It incorporates a general requirement that aggregates will 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. The tables in this standard include categories which are common across the four main aggregate standards: EN 12620, EN 13043, EN 13139 and EN 13242. Not all of these categories are appropriate for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Categories, notes, comments etc, which are shown grey shaded should not be used for aggregates for use in hydraulically bound and unbound materials for civil engineering works and road constructions. Aggregates used in hydraulically bound and unbound materials for civil engineering works should comply with all the requirements of this European Standard. The standard includes comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitution of recycled aggregates. 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 aggregates, should conform fully to this 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 Requirements for lightweight aggregates are specified in prEN 13055. Requirements for the declaration of the potential of aggregates 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

4.3 Grading 4.3.1 General The grading of the aggregate, when determined in accordance with EN 933-1, shall conform to the requirements of 4.3.2 to 4.3.5 as appropriate to its aggregate size d/D. Aggregates may comprise single sizes, all-in aggregates or combinations of two or more than two sizes. Aggregates supplied as a mixture of different sizes or types should be uniformly blended. When aggregates of significantly different density are blended, caution is necessary to avoid segregation. When assessing aggregates within a system of factory production control, at least 90 % of gradings, taken on different batches within a maximum period of 6 months, shall fall within the limits specified in Table 2 to Table 5 for tolerances on manufacturer declared typical gradings. Size designations and grading categories are essentially categories of convenience and different sizes and grading categories may be used by agreement between supplier and purchaser.

5 Physical requirements 5.1 General The necessity for testing and declaring all properties specified 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 5 shall be carried out to determine appropriate physical properties. When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g. a Los Angeles coefficient of say 65 corresponds to LA70. NOTE 1 When a property is not required, a “No requirement” category can be used. SIST EN 13242:2013

When required, the impact value shall be determined in accordance with EN 1097-2 and the results declared in accordance with the relevant category specified in Table 14 according to the particular application or end use. SIST EN 13242:2013

5.3 Resistance to wear When required, the resistance to wear (Micro-Deval coefficient - MDE) shall be determined in accordance with EN 1097-1 and the results declared in accordance with the relevant category specified in Table 15 according to the particular application or end use.

5.4 Particle density and water absorption 5.4.1 Particle density When required, the particle density shall be determined in accordance with EN 1097-6 (apparent particle density) and the results declared. 5.4.2 Water absorption When required, the water absorption shall be determined in accordance with EN 1097-6 depending upon the size of the aggregate and the results declared. 5.5 Bulk density When required, the bulk density shall be determined in accordance with EN 1097-3 and the results declared. 5.6 Water suction height When required, the water suction height shall be determined in accordance with EN 1097-10 and the results declared. 6 Chemical requirements 6.1 General The necessity for testing and declaring all properties specified 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. When the value of a property is required but not defined by specified limits the value should be declared as an XXDeclared category, e.g. a value of say 1,2 % by mass for the acid-soluble sulfate content of air-cooled blast furnace slag corresponds to AS1,2 (Declared category). NOTE 1 When a property is not required, a “No requirement” category can be used. NOTE 2 Guidance on selection of appropriate categories for specific applications can be found in national provisions in the place of use of the aggregate. NOTE 3 Where conformity with a category is based on a value of a property being less than or equal to a given value, conformity with a more severe category (lower value) automatically confers conformity with all less severe categories (higher values). Similarly for categories based on the value of a property being greater than or equal to a given value, SIST EN 13242:2013
