The purchaser should advise the supplier of any preference for a particular general colour for the armourstone. 6 Chemical requirements 6.1 General The necessity for testing and declaring all properties in this clause shall be limited according to the particular application at end use or origin of the aggregate. When required, the tests specified in Clause 6 shall be carried out to determine appropriate chemical properties. NOTE This clause generally applies to natural and manufactured armourstone. However, some recycled materials could have other chemical characteristics that do not apply to the generality of armourstone with an established pattern of use and when required, provisions valid at the place of use can be used to assess its suitability. Sampling shall be carried out as specified in EN 13383-2:2013, Clause 4. 6.2 Impurities Armourstone shall not contain any foreign matter such as scrap metal, wood and plastic in a quantity that will cause damage to the structure or the environment in which it is used (see EN 16236:2013, Table 3). 6.3 Water soluble constituents When a determination of water soluble constituents is required, an eluate shall be prepared from a representative sample of armourstone as specified in EN 1744-3.

If one of the tested pieces shows more than 0,5 % loss of mass or formation of open cracks, another 10 pieces of armourstone shall be tested. NOTE 1 The pieces tested in conformity with 7.3 and showing maximum 0,5 % water absorption are excluded from further testing.

Source materials considered in the development of EN 13383-1 and their status in respect of the scope of this European Standard The source types listed in this annex have been considered in the preparation of this European Standard. Their status within the standard is indicated in Table A. Source materials not described here are outside the scope of EN 13383-1. Sources with no history of use as armourstone are outside the scope of the standard and should not be used as armourstone in conformity with this standard and are therefore gray shaded in Table A.1. Sources with positive history of use and no identification of the need for additional requirements are fully within the scope of the standard. Sources with a positive history of use and where the need for additional requirements has been identified are provisionally within scope pending the inclusion of suitable test methods and requirements. In all cases there is an obligation to control the potential release of regulated dangerous substances (RDS) in accordance with Member State requirements at the place of use. The information in this annex is based on a comprehensive survey of the use of armourstone from secondary sources in European member states undertaken between 2000 and 2005 and subsequent corrections identified by CEN/TC 154. CEN/TC 154 intends to keep this inventory under continual review. Any relevant information to assist in the updating of this annex including any proposal for the inclusion of new source types should be submitted to the secretariat of CEN/TC 154. In situations where the need for additional requirements has been identified, such materials, when placed on the market as aggregates, shall comply fully with this European Standard but may also be required to comply with 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. Under an extension to its Mandate, CEN/TC 154 is currently developing requirements for the declaration of the potential of aggregates to release regulated dangerous substances under Essential Requirement 3. It is anticipated that the source classifications in this annex will be used as the basis of families for the collation of data and the development of source specific requirements for regulated dangerous substances. Any input to this process should be made through the secretariat of CEN/TC 154.

Guidance on block integrity C.1 General “Block integrity” is the name given to the property of each block or piece of armourstone indicating its wholeness or, in practical terms, its resistance to breaking apart along flaws or fissures during routine handling, placement and under wave loading in the works. The importance of block integrity increases with the size of the armourstone, becoming the most important mechanical property for heavy armourstone. This annex provides information on methods for the control of block breakage resulting from the presence of significant flaws within pieces of armourstone. As a result of its geological origin and the range in possible methods of extraction, pieces of armourstone may contain natural or blast-in
