13、oreword This European Standard has been prepared by the Technical Committee CEN/TC 154 “Aggregates“ of which the Secretariat is held by BSI. This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by May 199

14、6, and conflicting national standards shall be withdrawn at the latest by May 1996. This Standard forrns part of a series of tests for geometrical properties of aggregates. Test methods for other properties of aggregates are covered by Parts of the following European Standards: prEN 932 prEN 1097 pr

In cases of dispute a reference test should be carried out using perforated plate sieves. Page 4 EN 933-2 : 1995 5 Nominal size of apertures When a par

23、ticle size distribution is carried out, sieves from the following series of aperture sizes between d and D of the designated product size, shall be included, in addition to any other required sieves: O,063mm,0,125mm,0,25Omm,0,500mm, lmm,2mm,4mm,8mm, 16m, 31,5 mm, 63 mm, 125 mm For tests where particular sieves are required these shall be selected from the R 20 series specified in IS0 565. NOTE: The R 20 series from 0,063 mm to 125 mm increases by step ratio lom = 1.12. 6 Shape of apertures Only sieves with square apertures shall be used.
