EN 1097-9:2014 (E) 3 Foreword This document (EN 1097-9:2014) has been prepared by Technical Committee CEN/TC 154 “Aggregates”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2014 and conflicting national standards shall be withdrawn at the latest by July 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1097-9:1998. The main technical changes compared to EN 1097-9:1998 are the following: 1) Scope: rewritten to allow the use of other methods under precise conditions; 5) Apparatus: Possibility to use other suitable equipment for drying aggregates than the prescribed ventilated oven. Steel quality has been updated; 6) Preparation of test specimens: rewritten (Mass of test portion: Formula revised, Loading the drum: Order changed); 8) Calculation and expression of results: the re-testing criteria has been amended and supplemented with Dixon test guidelines; 9) Test report: required and optional data have harmonized according to document CEN/TC 154/SC 6 – N 1120. The test procedure specified in this European Standard has been developed in Finland, Norway and Sweden where studded tyres are frequently used during cold seasons. This European Standard forms part of a series of tests for mechanical and physical properties of aggregates. Test methods for other properties of aggregates are covered by the following European Standards: EN 932, Tests for general properties of aggregates EN 933, Tests for geometrical properties of aggregates EN 1367, Tests for thermal and weathering properties of aggregates EN 1744, Tests for chemical properties of aggregates EN 13179, Tests for filler aggregate used in bituminous mixtures EN 1097, Tests for mechanical and physical properties of aggregates, consists of the following parts: — Part 1: Determination of the resistance to wear (micro-Deval) — Part 2: Methods for the determination of resistance to fragmentation — Part 3: Determination of loose bulk density and voids — Part 4: Determination of the voids of dry compacted filler SIST EN 1097-9:2014



EN 1097-9:2014 (E) 4 — Part 5: Determination of the water content by drying in a ventilated oven — Part 6: Determination of particle density and water absorption — Part 7: Determination of the particle density of filler — Pyknometer method — Part 8: Determination of the polished stone value — Part 10: Water suction height — Part 11: Determination of compressibility and confined compressive strength of lightweight aggregates According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

1 Scope This European Standard describes the reference method, used for type testing and in case of dispute, for determination of the resistance of coarse aggregate to wear by abrasion from studded tyres. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. The test is applicable to aggregates with a size fraction of 11,2 mm to 16 mm. NOTE An alternative size fraction 8/11,2 mm for different end uses is given in Annex A. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
