ICS 13.040 is a classification code in the International Classification for Standards (ICS) system. It covers "Air quality". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 2306 standards classified under ICS 13.040 (Air quality). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document specifies a sampling method to determine the quantity of formaldehyde (HCHO) in the air with the range of approximately 1 µg/m3 to 1 mg/m3 in a time-weighted average (TWA) sample, for long-term (1 h to 24 h) and short-term (5 min to 60 min) sampling. This method involves the collection of compounds from air on to adsorbent cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis of the hydrazones formed by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption [7] [8].
This document can also be applied for the determination of at least 12 other aromatic as well as saturated and unsaturated aliphatic carbonyl compounds (aldehydes and ketones), with modification, such as:
— acetaldehyde;
— acetone;
— benzaldehyde;
— butyraldehyde;
— capronaldehyde;
— 2,5-dimethylbenzaldehyde;
— formaldehyde;
— isovaleraldehyde;
— propionaldehyde;
— m-tolualdehyde;

This document defines and describes the methodology to calculate Modelling Quality Indicators (MQI) and determine fulfilment of the Modelling Quality Objectives (MQO). MQO are provided to help ensure that modelling-based assessments of air quality in the context of the ambient air quality directive [1] are objective and comparable, and of sufficient quality to obtain reliable information about concentrations of air pollutants in ambient air. The method uses measurement uncertainty and a level of stringency as a benchmark for the acceptable level of difference between modelled and measured values.
This document concerns the performance of an entire modelling system therefore the term “modelling quality objectives” is used rather than “model quality objectives”. This document concerns the use of modelling results for assessment as specified in [2]. Such modelling systems aim to capture both the spatial and temporal variability of the environmental indicator under assessment in the modelling domain. This document establishes a method to determine if the results of a modelling system fulfil the MQO and therefore reach an adequate data quality level within the modelling domain defined for assessment.
The procedures described in this document are limited in scope as they concern only statistical performance indicators. A full evaluation of a modelling system considers additional elements of quality assurance, but such procedures are outside the scope of this document.
This document only addresses modelling applications where measurements of pollutant concentrations are available that meet the data requirements for the validation defined in this document. This document specifies MQO that are applicable to all concentration ranges that may occur in ambient air. In the context of this document, MQI and MQO are specified for:
- daily and annual averaged concentrations of particulate matter with aerodynamic diameter less or equal to 2,5 µm (PM2.5);
- daily and annual averaged concentrations of particulate matter with aerodynamic diameter less or equal to 10 µm (PM10);
- hourly, daily and annual averaged concentrations of nitrogen dioxide (NO2);
- maximum daily 8-hour mean and seasonal averaged concentrations of ozone (O3);
- hourly, daily and annual averaged concentrations of sulphur dioxide (SO2);
- maximum daily 8-hour mean and daily averaged concentrations for carbon monoxide (CO);
- annual averaged concentrations for benzene (C6H6);
- annual averaged concentrations for lead (Pb);
- annual averaged concentrations for arsenic (As);
- annual averaged concentrations for cadmium (Cd);
- annual averaged concentrations for nickel (Ni);
- annual averaged concentrations for benzo[a]pyrene (BaP).
This document addresses competent authorities, research institutions, consultants, or other bodies responsible for the performance of air quality modelling when applied for assessment purposes.
NOTE Fulfilment of MQO is either normative or informative, depending on the quality of information used to determine the uncertainty parameters and stringency factors set out in this document.

This document specifies a test method for the sampling and analysis of airborne organic isocyanate (NCO) compounds in workplace air. The method covers organic compounds containing free isocyanate functional groups, including monomeric, oligomeric, prepolymeric and polymeric isocyanates, and addresses the measurement of total isocyanate groups in air samples collected for the assessment of occupational exposure.
The method is suitable for personal air sampling in the breathing zone for the determination of time-weighted average concentrations over sampling periods ranging from approximately 10 min to 8 h, although it can be applied to shorter sampling periods with high isocyanate air levels. It can also be used for background or fixed-location air sampling; however, due to aerodynamic effects, samplers designed for personal sampling do not necessarily exhibit the same collection characteristics when used for other purposes. It covers the measurement of airborne organic isocyanates over a concentration range of approximately 0,1 μg/m3 to 140 μg/m3 for a nominal air sample volume of 15 l; under the conditions specified in this document, typical qualitative and quantitative detection limits correspond to approximately 0,07 μg/m3 a nd 0 ,3 μg/m3, respectively, for a 15 l air sample.
This document does not apply to the simultaneous determination of isocyanates and amines, nor to modified methods employing alternative sampling devices or detection techniques not described in this document.

This document specifies a method for the determination of organic isocyanates in workplace air using derivatization with di-n-butylamine (DBA) and chromatographic analysis.
This document is applicable to the determination of a wide range of organic isocyanates present in both the gas phase and the particle phase in workplace atmospheres, including monofunctional isocyanates such as isocyanic acid (ICA), methyl isocyanate (MIC), ethyl isocyanate (EIC), propyl isocyanate (PIC), butyl isocyanate (BIC) and phenyl isocyanate (PhI); monomeric diisocyanates, including 1,6-hexamethylene diisocyanate (HDI), 2,4- and 2,6-toluene diisocyanate (TDI), 4,4′-methylenediphenyl diisocyanate (MDI), 1,5-naphthyl diisocyanate (NDI), isophorone diisocyanate (IPDI) and 4,4′-dicyclohexylmethane diisocyanate (H12MDI); and multifunctional isocyanates, including oligomeric, prepolymeric and polymeric forms such as biuret-, isocyanurate- and allophanate-adducts.
The method covers air sampling using impingers, filters or combinations thereof, and analysis by liquid chromatography with mass spectrometric detection.
The useful analytical range is approximately 2,5 ng to 500 ng of isocyanate per sample. For a nominal air sample volume of 15 l, this corresponds to approximately 0,2 µg/m3 to 33 µg/m3. These values can vary depending on the isocyanate analysed.
This document does not apply to the determination of amines or aminoisocyanates. For the determination of amines and aminoisocyanates, the method specified in ISO 17734-2[11].

This document specifies the determination of height-resolved profiles of atmospheric backscattering by means of active optical sounding. The measurements allow the following properties of the atmosphere up to several kilometres above ground to be derived:
cloud bases;
upper boundaries of optically thin clouds;
upper and lower boundaries and internal structures of particle layers:
height of structures, e.g. inversions, boundary layer height, mixing layer height (under suitable conditions);
attenuated backscatter of the particles;
particle backscatter and extinction coefficients (requires further assumptions).
The document also addresses the depolarisation lidar and the use of multi-wavelength systems. This allows further parameters to be determined:
particle size classification (Ångström exponent, colour ratio);
shape classification (linear depolarisation degree).
The following fields of application are particularly important:
air quality monitoring (vertical structure of the boundary layer);
aviation safety (cloud base and visual range) (see ISO 28902-1[8]);
particle content and transport (e.g. volcanic dust);
weather forecasting and climate modelling (e.g. atmospheric boundary layer, cloud base, cloud microphysics);
satellite remote sensing (validation).
Examples that illustrate these applications are discussed in Annex A.
The benefits of scanning systems for parameters mentioned above are also discussed in Clause A.7.
In addition, particle backscatter lidars that measure at least two carefully selected wavelengths can be used to determine atmospheric gas concentrations. This is known as the differential absorption lidar “DIAL” technique. This technique is not part of this document and has been described in VDI 4210-1[12].
This document does not specify extended lidar techniques that monitor the following parameters quantitatively: inelastic scattering effects such as, Raman scattering, Doppler broadening, Doppler shift, multiple scattering, modulation techniques, and spectral separation of molecular and particle backscattering [high spectral resolution lidar (HSRL)]. Some of these extended techniques are or will be described in other parts of the ISO 28902 series.
This document does not address special features of airborne or satellite-borne systems.

This document specifies procedures for quantification of asbestos mass fractions below approximately 5 %, and for quantitative determination of asbestos in vermiculite, other industrial minerals and commercial products that incorporate these minerals.
This document is applicable to the quantitative analysis of:
a) any material for which the estimate of asbestos mass fraction obtained using ISO 22262-1 is deemed to be of insufficient precision to reliably classify the regulatory status of the material (i.e. whether the material is subject to asbestos regulations in the particular jurisdiction) or for which it is considered necessary to obtain further evidence to demonstrate the absence of asbestos;
b) resilient floor tiles, asphaltic materials, roofing felts and any other materials in which asbestos is embedded in an organic matrix;
c) wall and ceiling plasters, with or without aggregate;
d) vermiculite and commercial products containing vermiculite;
e) mineral powders such as talc, wollastonite, sepiolite, attapulgite (palygorskite), calcite or dolomite, and commercial products containing these minerals.
This document primarily applies to samples in which asbestos has been identified at estimated mass fractions lower than approximately 5 % by sample mass. This document is also applicable to samples that can contain asbestos at low mass fractions incorporated into matrix material such that microscopical examination of the untreated sample is either not possible or unreliable.

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, 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 EN 17199 2 [1], EN 17199 3 [2] and EN 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 document gives guidance on the procedure for the bioaccumulation of substances liable to cause atmospheric pollution. This is done by using the grass species Lolium multiflorum ssp. italicum designated hereafter as Italian rye-grass. It is an active biomonitoring approach insofar as the plants used are first cultivated in set conditions before being exposed at the monitoring locations in the field. The plants then record any pollution events that occur while they are being exposed, allowing such events to be accurately dated.
The document specifies a method for identification and localization of one or more single pollution sources and the tracking of their "plume" on a local or regional scale. The method described also offers a tool to monitor sites in the long term by the repeated application of a clearly defined procedure and to describe the local or regional air pollution situation.
The method described in this document is applicable to solid and gaseous substances deposited on plants, where they can accumulate on their surface or in their tissues. These substances include sulphur, chloride, fluoride and especially metals as well as low volatile organic and halo-organic compounds such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), polybrominated diphenyl ethers (PBDE), polychlorinated dibenzo dioxins (PCDD) and polychlorinated dibenzo furans (PCDF). It is as well possible to verify pesticides which are used in plant protection products. The range of potential substances can be expanded according to the task at hand and the capabilities of conducting trace analyses and assessment.
The method described in this document allows spatial and temporal comparisons and allows for screening, thus providing a first indication of risk. The results of grass culture studies can suggest risks to biota (e.g. via the food chain) which require further investigation.
The method described in this document does not replace physico-chemical methods of direct measurement or modelling of air pollutants and cannot be replaced by them for its part; it complements them by indicating biological effects.
Potential areas of deployment are:
- permit procedures related to air pollution legislation;
- preservation of evidence related to the code for protection from pollution;
- monitoring of emission sources and performance control;
- assessment of local-scale emission transport;
- evidence of causation, e.g. related to environmental liability;
- air quality maintenance plans/strategies;
- long-term monitoring of ecological effects of atmospheric depositions;
- detection and assessment of local, regional, and countrywide effects of atmospheric depositions;
- assessment of risks for humans and/or animals via the food chain.
This document is of interest to those involved in environmental monitoring.

This document gives guidance on the procedure for the bioaccumulation of substances liable to cause atmospheric pollution. This is done by using the grass species Lolium multiflorum ssp. italicum designated hereafter as Italian rye-grass. It is an active biomonitoring approach insofar as the plants used are first cultivated in set conditions before being exposed at the monitoring locations in the field. The plants then record any pollution events that occur while they are being exposed, allowing such events to be accurately dated.
The document specifies a method for identification and localization of one or more single pollution sources and the tracking of their "plume" on a local or regional scale. The method described also offers a tool to monitor sites in the long term by the repeated application of a clearly defined procedure and to describe the local or regional air pollution situation.

This document 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 dustiness mass fractions, with reference to existing documents, 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 specified in this document. It differs from the rotating drum method presented in EN 15051-2 [4] in that in this document, the bulk material is dropped only once, but continuously, while in EN 15051-2, the same bulk material is repeatedly dropped.
Furthermore, this document specifies the environmental conditions, the sample handling and analytical procedures and the method of calculating and presenting the results. A categorization scheme for dustiness is specified, to provide a standardized way to express and communicate the results to users of the bulk materials.
This document is applicable to powdered, granular or pelletised bulk materials.

This document specifies procedures for quantification of asbestos mass fractions below approximately 5 %, and for quantitative determination of asbestos in vermiculite, other industrial minerals and commercial products that incorporate these minerals. This document is applicable to the quantitative analysis of: a) any material for which the estimate of asbestos mass fraction obtained using ISO 22262-1 is deemed to be of insufficient precision to reliably classify the regulatory status of the material (i.e. whether the material is subject to asbestos regulations in the particular jurisdiction) or for which it is considered necessary to obtain further evidence to demonstrate the absence of asbestos; b) resilient floor tiles, asphaltic materials, roofing felts and any other materials in which asbestos is embedded in an organic matrix; c) wall and ceiling plasters, with or without aggregate; d) vermiculite and commercial products containing vermiculite; e) mineral powders such as talc, wollastonite, sepiolite, attapulgite (palygorskite), calcite or dolomite, and commercial products containing these minerals. This document primarily applies to samples in which asbestos has been identified at estimated mass fractions lower than approximately 5 % by sample mass. This document is also applicable to samples that can contain asbestos at low mass fractions incorporated into matrix material such that microscopical examination of the untreated sample is either not possible or unreliable.

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, 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 EN 17199 2 [1], EN 17199 3 [2] and EN 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.
