Workplace exposure - Measurement of dustiness of bulk materials that contain or release respirable NOAA or other respirable particles - Part 4: Small rotating drum method
This document describes the methodology for measuring and characterizing the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions and specifies for that purpose the small rotating drum method.
This document specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data.
The methodology described in this document enables
a) the measurement of the respirable dustiness mass fraction,
b) the measurement of the number-based dustiness index of respirable particles in the particle size range from about 10 nm to about 1 µm,
c) the measurement of the initial number-based emission rate and the time to reach 50 % of the total particle number released during testing,
d) the measurement of the number-based particle size distribution of the released aerosol in the particle size range from about 10 nm to about 10 µm,
e) the collection of released airborne particles in the respirable dustiness mass fraction for subsequent observations and analysis by analytical electron microscopy.
NOTE 1 The particle size range described above is based on the equipment used during the pre-normative research [8].
This document is applicable to the testing of a wide range of bulk materials including powders, granules or pellets containing or releasing respirable NOAA or other respirable particles in either unbound, bound uncoated and coated forms.
NOTE 2 Currently no number-based classification scheme in terms of particle number and emission rate has been established for powder dustiness. Eventually, when a large number of measurement data has been obtained, the intention is to revise the document and to introduce such a classification scheme, if applicable.
NOTE 3 The small rotating drum method has been applied to test the dustiness of a range of materials including nanoparticle oxides, nanoflakes, organoclays, clays, carbon black, graphite, carbon nanotubes, organic pigments, and pharmaceutical active ingredients. The method has thereby been proven to enable testing of a many different materials that can contain nanomaterials as the main component.
Exposition am Arbeitsplatz - Messung des Staubungsverhaltens von Schüttgütern, die alveolengängige NOAA oder andere alveolengängige Partikel enthalten oder freisetzen - Teil 4: Verfahren mit kleiner rotierender Trommel
Diese Europäische Norm enthält die Methodik für die Messung und Charakterisierung des Staubungsverhaltens von Schüttgütern, die Nanoobjekte oder Partikel im Submikrometerbereich enthalten oder unter wiederholbaren und Standardbedingungen freisetzen, und legt zu diesem Zweck das Verfahren mit kleiner rotierender Trommel fest.
Darüber hinaus legt diese Europäische Norm die Auswahl der Instrumente und Vorrichtungen sowie die Verfahren für die Berechnung und Präsentation der Ergebnisse fest. Des Weiteren enthält die Norm eine Anleitung für die Auswertung und Angabe der Daten.
Die in dieser Europäischen Norm festgelegte Methodik ermöglicht
a) die Berechnung des Massenanteils an alveolengängigem Staub,
b) die Messung des zahlenbasierten Staubindex alveolengängiger Partikel im Größenbereich zwischen ungefähr 10 nm und 1 000 nm,
c) die Messung der zahlenbasierten Größenverteilung des freigesetzten Aerosols im Größenbereich zwischen ungefähr 10 nm und 10 µm,
d) die Quantifizierung der ersten Staubemissionsrate und der Dauer bis zur Erreichung von 50 % der während der Prüfung freigesetzten Gesamtpartikelzahl und
e) die Charakterisierung des Aerosols auf der Grundlage seiner Partikelgrößenverteilung und der Morphologie und chemischen Zusammensetzung seiner Partikel.
Diese Europäische Norm gilt für die Prüfung einer Vielzahl unterschiedlicher Schüttgüter einschließlich Pulver, Granulate oder Pellets, die Nanoobjekte oder Partikel im Submikrometerbereich in ungebundener, gebundener und unbeschichteter und beschichteter Form enthalten oder freisetzen.
ANMERKUNG 1 Bisher wurde noch kein zahlenbasiertes Klassifizierungsschema für das Staubungsverhalten von Pulver im Hinblick auf die Partikelzahl und das Emissionsverhalten entwickelt. Schließlich, wenn eine große Anzahl an Messdaten vorliegt, ist beabsichtigt, diese Europäische Norm zu revidieren und ein solches Klassifizierungsschema einzuführen.
ANMERKUNG 2 Das Verfahren mit kleiner rotierender Trommel wurde angewendet, um das Staubungsverhalten verschiedener Materialien, einschließlich Nanopartikeloxide, Nanoplättchen, Organokaolin, Ton, Kohlenschwarz, Graphit, Carbon-Nanoröhrchen, organischer Pigmente und pharmazeutischer aktiver Inhaltsstoffe zu prüfen. Das Verfahren ermöglicht daher nachweislich die Prüfung vieler verschiedener Materialien, die Nanomaterialien als Hauptkomponente enthalten können.
Exposition sur les lieux de travail - Mesurage du pouvoir de resuspension des matériaux en vrac contenant ou émettant des nano-objets et leurs agrégats et agglomérats (NOAA) ou autres particules en fraction alvéolaire - Partie 4: Méthode impliquant l'utilisation d'un petit tambour rotatif
Le présent document décrit la méthodologie permettant de mesurer et de caractériser le pouvoir de resuspension de matériaux en vrac contenant ou émettant des NOAA ou autres particules en fraction alvéolaire dans des conditions normalisées et reproductibles et spécifie, à cette fin, le but de la méthode du petit tambour rotatif.
Le présent document spécifie le choix des instruments et dispositifs ainsi que les procédures de calcul et d’expression des résultats. Il fournit également des lignes directrices concernant l’évaluation et la consignation des données.
La méthodologie décrite dans le présent document permet :
a) le mesurage de la fraction massique des poussières alvéolaires ;
b) le mesurage de l’indice du pouvoir de resuspension en nombre de particules alvéolaires dans la plage granulométrique comprise entre environ 10 nm et 1 µm ;
c) le mesurage du taux initial d’émission en nombre et du temps nécessaire pour atteindre 50 % du nombre total de particules libérées au cours des essais ;
d) le mesurage de la distribution granulométrique en nombre des particules d’aérosol libérées dans la plage granulométrique comprise entre environ 10 nm 10 µm ;
e) la collecte des particules en suspension dans l’air libérées dans la fraction massique des poussières alvéolaires pour des observations et une analyse supplémentaires par microscopie électronique.
NOTE 1 La plage granulométrique décrite ci-dessus a été établie sur la base de l’équipement utilisé au cours des recherches préalables à la normalisation [8].
Le présent document est applicable aux essais relatifs à une gamme étendue de matériaux en vrac, y compris des matériaux granulaires, en poudre ou sous forme de pastilles contenant ou émettant des NOAA ou autres particules en fraction alvéolaire sous formes revêtues, non revêtues, liées et non liées.
NOTE 2 Jusqu’à présent, aucun système de classification basé sur le nombre en termes de nombre de particules et de taux d’émission n’a été établi concernant l’aptitude à l’empoussièrement des poudres. Dès lors que des données de mesure seront disponibles en grand nombre, il est prévu de réviser le présent document et d’introduire un tel système de classification, le cas échéant.
NOTE 3 La méthode du petit tambour rotatif a été employée pour déterminer le pouvoir de resuspension d’une gamme de matériaux parmi lesquels des nanoparticules d’oxydes, des nanoflocons, des argiles organiques, des argiles, du noir de carbone, du graphite, des nanotubes de carbone, des pigments organiques et des ingrédients pharmaceutiques actifs. Ainsi, il s’est avéré que la méthode était appropriée pour les essais relatifs à un grand nombre de matériaux différents pouvant contenir des nanomatériaux en tant que composant principal.

Introduction
Dustiness measurement and characterization provide users (e.g. manufacturers, producers, occupational
hygienists and workers) with information on the potential for dust emissions when the bulk material is
handled or processed in workplaces. They provide the manufacturers of bulk materials containing NOAA
with information that can help to improve their products and reduce their dustiness. It allows the users
of the bulk materials containing NOAA to assess the controls and precautions required for handling and
working with the material and the effects of pre-treatment (e.g. modify surface properties or chemistry).
It also allows the users to select less dusty products, if available. The particle size distribution of the
aerosol and the morphology and chemical composition of its particles can be used by occupational
hygienists, scientists and regulators to further characterize the aerosol in terms of particle size
distribution and chemical composition and to thus aid users to evaluate and control the health risk of
airborne dust.
This document gives details on the design and operation of the small rotating drum method that can be
used to measure the dustiness of bulk materials that contain or release respirable NOAA or other
respirable particles in terms of dustiness indices or emission rates. Dustiness indices as well as particle
emission rates can be mass-based of the health-related respirable dustiness mass fraction using a cyclone
for the respirable dust fraction and by number using real-time sampling of particle number
concentrations. The particle size distribution of the released aerosol is measured using direct-reading
aerosol instruments. The released dust particles can be further sampled and characterized for, e.g.
physical size distribution, morphology and chemical composition by off-line analysis (as required).This
test uses the same dust generation principle as EN 15051-2 and EN 17199-2 [1], but the rotating drum
volume and diameter is smaller and the sampling design different, which allows testing of small sample
volumes and simultaneous sampling of all realtime data and dust for off-line analysis.
