DIN EN 1367-7:2014-07

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 is Working Committee NA 062-03-13 AA "Gemeinschaftsarbeitsausschuss NA 062/FGSV: Gesteinskörnungen; Prüfverfahren, Petrographie, Probenahme und Präzision" ("Joint Working Committee NA 062/FGSV: Aggregates; test methods, petrography, sampling and precision") of the Materials Testing Standards Committee (NMP) at DIN. This European Standard specifies the reference test method used for type testing, and in case of dispute, for determining the resistance to freezing and thawing of lightweight aggregates (LWA) in accordance with EN 13055. For other purposes, in particular for 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 with particle size not less than 4 mm and up to a maximum size of 32 mm.
