scope:

This European Standard specifies the properties of aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these materials for use as armourstone. A list of the source materials that have been considered and are within the scope of this European Standard is given in Annex A (normative). Requirements for the Assessment and Verification of the Constancy of Performance (AVCP) of armourstone to this European Standard are given in prEN 16236. Armourstone used in construction shouldl conform with all the requirements of this European Standard. The standard includes specific requirements for natural armourstone, ferrous and steel making slag and recycled armourstone. Finer aggregates than specified in this European Standard are used in hydraulic structures. For such aggregates European Standards for other end uses of aggregates should be applied.
