DIN EN 1097-9:2014-03

This document has been prepared by Technical Committee CEN/TC 154 "Aggregates", the secretariat of which is held by BSI (United Kingdom). The responsible German body involved is Working Committee NA 062-03-13 AA "Gemeinschaftsarbeitsausschuss NA 062/FGSV: Gesteinskörnungen; Prüfverfahren, Petrographie, Probenahme und Präzision" ("Joint working group NA 062/FGSV: Aggregates; test methods, petrography, sampling and precision") at the Materials Testing Standards Committee (NMP). This European Standard describes the reference method, used for type testing and in case of dispute, for determination of the resistance of coarse aggregate to wear by abrasion from studded tyres. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with this reference method has been established. The test is applicable to aggregates with a size fraction of 11,2 mm to 16,0 mm.
