Workplace atmospheres - Measurement of the dustiness of bulk materials - Requirements and reference test methods
This document specifies the two reference test apparatuses and reference test methods for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable, thoracic and respirable fractions of this dust, with reference to the existing CEN standards, where relevant (see Clause 6).
This document specifies the environmental conditions, the sample handling and analysis procedures and the method of calculating and presenting the results. A classification scheme for dustiness is specified, to provide a standardised way to express and communicate the results to users of the bulk materials.
In Annex D, a test method is described that enables dustiness information produced by test methods other than these two reference test methods to be related to that produced using these standard reference test methods.
This document is applicable to powdered, granular or pelletised materials. A standard sample volume is used.
This document is not applicable to test the dust released when solid materials are mechanically reduced (e.g. cut, crushed) or to test handling procedures for the materials.

Klassifikationssystem für das Staubungsverhalten festgelegt.
Anhang D beschreibt ein Prüfverfahren, das erlaubt, die Information zum Staubungsverhalten, die nach einem
anderen Verfahren als den beiden Referenzprüfverfahren ermittelt wurde, auf die Information zum
Staubungsverhalten zu beziehen, die nach einem der genormten Referenzprüfverfahren erhalten wurde.
Das vorliegende Dokument gilt für pulverförmige, granulierte oder pelletierte Materialien. Bei der
Prüfungsdurchführung wird ein genormtes Probenvolumen verwendet.
Dieses Dokument gilt nicht für die Prüfung von Staub, der bei der mechanischen Zerkleinerung fester
Materialien (z. B. beim Schneiden, Brechen) freigesetzt wird, oder um Verfahren zur Handhabung von
Schüttgütern zu prüfen.

Le présent document spécifie les deux appareillages et méthodes d’essai de référence à utiliser pour produire des poussières de manière reproductible, à l’aide de matériaux en vrac, dans des conditions normalisées, en vue de mesurer les fractions inhalable, thoracique et alvéolaire de ces poussières, en référence aux normes CEN existantes, s’il y a lieu (voir Article 6).
Le présent document spécifie également les conditions ambiantes, les méthodes de manipulation et d'analyse des échantillons ainsi que la méthode de calcul et d'expression des résultats. Une méthode de classification du pouvoir de resuspension est également spécifiée, afin de normaliser le mode d'expression et de communication des résultats aux utilisateurs des matériaux en vrac.
L’Annexe D décrit une méthode d’essai permettant de corréler les données relatives au pouvoir de resuspension obtenues à l'aide de méthodes d’essai autres que ces deux méthodes de référence avec les données obtenues à l'aide des méthodes de la présente norme.
Le présent document s’applique aux matériaux granulaires, en poudre ou sous forme de pastilles. Un volume étalon est utilisé.
Le présent document ne s’applique pas à la détermination de l’empoussièrement dû à la réduction mécanique (par exemple découpe, concassage) de matériaux solides ni à l’évaluation des méthodes de manipulation des matériaux.

It is advantageous, therefore, for occupational hygienists and process engineers to have accurate information about the propensity of materials to produce airborne dust (the ‘dustiness’ of the material) so that risks can be evaluated, controlled and minimised. No single method of dustiness testing is likely to represent and reproduce the various types of processing and handling used in industry. Therefore a number of dustiness testing methods are in use in different industries. Different methods use different test apparatus and measuring principles, and express results in different ways. Methods that do not separate the dust cloud produced into the three health-related size fractions - inhalable, thoracic and respirable dust - can serve the needs of manufacturing industry for process and batch control, but give limited information on the health hazard due to the dustiness of the material. Dustiness is a relative term and the measurement obtained will depend on the test apparatus used, the properties of the dust and various environmental variables. The test and the variables therefore need to be closely specified to ensure reproducibility. Recognising the above it was concluded that there was a need for standardised reference methods to measure the dustiness of bulk materials, based on the biologically relevant aerosol fractions defined in EN 481. This document establishes reference test methods that classify the dustiness, in terms of health-related fractions, of bulk solid materials. The dustiness classification is intended to provide users (e.g. manufacturers, producers, occupational hygienists and workers) with information on the potential for dust emissions when the material is handled or processed in workplaces. It provides the manufacturers of materials with information that can help to improve their products. It allows the users of the materials to assess the effects of pre-treatments, and also to select less dusty products, if available. Although this document does not discuss the analysis of dust released from bulk materials (except in terms of health-related fractions), the test method produces samples with the potential for chemical analysis of the contents. This document also provides reference test methods to which users of alternative test methods on dustiness can compare their own measurements. A standardised test of equivalence is used to test whether the alternative test method is capable of reproducing the dustiness classifications of the reference test methods, for a range of standardised test dusts. If the requirements for equivalence are satisfied the alternative test method can be used to classify the dustiness of bulk materials. This document was developed based on the results of the European project SMT4-CT96-2074 Development of a Method for Dustiness Testing (see [1]). This project investigated the dustiness of 12 materials, with the intention to test as wide a range of materials as possible, i.e. magnitude of dustiness, industrial sectors, chemical composition and particle size distribution.
