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14、6, and conflicting national standards shall be withdrawn at the latest by May 1996.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
15、EN 1367 prEN 1744 Tests for general properties of aggregates Tests for mechanical and physical properties of aggregates Tests for thermal and weathering properties of aggregates Tests for chemical properties of aggregates According to the CENKENELEC Internai Regulations, the following countries are
16、bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

17、ominal aperture sizes and shape for woven wire cloth and perforated plate in test sieves used for test methods for aggregates. It applies to aggregates of natural or artificial origin including lightweight aggregates. 2 Normative references This European Standard incorporates by dated or by undated

Below 4 mm they shall be woven wire test sieves conforming to IS0 33
22、10-1. NOTE: Woven wire sieves of 4 mm and above may be used if a correlation can be established with results obtained using perforated plate sieves. 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.
