CEN/TC 154/WG 10 - Armourstone

This document specifies sampling and test methods for natural, artificial and recycled aggregates for use as armourstone. This document specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the test method has been established.

This document specifies the characteristics of armourstone for uses, either with or without high safety requirements, in hydraulic structures and other civil engineering works.
This document specifies procedures for assessment and verification of constancy (AVCP) of performances of characteristics of the armourstone as well as marking and labelling of these products.
Armourstone covered in this document are aggregates, obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates.
With regard to the material source and production technique, this document covers natural armourstone (see 3.1.2), manufactured armourstone (see 3.1.3) or recycled armourstone (see 3.1.4). Furthermore, manufactured armourstone are manufactured air-cooled blast furnace slags and manufactured steel slags.
With regard to the size of the armourstone, this document covers armourstone with the following gradings:
(1)   coarse grading (see 3.1.8)
(2)   light grading (see 3.1.9)
(3)   heavy grading (see 3.1.10)
This document does not cover
-   aggregates for railway ballast, as these are specified in prEN 13450-1:2021,
-   aggregates for construction works, as these are specified in prEN 17555-1:2021.

This document specifies sampling and test methods for natural, manufactured and recycled aggregates for use as armourstone. This document specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, it allows for other methods to be used provided that an appropriate working relationship with the test method has been established. This document provides non-contradictory complementary information that can be of use when producing or purchasing armourstone produced according to harmonised standard prEN 13383-1:2021.
NOTE   prEN 13383-1:2021 is also intended to be read in conjunction with the Construction Products Regulations.

This document specifies the characteristics of aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these materials for use as armourstone.
Assessment and Verification of Constancy of Performance (AVCP) of armourstone to this document are given in EN 16236.
Armourstone used in construction is meant to comply with the characteristics of this document. The document includes specific characteristics for natural armourstone, ferrous and steel making slag and recycled armourstone.
Finer aggregates than specified in this document are used in hydraulic structures. For such aggregates European Standards for other end uses of aggregates should be applied.

This European Standard specifies sampling and test methods for natural, artificial and recycled aggregates for use as armourstone. This European Standard specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the test method has been established.

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 1   Armourstone 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 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.
NOTE 3   Requirements 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.
