Workplace exposure - Measurement of dustiness of bulk materials that contain or release respirable NOAA or other respirable particles - Part 2: Rotating drum method
This document provides the methodology for measuring 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 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, thoracic and inhalable dustiness mass fractions,
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 number-based emission rate of respirable particles in the particle size range from about 10 nm to about 1 µm,
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, and
e) the collection of released airborne particles in the respirable 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 [4].
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 dustiness indices or emission rates have been established. Eventually, when a large number of measurement data has been obtained, the intention is to revise this document and to introduce such a classification scheme, if applicable.
NOTE 3 The method specified in this document has not been investigated for the measurement of the dustiness of bulk materials containing nanofibres and nanoplates in terms of number-based dustiness indices or emission rates. However, there is no reason to believe that the number-based dustiness indices or emission rates could not be measured with the rotating drum method using the set-up described in this document.
Exposition am Arbeitsplatz - Messung des Staubungsverhaltens von Schüttgütern, die alveolengängige NOAA oder andere alveolengängige Partikel enthalten oder freisetzen - Teil 2: Verfahren mit rotierender Trommel
Diese Europäische Norm enthält die Methodik für die Messung 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 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 Messung des Massenanteils an alveolengängigem, thorakalem und einatembarem Staub,
b) die Messung des zahlenbasierten Staubindex alveolengängiger Partikel im Größenbereich zwischen ungefähr 10 nm und 1 000 nm,
c) die Messung der zahlenbasierten Emissionsrate alveolengängiger Partikel im Größenbereich zwischen ungefähr 10 nm und 1 000 nm,
d) die Messung der zahlenbasierten Größenverteilung des freigesetzten Aerosols im Größenbereich zwischen ungefähr 10 nm und 10 µm und
e) die Sammlung freigesetzter Schwebstoffe in der alveolengängigen Fraktion für anschließende Beobachtungen und Analysen durch analytische Elektronenmikroskopie.
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 im Hinblick auf Staubungsindizes oder Emissionsraten entwickelt. Schließlich, wenn eine große Anzahl an Messdaten vorliegt, ist beabsichtigt, diese Europäische Norm zu revidieren und ein solches Klassifizierungsschema einzuführen.
ANMERKUNG 2 Das in dieser Europäischen Norm festgelegte Verfahren wurde nicht für die Messung des Staubungsverhaltens von Schüttgütern mit Nanofasern und Nanoplättchen in Bezug auf die zahlenbasierten Staubungs-indizes oder Emissionsraten untersucht. Es besteht jedoch kein Grund zu der Annahme, dass die zahlenbasierten Staubungsindizes oder Emissionsraten nicht durch das Verfahren mit rotierender Trommel unter Verwendung des in dieser Europäischen Norm festgelegten Versuchsaufbaus gemessen werden 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 2: Méthode du tambour rotatif
Le présent document décrit la méthodologie permettant de mesurer 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 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 des fractions massiques des poussières alvéolaires, thoraciques et inhalables ;
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 d’émission en nombre de particules alvéolaires dans la plage granulométrique comprise entre environ 10 nm et 1 µm ;
d) le mesurage de la distribution granulométrique en nombre de particules d’aérosol libérées dans la plage granulométrique comprise entre environ 10 nm et 10 µm ;
e) la collecte des particules en suspension dans l’air dans la fraction alvéolaire 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 [4].
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 Aucun système de classification basé sur le nombre en termes d’indices de pouvoir de resuspension ou de taux d’émission n’a encore été établi. 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 spécifiée dans le présent document n’a pas été conçue pour le mesurage du pouvoir de resuspension des matériaux en vrac contenant des nanofibres et des nanofeuillets en fonction des indices de pouvoir de resuspension ou des taux d’émission en nombre. Toutefois, il n’y a aucune raison de penser que les indices de pouvoir de resuspension ou les taux d’émission en nombre ne peuvent pas être mesurés par la méthode du tambour rotatif utilisant le montage d’essai décrit dans le présent document.
Izpostavljenost na delovnem mestu - Meritve prašnosti razsutih materialov, ki vsebujejo ali sproščajo respirabilne nanopredmete ter njihove agregate in aglomerate (NOAA) in druge respirabilne delce - 2. del: Metoda z vrtečim bobnom
Ta evropski standard določa metodologijo za merjenje prašnosti razsutih materialov, ki vsebujejo ali sproščajo nanopredmete ali submikrometrske delce v standardnih in ponovljivih pogojih, ter za ta namen določa metodo z vrtečim bobnom.
Poleg tega navaja ta evropski standard tudi izbiro instrumentov in naprav ter postopke za izračun in predstavitev rezultatov. Podaja tudi smernice za vrednotenje in poročanje podatkov.
Metodologija, ki je opisana v tem evropskem standardu, omogoča:
a) merjenje masnih deležev pri respirabilni, torakalni in inhalabilni prašnosti,
b) merjenje indeksa prašnosti respirabilnih delcev na podlagi števila v razponu velikosti od približno 10 nm to 1000 nm,
c) merjenje stopnje emisij respirabilnih delcev na podlagi števila v razponu velikosti od približno 10 nm to 1000 nm,
d) merjenje porazdelitve velikosti sproščenega aerosola na podlagi števila v razponu velikosti od približno 10 nm to 10 µm,
e) zbiranje sproščenih lebdečih delcev v respirabilnih deležih za nadaljnje opazovanje in analizo z analitsko elektronsko mikroskopijo.
Ta evropski standard se uporablja za preskušanje širokega nabora razsutih materialov, vključno s praški, granulami in peleti, ki vsebujejo ali sproščajo nanopredmete ali submikrometrske delce v nevezani, vezani, prevlečeni ali neprevlečeni obliki.
OPOMBA 1: Za indekse prašnosti ali stopnje emisij trenutno še ni vzpostavljena nobena klasifikacijska shema na podlagi števil. Ko bo sčasoma pridobljenih veliko merilnih podatkov, je predvidena revizija tega evropskega standarda in uvedba take klasifikacijske sheme, če bo to ustrezno.
OPOMBA 2: Metoda, ki je navedena v tem evropskem standardu, še ni bila preiskana za merjenje prašnosti razsutih materialov, ki vsebujejo nanovlakna in nanoplošče v smislu indeksov prašnosti ali stopenj emisij na podlagi števil. Vendar ni razloga za domnevo, da indeksov prašnosti ali stopenj emisij ni mogoče izmeriti na podlagi števil z vrtečim bobnom in pripravo, opisano v tem evropskem standardu.

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 rotating drum method that measures 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 emission rates can be
number-based or mass-based. In addition, the test method characterizes the released aerosol by
measuring the particle size distribution using direct-reading aerosol instruments and collects samples
for off-line analysis (as required) for their morphology and chemical composition. This test uses the
same dust generation method as EN 15051-2. The determination of the health-related dustiness mass
fractions of the released dust from a bulk material containing NOAA is carried out according to
EN 15051-1 and EN 15051-2, an experimental set-up different from the one used to determine the
number-based dustiness index and the number-based emission rate.
The rotating drum method is useful for addressing the ability of bulk materials including nanomaterials
(in powder form), to release airborne particles (aerosol) during agitation, the so-called dustiness.
The rotating drum method has been designed to simulate workplace scenarios and to represent general
bulk material handling processes, including processes where bulk material is tipped, poured, mixed,
scooped, dropped or similar, either mechanically or by hand.
The rotating drum method presented here differs from the continuous drop, the small rotating drum
and the vortex shaker methods presented in EN 17199-3 [1], EN 17199-4 [2] and EN 17199-5 [3]
respectively. The rotating drum and small rotating drum methods perform, both, repeated pouring or
agitation of a bulk material. The continuous drop method simulates continuous feed of a bulk material
while the vortex shaker method simulates vig
