Overview
This document has been prepared by Technical Committee CEN/TC 154 "Aggregates" the secretariat of which is held by BSI (United Kingdom). The responsible national 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 DIN Standards Committee Materials Testing (NMP). This European Standard specifies the reference method used for type testing, and in case of dispute, for determining the flow coefficient of coarse and fine 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. Examples of advanced test methods can be found in the Bibliography. This European Standard applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine aggregate of size up to 2 mm.
