  5. CEN/TC 154 Standards • 8 Product standards • 36 Test method standards

  6. Product standards • EN 13139 Aggregates for Mortar • EN 12620 Aggregates for Concrete • EN 13043 Aggregates for Bituminous Mixtures and Surface Treatments • EN 13242 Aggregates for Unbound and Hydraulically Bound Mixtures • EN 13450 Railway Ballast • EN 13383-1 Armourstone • EN 13055-1 Lightweight Aggregate for Concrete • EN 13055-2 Lightweight Aggregate for bound and unbound

  7. Product standards Scope • Aggregates (natural, manufactured, recycled) • Specifies properties • Categories • Evaluation of conformity

  8. Product standards Properties • Geometrical requirements size, grading, fines content/quality • Physical requirements resistance to fragmentation, chrushing, polishing, abrasion, wear and freeze/thawing, density • Chemical requirements organic, total sulfur

  9. Example - Categories

  10. Evaluation of conformity • Type testing • FPC (normative annex) • System 2+ • System 4 • CE-mark (described in annex ZA)

  11. Test method standards • General testes (EN 932-series) • Geometrical properties (EN 933 series) • Mechanical and physical properties (EN 1097) • Thermal and weathering properties (EN 1367) • Chemical properties (EN 1744-series)

  12. Normative references Product standards EN 932 EN 933 EN 1097 EN 1744 EN 1367 -Petrographic-Calibration -Flakiness-Particle size distr.-Methylene blue -Los Angeles,-PSV-Micro Deval-Density-Abrasion -Alkali reaction-Leaching -Freeze/thawing

  13. TC 154 - Present work • Amendments to incorporate recycled aggregates in the product standards • Revision of EN 13383 -1 and-2 Armourstone started • TG 13 Dangerous substances (release to soil, groundwater, air) • Revision of test method standards • Development of new test methods
