Armourstone. Specification (British Standard)
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 products that have been considered and are within the scope of this European Standard is given in Annex A.This European Standard specifies that a quality control system is in place for use in factory production control and it provides for the evaluation of conformity of the products to this European Standard.It incorporates a general requirement that armourstone shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination.NOTE 1Armourstone used in construction should comply with all the requirements of this European Standard. The standard includes specific requirements for natural armourstone, ferrous and steel making slag and recycled armourstone. For materials from some other secondary sources, however, work is ongoing and the requirements are incomplete. In the meantime, such materials, when placed on the market as armourstone, should comply fully with this European Standard but may also be required to conform to specific relevant additional requirements at the place of 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 2Finer 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.NOTE 3Requirements for the declaration of the potential of armourstone to release regulated dangerous substances are currently under development. Until such time as these are finalised, attention should be paid to requirements at the place of use.
