Tests for general properties of aggregates - Common equipment and calibration Ingestion-build-47786 What is BS EN 12814-31 Scope This European Standard specifies general requirements for common equipment, calibration and checking procedures and reagents for the testing of the properties of aggregates. In the case of checking, other procedures than the ones described in this standard may be used provided that appropriate working relationships with the corresponding methods described in this standard have been established. In case of dispute, the checking methods
