DIN EN 1097-2:2010-07

This document (EN 1097-2:2010) has been prepared by Technical Committee CEN/TC 154 "Aggregates", the secretariat of which is held by BSI (United Kingdom). The responsible national Committee is NA 062-03-13 AA, Mirror Committee of CEN/TC 154 "Aggregates" of the Materials Testing Standards Committee (NMP). EN 1097, "Tests for mechanical and physical properties of aggregates", consists of the following parts: Part 1: Determination of the resistance to wear (micro-Deval) Part 2: Methods for the determination of the resistance to fragmentation Part 3: Determination of loose bulk density and voids Part 4: Determination of the voids of dry compacted filler Part 5: Determination of the water content by drying in a ventilated oven Part 6: Determination of particle density and water absorption Part 7: Determination of the particle density of filler Pyknometer method Part 8: Determination of the polished stone value Part 9: Determination of the resistance to wear by abrasion from studded tyres - Nordic test Part 10: Determination of the water suction height This European Standard describes the reference method, the Los Angeles test, used for type testing and in case of dispute for determining the resistance to fragmentation of coarse aggregates and aggregates for railway ballast (Annex A), and an alternative method, the impact test. 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. This European Standard applies to natural, manufactured or recycled aggregates used in building and civil engineering.
