CEN-NORD/TC 154 Mirror Groups Meeting Product standards: Merge of EN 13242, EN 13043, EN 12620 and (possibly) EN 13450 – one aggregate standard instead of one per use. Interaction between EN 13242 and EN 13285 Separate but Compatible ! Harmonization of EN 13285 ? Test methods: Possible future modifications – Resolution TC 154/SC 6 - Scope of each Test Method (5 year review) is to include following statement: ”This standard describes the reference method used for type testing and in case of dispute for determination of property XX. For other purposes, in particular FPC, other methods may be used provided that an appropriate working relationship with the reference method has been established.

CEN-NORD/TC 154 Mirror Groups Meeting Test methods – proposed work items Petrographic analysis - Replacement/complement to Petrographic description - Recomendation for use (concrete, unbound, asphalt etc.) - Mica content/distribution Humus content (e.g. Loss on ignition) Harmul fines (Sed. Analys) Nordic Ball Mill for Unbound …. Minimum MD- values (gravel surface layer) Limiting amount of cubical particles Mechanised sieving Other …………
