Characterization of bulk materials - Determination of a size-weighted fine fraction and crystalline silica content - Part 2: Calculation method

This document specifies the determination of the size-weighted fine fraction (SWFF) and the size-weighted fine fraction of crystalline silica (SWFFCS) in bulk materials by calculation. The document also specifies the assumptions and preconditions to be fulfilled for this method to be valid.
The purpose of this document is to allow users to evaluate bulk materials regarding their size-weighted fine fraction and crystalline silica content.
NOTE   For preparation of the sample and determination of crystalline silica by X-ray Powder Diffractometry (XRD) or Fourier Transform Infrared Spectroscopy (FT-IR), see EN 17289-1.
The calculation method is applicable only after experiments have shown that the results are accurate and consistently equal or higher than the results from sedimentation, as specified in EN 17289 3, for that particular bulk material.
A specific method for the evaluation of the SWFF for diatomaceous earth bulk materials is given in Annex A. Due to the internal porosity of diatomaceous earth, the general instructions given in this document are adapted in order to take into account the material’s effective density.
This document is applicable for crystalline silica containing bulk materials which have been fully investigated and validated for the evaluation of the size-weighted fine fraction and crystalline silica.

Charakterisierung von Schüttgütern - Bestimmung einer größengewichteten Feinfraktion und des Anteils an kristallinem Quarz - Teil 2: Berechnungsverfahren

Dieses Dokument legt die Bestimmung der größengewichteten Feinfraktion (SWFF) und der größengewichteten Feinfraktion von kristallinem Quarz (SWFFCS) in Schüttgütern durch Berechnung fest. Das Dokument legt auch die Annahmen und Voraussetzungen fest, die zu erfüllen sind, damit dieses Verfahren gültig ist.
Der Zweck dieses Dokuments besteht darin, Anwendern die Bewertung von Schüttgütern hinsichtlich deren größengewichteter Feinfraktion und des Gehalts an kristallinem Quarz zu ermöglichen.
ANMERKUNG   Zur Probenvorbereitung und zur Bestimmung von kristallinem Quarz durch Röntgenpulver-diffraktometrie (XRD) und Fourier-Transformations-Infrarot-Spektroskopie (FT IR) siehe EN 17289-1.
Das Berechnungsverfahren ist nur anwendbar, nachdem Experimente gezeigt haben, dass die Ergebnisse genau und durchweg gleich sind oder höher ausfallen als die für dieses spezielle Schüttgut durch Sedimentation erzielten Ergebnisse, wie in EN 17289-3 festgelegt ist.
Ein spezifisches Verfahren zur Bewertung des SWFF für Schüttgüter aus Diatomeenerde ist in Anhang A angegeben. Aufgrund der inneren Porosität von Diatomeenerde, sind die in diesem Dokument enthaltenen allgemeinen Anweisungen angepasst, um die effektive Dichte des Materials zu berücksichtigen.
Dieses Dokument ist für kristallinen Quarz enthaltende Schüttgüter anwendbar, die zur Bewertung der größengewichteten Feinfraktion und des kristallinen Quarzes untersucht und validiert wurden.

Caractérisation des matériaux en vrac - Détermination de la fraction fine pondérée par taille et de la teneur en silice cristalline - Partie 2 : Méthode par calcul

Le présent document spécifie la détermination par calcul de la fraction fine pondérée par taille (SWFF) et de la fraction fine de silice cristalline pondérée par taille (SWFFCS) dans des matériaux en vrac. Le document spécifie également les hypothèses et les conditions préalables à respecter pour que cette méthode soit valable.
L’objectif du présent document est de permettre aux utilisateurs d’évaluer des matériaux en vrac en ce qui concerne leur fraction fine pondérée par taille et leur teneur en silice cristalline.
NOTE   Pour la préparation de l’échantillon et le dosage de la silice cristalline par l’analyse de poudre par diffraction de rayons X (XRD) ou la spectroscopie infrarouge à transformée de Fourier (FT-IR), voir l’EN 17289-1.
La méthode par calcul n’est applicable qu’après avoir démontré, par des expériences, que les résultats sont exacts et constamment supérieurs ou égaux aux résultats obtenus par la méthode par sédimentation, telle que spécifiée dans l’EN 17289-3, pour le matériau en vrac considéré.
Une méthode spécifique pour l’évaluation de la SWFF de matériaux en vrac à base de terre de diatomées est donnée dans l’Annexe A. En raison de la porosité interne des terres de diatomées, les instructions générales données dans le présent document sont adaptées afin de prendre en compte la masse volumique effective du matériau.
Le présent document s’applique aux matériaux en vrac contenant de la silice cristalline, qui ont été entièrement étudiés et validés pour l’évaluation de la fraction fine pondérée par taille et de la silice cristalline.
