DIN EN 933-1
Tests for geometrical properties of aggregates - Part 1: Determination of particle size distribution - Sieving method; German version EN 933-1:2012

Title (German)

Prüfverfahren für geometrische Eigenschaften von Gesteinskörnungen - Teil 1: Bestimmung der Korngrößenverteilung - Siebverfahren; Deutsche Fassung EN 933-1:2012

Overview

This European Standard describes the reference washing and dry sieving method used for type testing and in case of dispute, for determination of the particle size distribution of aggregates. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. The method does not apply to fillers. The determination of the grading of fillers is specified in EN 933-10 "Assessment of fines - Grading of filler aggregates (air jet sieving)". Dry sieving without washing may be used for aggregates free from particles which cause agglomeration. The test consists of dividing and separating a material into several particle size classifications of decreasing sizes by means of a series of sieves. The aperture sizes and the number of sieves shall be selected in accordance with the nature of the sample and the accuracy required. The method adopted is washing and dry sieving. When washing can alter the physical properties of a lightweight aggregate, dry sieving shall be used and the procedure specified in 7.1 shall not be applied. The mass of the particles retained on the various sieves is related to the initial mass of the material. The cumulative percentages passing each sieve are reported in numerical form and, when required, in graphical form (grading curve). This document (EN 933-1:2012) has been prepared by Technical Committee CEN/TC 154 "Aggregates", the secretariat of which is held by BSI (United Kingdom). The responsible German committee is Working Committee NA 062-03-13 AA "Joint Working Committee: Gesteinskörnungen; Prüfverfahren, Petrographie, Probenahme und Präzision" ("Aggregates; test methods, petrography, sampling and precision") at the Materials Testing Standards Committee (NMP) at DIN. The following modifications have been made with respect to DIN EN 933-1:2006-01: a) permission of other test methods, for example, for factory production control, in the scope; b) standard has been editorially revised.
