DIN EN 1097-11:2013-11

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 standardizing committee 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) at DIN. This European Standard specifies the reference method used for type testing, and in case of dispute, for determining the compressibility and confined compressive strength of lightweight aggregates (LWA). 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 test is applicable to LWA passing the 32 mm sieve.
