ÖNORM EN 13383-1

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. It provides for the evaluation of conformity of the products to this European Standard. NOTE 1 Armourstone used in construction should comply with all the requirements of this European Standard. As well as familiar and traditional natural and manufactured armourstone Mandate M/125 Aggregates included recycled armourstone and some materials from new or unfamiliar sources. Recycled armourstone are included in the standards and new test methods for them are at an advanced stage of preparation. For unfamiliar materials from secondary sources, however, the work on standardisation has only started recently and more time is needed to define clearly the origins and characteristics of these materials. In the meantime such unfamiliar materials when placed on the market as armourstone must comply fully with this standard and national regulations for dangerous substances (see Annex ZA of the standard) depending upon their intended use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents. NOTE 2 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.
