Part 1: Determination of particle size distribution — Sieving method;  Part 2: Determination of particle size distribution — Test sieves, nominal size of apertures;  Part 3: Determination of particle shape — Flakiness index;  Part 4: Determination of particle shape — Shape index;  Part 5: Determination of percentage of crushed and broken surfaces in coarse aggregate particles;  Part 6: Assessment of surface characteristics — Flow coefficient of aggregates;  Part 7: Determination of shell content — Percentage of shells for coarse aggregates;  Part 8: Assessment of fines — Sand equivalent test;  Part 9: Assessment of fines — Methylene blue test;  Part 10: Assessment of fines — Grading of filler aggregates (air jet sieving);  Part 11: Classification test for the constituents of coarse recycled aggregate. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

NOTE 1 The determination of the grading of fillers is specified in EN 933-10 Assessment of fines — Grading of filler aggregates (air jet sieving). NOTE 2 Dry sieving without washing may be used for aggregates free from particles which cause agglomeration. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Test laboratories may determine the time required to achieve constant mass for specific types and sizes of sample dependent upon the drying capacity of the oven used. SIST EN 933-1:2012

D = aggregate size in mm NOTE 2 The precision of the test method may be reduced if the test portion size is less than the value in Table 1. In such a case, the test portion size should be stated in the test report (9.2). NOTE 3 For aggregates of particle density higher than 3,00 Mg/m3 (see EN 1097-6), an appropriate correction should be applied to the test portion masses given in Table 1 based on the density ratio, in order to produce a test portion of approxim
