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;
— o-tolualdehyde;
— p-tolualdehyde;
— valeraldehyde.
This document does not apply to longer chained or unsaturated carbonyl compounds such as acrolein. An alternative sampling method using sorbent tubes and analysis by thermal desorption using gas chromatography with mass spectrometry (GC-MS) is given in Annex A.

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 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 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 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 specifies test methods which are intended to determine the fogging characteristics of polyvinyl chloride (PVC) or polyurethane textiles that are used as trim materials in the interior of motor vehicles. The methods can also be applied to fluid, paste, powdered or solid raw materials which are the basis for such trim materials or from which the materials are manufactured. The methods can also be applied to other materials and finished products. The procedures are applicable to the measurement of fog condensate on glass surfaces within the limits of the test conditions. These tests do not or cannot measure accurately those cases in which: — the surface tension of the condensate is low, resulting in early coalescing into a thin transparent film; — the condensate is present in such a large quantity that the droplets coalesce and form a heavy oily/clear film (this heavy film gives false readings). NOTE In such cases, the gravimetric method is used.

This document describes an analytical method to determine the emissions from non-metallic materials used for moulded parts in motor vehicles, such as textiles, carpets, adhesives, sealing compounds, forms, leather, plastic parts, films and sheets, paints or material combinations. The materials are characterized in terms of the type and quantity of organic substances that can be outgassed from them. For this purpose, two semiquantitative sum values are determined, which allow an estimation of the emissions of volatile organic compounds (VOC value) and the proportion of condensable substances [low volatile “fogging” compound (FOG) value]. Furthermore, individual substances of the emission are determined. During the analysis, the samples are thermally extracted, the emissions are separated by gas chromatography and detected by mass spectrometry. The test method presented in this document provides values that are valid only for conditions described in this document. The results which can be achieved using this method are not appropriate for making further estimations of any kind of the health effects of emitted substances nor should they be used might that can be found in the interior of a complete vehicle in stationary condition, while driving or in conditions similar to driving.

This document specifies a method for the sampling of NO2 in ambient air using diffusive sampling followed by extraction and analysis by colourimetry or ion chromatography (IC). It can be used for the NO2 measurement in a concentration range of approximately 3 µg/m3 to 130 µg/m3 [12]. A sample is typically collected for a period of 1 to 4 weeks [14], with exposure periods depending on the design of the samplers and the concentration levels of NO2.
Several sorbents can be used for trapping NO2 in ambient air using a diffusive sampler [15]. This document specifies the application of triethanolamine as the reagent.
This document describes the application of a tube-type sampler (with either a cylindrical or a slightly conical tube), a badge-type sampler and a radial-type sampler.
The relative expanded uncertainty of NO2 measurements performed using these tube-type diffusive samplers can potentially be lower than 25 % for individual measurements. When aggregating results to form annual average values, the relative expanded uncertainty can be further reduced to levels below 15 % due to the reduction of random effects on uncertainty [9].
NOTE NO2 passive samplers are also employed to measure NOx with the addition of an oxidant to convert ambient NO into NO2. A second NO2 sampler is also deployed without the oxidant and the concentration of NO is determined from the difference of the two samplers [16].

This document specifies the sampling and analysis of phthalates in indoor air and describes the sampling and analysis of phthalates in house dust and in solvent wipe samples of surfaces by means of gas chromatography-mass spectrometry (GC-MS).
Two alternative sampling, sample preparation and sample introduction methods, whose comparability has been proven in an interlaboratory test, are specified for indoor air[1]:
— sorbent tubes sampling with subsequent thermal desorption GC-MS, and
— sampling by adsorption and subsequent solvent extraction and injection to GC-MS.
Additional adsorbents that can be used are described in Annex B.
Depending on the sampling method, the compounds dimethyl phthalate to diisoundecylphthalate can be analysed in house dust as described in Annex D. The investigation of house dust samples is only appropriate as a screening method. This investigation only results in indicative values and is not acceptable for a final assessment of a potential need for action.
Dimethyl phthalate to diisoundecylphthalate can be analysed in solvent wipe samples as described in Annex C. Solvent wipe samples are suitable for non-quantitative source identification.
NOTE In principle, the method is also suitable for the analysis of other phthalates, adipates and cyclohexane dicarboxylic acid esters, but this is confirmed by determination of the performance characteristics in each case.
General information on phthalates are given in Annex A.

This document specifies the general principles, including testing procedures and requirements, for the classification of performance of low-cost sensor systems for the monitoring of particulate matter in ambient air at fixed sites. The classification of sensor systems includes tests that are performed under prescribed conditions. It does not guarantee performance in locations that are different from the tests, variations in meteorological climate from the test programme or account for stability over time, which can only be assessed under ongoing quality control strategies.
The described procedure is applicable to the determination of the mass concentration of particulate matter. The pollutants that are considered in this document are PM10 and PM2,5 in the range of concentrations expected in ambient air.
This document provides a classification that is consistent with the requirements for indicative measurements and objective estimation defined in Directive 2008/50/EC. In addition, it provides a classification for applications (non-regulatory measurements) that require more relaxed performance criteria.
This document applies to sensor systems used as individual systems. It does not apply to sensor systems as part of a sensor network. However, for some applications (e.g. in cities) sensor systems are deployed as part of a sensor network. Annex A provides information on the use of sensor systems as nodes in a sensor network.

This document specifies a process for the electrical diffusion charging of aerosols with subsequent measurement of particle charge. With the aid of this method, it is possible to determine the lung-deposited surface area (LDSA) concentration of particles in ambient air. Depending on the design of the electrical diffusion charger, the LDSA of particles in the size range of approximately 20 nm to approximately 300 nm is measurable.
Furthermore, this document specifies design criteria for LDSA measuring aerosol monitors as well as performance criteria and the associated test procedures. The performance criteria depend on the application and they are more stringent when the instrument is operated in an air quality monitoring station.
In the determination of the LDSA concentration, the share of geometric particle surface area concentration is determined that can be deposited in the alveolar region of the human lung. Typical particle surface area concentrations with alveolar deposition measured in urban areas range from 5 µm2/cm3 to 50 µm2/cm3.
Instruments based on this measurement principle can be designed to be very compact with a low power consumption. This makes them ideally suited for handheld measurements, other forms of mobile application or to measure personal exposure. On the other hand, they can be easily adapted to serve as a stationary instrument in air quality monitoring stations.
