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 vortex shaker 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 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 respirable aerosol in the particle size range from about 10 nm to 10 µm,
e)   the collection of released airborne particles in the respirable fraction for subsequent observations and analysis by electron microscopy.
This document is applicable to the testing of a wide range of bulk materials including nanomaterials in powder form.
NOTE 1    With slightly different configurations of the method specified in this document, dustiness of a series of carbon nanotubes has been investigated ([5] to [10]). On the basis of this published work, it can be assumed that the vortex shaker method is also applicable to nanofibres and nanoplates.
This document is not applicable to millimetre-sized granules or pellets containing nano-objects in either unbound, bound uncoated and coated forms.
NOTE 2   The restrictions with regard to the application of the vortex shaker method on different kinds of nanomaterials result from the configuration of the vortex shaker apparatus as well as from the small size of the test sample required. Eventually, if future work will be able to provide accurate and repeatable data demonstrating that an extension of the method applicability is possible, the intention is to revise this document and to introduce further cases of method application.
NOTE 3   As observed in the pre-normative research project [4], the vortex shaker method specified in this document provides a more energetic aerosolization than the rotating drum, the continuous drop and the small rotating drum methods specified in FprEN 17199 2 [1], FprEN 17199 3 [2] and FprEN 17199 4 [3], respectively. The vortex shaker method can better simulate high energy dust dispersion operations or processes where vibration or shaking is applied or even describe a worst case scenario in a workplace, including the (non-recommended) practice of cleaning contaminated worker coveralls and dry work surfaces with compressed air.
NOTE 4   Currently no classification scheme in terms of dustiness indices or emission rates has been established according to the vortex shaker method. 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.

This European Standard specifies the use of different metrics for the measurement of exposure by inhalation of NOAA during a basic assessment and a comprehensive assessment, respectively, as described in EN 17058 [1].
This document demonstrates the implications of choice of particle metric to express the exposure by inhalation to airborne NOAA, e.g. released from nanomaterials  and present the principles of operation, advantages and disadvantages of various techniques that measure the different aerosol metrics.
Potential problems and limitations are described and need to be addressed when occupational exposure limit values might be adopted in the future and compliance measurements will be carried out.
Specific information is mainly given for the following metrics/measurement techniques:
-   Number/Condensation Particle Counters by optical detection;
-   Number size distribution/differential mobility analysing systems by electrical mobility;
-   Surface area/electrical charge on available particle surface;
-   Mass/chemical analyses (e.g. Inductively Coupled Plasma atomic Mass Spectrometry (ICP-MS), X-Ray Fluorescence (XRF)) on size-selective samples (e.g. by impaction or diffusion).

This European Standard specifies the rotating drum test apparatus and associated test method 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 existing European Standards, where relevant (see Clause 6).
This method is suitable for general bulk material handling processes, including all those processes where the bulk material is dropped, or can be dropped. It differs from the continuous drop method presented in EN 15051 3 in this European Standard, the same bulk material is repeatedly dropped, while in EN 15051 3, the bulk material is dropped only once, but continuously.
Furthermore, this European Standard specifies the environmental conditions, the sample handling and analytical 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.
This European Standard is applicable to powdered, granular or pelletised bulk materials. A standard sample volume is used.
This European Standard is not applicable to test the dust released when solid bulk materials are mechanically reduced (e.g. cut, crushed) or to evaluate handling procedures for the bulk materials.

These performance requirements, which include conformity with the EN 481 sampling conventions, are applicable only to the process of sampling the airborne particles from the air, not to the process of analysing particles collected by the process of sampling. Although analysis of samples collected in the course of testing is usually necessary in order to evaluate the sampler performance, the specified test methods ensure that analytical errors are kept very low during testing and do not contribute significantly to the end result.
This part of EN 13205 specifies how the performance of aerosol measuring procedures is assessed with respect to the general requirements of EN 482, through the combination of errors arising in the sampling, sample transportation/storage and sample preparation/analysis stages.
This part of EN 13205 is applicable to all samplers used for the health-related sampling of particles in workplace air.
This part of EN 13205 is not applicable to the determination of analytical errors and factors related to them (for example the bias, precision and limit of detection of the analytical method). Where the aerosol sampler requires the use of an external (rather than integral) pump, the pump is not subject to the requirements of this part of EN 13205.

This European Standard specifies the continuous drop test apparatus and associated test method for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable and respirable fractions of this dust, with reference to existing European Standards, where relevant (see Clause 6).
The continuous drop method intends to simulate dust generation processes where there are continuous falling operations (conveying, discharging, filling, refilling, weighing, sacking, metering, loading, unloading etc.) and where dust is liberated by winnowing during falling. It can be modified to measure the thoracic fraction as well, but this modification is not described in this European Standard. It differs from the rotating drum method presented in EN 15051 2 in that in this European Standard, the bulk material is dropped only once, but continuously, while in EN 15051 2, the same bulk material is repeatedly dropped.
Furthermore, this European Standard specifies the environmental conditions, the sample handling and analytical 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.
This European Standard is applicable to powdered, granular or pelletised bulk materials.
This European Standard is not applicable to test the dust released when solid bulk materials are mechanically treated (e.g. cut, crushed) or to evaluate handling procedures for the bulk materials.

This Technical Report describes the use of photometers for the determination of airborne particles belonging to the respirable fraction and gives details on their limitations and possible uses in the field of occupational hygiene.
NOTE   Photometers can also be used to detect other size fractions of airborne particles after aerodynamic pre-separation, but these are not the focus of this Technical Report.
The method complements existing conventional long-term aerosol particle sampling and can be used for:
-   instantaneous (direct-reading) measurement,
-   time-related monitoring,
-   investigation of space-related aerosol evolution (mapping), and
-   exposure visualization.
The method enables e.g.:
-   detection and relative quantification of concentration peaks due to specific operations (bagging, sanding, etc.);
-   identification of most exposed workers with a view to more detailed studies of risks and prevention measures to be applied; and
-   detection of dust emission sources and their relative magnitudes.

ISO 13138:2012 specifies sampling conventions to define idealized samplers for estimating the deposition of non-volatile, non-hygroscopic, non-fibrous aerosols in five specific loci of the respiratory tract. The five loci consist of the anterior and posterior areas of the nasal passages, the ciliated and non-ciliated parts of the tracheobronchial area, and the alveolar (gas exchange) region.
The conventions are separated into three independent sampling efficiencies defined in terms of thermodynamic diameter characterizing the diffusive (Brownian) motion of sub-micrometre particles and four efficiencies in terms of aerodynamic diameter 0,1 μm characterizing deposition by impaction, interception or gravitational settling. Each conventional curve has been developed as an average of 12 deposition curves corresponding to 12 breathing conditions ranging from sitting to heavy exercise, male vs female, and breathing mode (mouth vs nasal breathing).

ISO 28439:2011 provides guidelines for the determination of the number concentration and size distribution of ultrafine aerosols and nanoaerosols by use of mobility particle sizers (also called differential mobility analysers). Only the particle fraction of the aerosol is considered. For ultrafine aerosols and nanoaerosols, exposure metrics such as the number and surface area concentration are important.
ISO 28439:2011 also gives guidelines for the determination of workplace exposure to ultrafine aerosols and nanoaerosols.
Specifically, the differential mobility analysing system (DMAS), now available from several vendors, is discussed. Principles of operation, problems of sampling in the workplace environment, calibration, equipment maintenance, measurement uncertainty, and reporting of measurement results are covered.
Potential problems and limitations are described, which need to be addressed when limit values are fixed and compliance measurements carried out.

This Technical Report describes the principle underlying evaluation of one or more health related aerosol fractions using an optical particle counter and details its limits and possibilities in the field of occupational hygiene.
The method complements conventional long-term aerosol particle sampling and offers possibilities of:
-   instantaneous (direct reading) measurement;
-   time-related monitoring;
-   investigation of space-related aerosol evolution (mapping);
-   assessment of particle size distribution.
The method enables e.g.:
-   detection and relative quantification of concentration peaks due to specific operations (bagging, sanding, etc.);
-   identification of most exposed workers with a view to more detailed studies of risks and prevention measures to be applied;
-   detection of dust emission sources and their relative magnitudes.
Basically, OPCs count airborne particles and are therefore suitable for measuring concentrations expressed in number of particles per unit volume of air. The applicability of the method is limited by the particle size and concentration ranges of OPC instruments, usually approximately 10-1 µm to 101 µm and 100 particles/cm3 to 103 particles/cm3, respectively.
Depending on specific conditions, the OPC method allows filter collection of an aerosol fraction, in the best case close to a health-related fraction (see EN 481), provided the OPC has the relevant sampling efficiency over its optical particle size range. If this is not the case, at least a sufficient aspiration efficiency is required to cover the size range of particles which can be detected and measured by the OPC optical system.
Converting count-based particle number concentrations into mass concentrations based on estimated particle size is indirect and therefore the accuracy of the conversion is limited by several simplifying assumptions:
-   identical optical parameters for both the calibration aerosol and the measured workplace aerosol;
-   (...)

These performance requirements, which include conformity with the EN 481 sampling conventions, apply only to the process of sampling the airborne particles from the air, not to the process of analysing particles collected by the process of sampling. Although analysis of samples collected in the course of testing is usually necessary in order to evaluate the sampler performance, the specified test methods ensure that analytical errors are kept very low during testing and do not contribute significantly to the end result. The determination of analytical errors and factors related to them (for example the bias, precision and limit of detection of the analytical method) is outside the scope of this standard. Where the aerosol sampler requires the use of an external (rather than integral) pump, the pump is not subject to the requirements of this standard.
EN 482 contains general performance requirements for methods used for determining the concentrations of chemical agents in workplace atmospheres. These performance requirements include maximum values of expanded uncertainty (a combination of random and non-random measurement uncertainty) achievable under prescribed laboratory conditions for the methods to be used. The requirements of EN 482 apply to a complete measurement procedure, a combination of the stages consisting of sampling, sample transport/storage and sample preparation/analysis. This standard specifies how the performance of aerosol measurement procedures is assessed with respect to the general requirements of EN 482, through the combination of errors arising in the sampling, sample transportation/storage and sample preparation/analysis stages.
