This International Standard provides the chemical analyzers with a method for evaluation of the measurement uncertainty arising when an impurity content of uranium solution is determined by a regression line that has been fitted by the "method of least squares".

Simple linear regression, hereinafter called "basic regression", is defined as a model with a single independent variable that is applied to fit a regression line through n different data points (xi, yi) (i = 1,…, n) in such a way that makes the sum of squared errors, i.e. the squared vertical distances between the data points and the fitted line, as small as possible. For the linear calibration, "classical regression" or "inverse regression" is usually used; however, they are inconvenient to use. Instead, "reversed inverse regression" is used in this International Standard[1].

Reversed inverse regression treats y (the reference solutions) as the response and x (the observed measurements) as the inputs; these values are used to fit a regression line of y on x by the method of least squares. This regression is distinguished from basic regression in that the xi’s (i = 1,…, n) vary according to normal distributions but the yi’s (i = 1,…, n) are fixed; in basic regression, the yi’s vary but the xi’s are fixed.

The regression line fitting, calculation of combined uncertainty, calculation of effective degrees of freedom, calculation of expanded uncertainty, reflection of reference solutions’ uncertainties in the evaluation result, and bias correction are explained in order of mention. Annex A presents a practical example of uncertainty evaluation. Annex B provides a flowchart showing the steps for uncertainty evaluation. In addition, Annex C explains the use of weighting factors for handling non-uniform variances in reversed inverse regression.

NOTE 1 In the case of classical regression, the fitted regression line must be inverted prior to actual sample measurement[2]. In the case of inverse regression, the roles of x and y are not consistent with the convention that the variable x represents the inputs, whereas the variable y represents the response. For these reasons, the two regressions are excluded from this International Standard.

NOTE 2 The term "reversed inverse regression" was suggested taking into account the history of regression analysis theory. Instead, it may be desirable to use some other term, e.g. "pseudo-basic regression".

This European Standard provides the methodology for measuring and characterizing the dustiness of a bulk material that contains or releases nano-objects or submicrometer particles. In addition, it specifies the environmental conditions, the sample handling procedure and the method of calculating and presenting the results. Guidance is given on the choice of method to be used.

The methodology described in this European Standard enables

a) the quantification of dustiness in terms of health-related index mass fractions,

b) the quantification of dustiness in terms of an index number and an emission rate, and

c) the characterization of the aerosol from its particle size distribution and the morphology and chemical composition of its particles.

NOTE 1 Currently, no number-based classification scheme in terms of particle number has been established for particle dustiness release. Eventually, when a large enough number of measurement data has been obtained, the intention is to revise this European Standard and to introduce a number-based classification scheme.

This European Standard is applicable to all bulk materials, including powders, granules or pellets, containing or releasing nano-objects or submicrometer particles.

NOTE 2 The vortex shaker method specified in part 5 of this European Standard has not yet been evaluated for pellets and granules.

NOTE 3 The rotating drum and continuous drop methods have not yet been evaluated for nanofibres and nanoplates.

This European Standard does not provide methods for assessing the release of particles during handling or mechanical reduction of machining (e.g. crushing, cutting, sanding, sawing) of solid nanomaterials (e.g. nanocomposites).

This European Standard provides the methodology for measuring the dustiness of bulk materials that contain or release nano-objects or submicrometer particles, under standard and reproducible conditions and specifies for that purpose the rotating drum method.

In addition, this European Standard 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 European Standard 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 size range from about 10 nm to 1 000 nm,

c) the measurement of the number-based emission rate of respirable particles in the size range from about 10 nm to 1 000 nm,

d) the measurement of the number-based size distribution of the released aerosol in the size range from about 10 nm to 10 μm, and

This European Standard provides the methodology for measuring and characterizing the dustiness of bulk materials that contain or release nano-objects or submicrometer particles, under standard and reproducible conditions and specifies for that purpose the vortex shaker method.

In addition, this European Standard 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 European Standard enables

a) the measurement of the respirable dustiness mass fraction,

b) the determination of the mass-based dustiness index of respirable particles in the size range from about 10 nm to 1 000 nm;

c) the determination of the number-based dustiness index of respirable particles in the size range from about 10 nm to 1 000 nm;

d) the determination of the number-based emission rate of respirable particles in the size range from about 10 nm to 1 000 nm;

e) the determination of the number size distribution of the released respirable aerosol in the size range from about 10 nm to 10 μm;

f) the collection of released airborne particles in the respirable fraction for subsequent observations and analysis by electron microscopy.

This European Standard 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 European Standard, 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 European Standard is not applicable to millimetre-sized granules or pellets containing nano-objects in either unbound, bound uncoated and coated forms.

NOTE 2 This comes from the configuration of the vortex shaker apparatus and the small test sample required. Eventually, if future work provides accurate and repeatable data demonstrating that this is possible, the intention is to revise the European Standard and to introduce this application.

NOTE 3 As observed in the pre-normative research Project [4], the vortex shaker method specified in this European Standard provides a more energetic aerosolization than the rotating drum, the continuous drop and the small rotating drum specified in prEN 17199-2:2017 [1], prEN 17199-3:2017 [2] and prEN 17199-4:2017 [3], respectively. It can better simulate high energy dust dispersion operations or processes where vibration 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 te vortex shaker method. Eventually, when a large number of measurement data has been obtained, the intention is to revise the European Standard and to introduce such a classification scheme, if applicable.
