Tests for mechanical and physical properties of aggregates - Part 7: Determination of the particle density of filler - Pyknometer method

This standard describes the reference method used for type testing and in cases of dispute for the determination of the particle density of filler by means of a pyknometer. 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.

Prüfverfahren für mechanische und physikalische Eigenschaften von Gesteinskörnungen - Teil 7: Bestimmung der Rohdichte von Füller - Pyknometer-Verfahren

Diese Norm beschreibt das Bezugsverfahren für die Typprüfung und in Streitfällen für die Bestimmung der
Dichte von Füllern mit dem Pyknometer. Für andere Zwecke, insbesondere die werkseigene
Produktionskontrolle, dürfen andere Verfahren angewendet werden, falls eine geeignete Arbeitsbeziehung mit
dem Bezugsverfahren nachgewiesen wurde.

Essais pour déterminer les caractéristiques mécaniques et physiques des granulats - Partie 7: Détermination de la masse volumique absolue du filler - Méthode au picnomètre

La présente norme décrit la méthode de référence utilisée pour les essais de type et, en cas de conflit, pour la détermination de la masse volumique réelle du filler au moyen d’un pycnomètre. Pour d'autres objectifs, en particulier dans le cadre du contrôle de la production en usine, d'autres méthodes peuvent être employées si une corrélation appropriée avec la méthode de référence a été établie.

EN 1097-7:2008 (E) 3 Foreword This document (EN 1097-7:2008) 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of an identical text or by endorsement, at the latest by September 2008, and conflicting national standards shall be withdrawn at the latest by September 2008. 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 1097-7:1999. This European Standard forms part of a series of standards for tests for mechanical and physical properties of aggregates. Test methods for other properties of aggregates will be covered by parts of 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 The other parts of EN 1097 will be: 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 Part 5: Determination of the water content by drying in a ventilated oven Part 6: Determination of particle density and water absorption Part 8: Determination of the polished stone value Part 9: Determination of the resistance to wear by abrasion from studded tyres - Nordic test Part 10: Determination of water suction height According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 1097-7:2008 (E) 4 1 Scope This standard describes the reference method used for type testing and in cases of dispute for the determination of the particle density of filler by means of a pyknometer. 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 932-2, Tests for general properties of aggregates - Part 2: Methods for reducing laboratory samples EN 932-5, Tests for general properties of aggregates - Part 5: Common equipment and calibration ISO 3507, Laboratory glassware - Pyknometers 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 laboratory sample reduced sample derived from a bulk sample for laboratory testing

3.2 test portion sample used as a whole in a single test 3.3 test specimen sample used in a single determination when a test method requires more than one determination of a property 3.4 constant mass successive weighings after drying at least 1 h apart not differing by more than 0,1 % NOTE In many cases constant mass can be achieved after a test portion has been dried for a pre-determined period in a specified oven (see 6.6) at (110 ± 5) °C. Test laboratories can determine the time required to achieve constant mass for specific types and sizes of sample dependent upon the drying capacity of the oven used. 3.5 particle density of filler mass per volume unit of filler excluding any trapped air 3.6 filler aggregate aggregate, most of which passes a 0,063 mm sieve, which can be added to construction materials to provide certain properties SIST EN 1097-7:2008

EN 1097-7:2008 (E) 5 4 Principle The pyknometer method is a well known method for determining the volume of irregularly formed samples, e.g., aggregate. When the mass of the sample is known, the density can be calculated. The principle is based on the replacement of a certain amount of liquid of known density with th
