigh and record as M1.7 Procedure Fit the 0,063 mm test sieve onto the apparatus and transfer all of the test portion onto the sieve. After covering the siev
34、e with the plexiglass lid, operate the air jet sieving apparatus until complete sieving is achieved. A minimum of 3 min is required. During sieving the pressure difference to normal air pressure in the air jet sieving apparatus shall be (3,0 0,5) kPa. NOTE 1 Any agglomeration of particles during sie
35、ving can be alleviated by tapping the plastic hammer at the centre of the plexiglass lid. NOTE 2 The sieving process is complete when the mass of retained material does not change more than 0,1 % of the mass of the test portion during 1 min of this sieving operation. NOTE 3 In many cases sieving can
36、 be completed after sieving for a pre-determined time. Test laboratories can determine the time required to fulfil the requirements of Clause 7 for completion of sieving for specific types and sizes of test portions in the air jet sieving apparatus used.

Repeat the above procedure with the 0,125 mm sieve and then with the 2 mm sieve, using in each case the retained material from the previous sieve and record the masses retained as
