This document specifies a determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones) in air. The method is specific to formaldehyde but, with modification, at least 12 other aromatic as well as saturated and unsaturated aliphatic carbonyl compounds can be detected and quantified. It is suitable for determination of formaldehyde and other carbonyl compounds in the approximate concentration range 1 µg/m3 to 1 mg/m3. The sampling method gives a time-weighted average (TWA) sample. It can be used for long-term (1 h to 24 h) or short-term (5 min to 60 min) sampling of air for formaldehyde.
This document specifies a sampling and analysis procedure for formaldehyde and other carbonyl compounds that involves collection 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[12],[16]. The method is not suitable for longer chained or unsaturated carbonyl compounds.

This European Standard describes a standard method for determining the PM10 or PM2,5 mass concentrations of suspendedparticulate matter in ambient air by sampling the particulate matter on filters and weighing them by means of a balance.
Measurements are performed with samplers with inlet designs as specified in Annex A, operating at a nominal flow rate of 2,3 m3/h,over a nominal sampling period of 24 h. Measurement results are expressed in μg/m3, where the volume of air is the volume atambient conditions near the inlet at the time of sampling.
The range of application of this European Standard is for 24 h measurements from approximately 1 μg/m3 (i.e. the limit of detection ofthe standard measurement method expressed as its uncertainty) up to 150 μg/m3 for PM10 and 120 μg/m3 for PM2,5.
This European Standard describes procedures and gives requirements for the testing and use of so-called sequential samplers,equipped with a filter changer, suitable for extended stand-alone operation. Sequential samplers are commonly used throughout theEuropean Union for the measurement of concentrations in ambient air of PM10 or PM2,5. However, this European Standard does notexclude the use of single-filter samplers.
This European Standard represents an evolution of earlier European Standards (EN 12341:1998 and 2014, EN 14907:2005). Newequipment procured shall comply fully with this European Standard.
Older versions of these samplers, including those described in EN 12341:2014 Annex B, have a special status in terms of their use. These samplers can still be used for monitoring purposes and for ongoing quality control, provided that a well justified additionalallowance is made to their uncertainties
This European Standard also provides guidance for the selection and testing of filters with the aim of reducing the measurementuncertainty of the results obtained when applying this European Standard.

This document specifies the measurement methods and strategies for determining the total number of airborne particles per unit volume of air indoor, using a condensation particle counter (CPC) for particles approximately between 10 nm to 3 µm. NOTE As the particle number concentration is usually dominated by the ultrafine particle (UFP) fraction, the obtained result can be used as an approximation of the UFP concentration. Quality assurance, determination of the measurement uncertainty and minimal reporting information are also discussed in this document. This document is applicable to indoor environments as specified in ISO 16000-1. This document does not address the determination of bioaerosols or the chemical characterization of particles. Nevertheless, some bioaerosols can be detected by the CPC and then contribute to the measured count of particles.

This document specifies a procedure for the assessment of the indoor air quality that is valid for all interior rooms in residential and non-residential buildings with natural or mechanical ventilation, in which people do not only stay temporarily. This document is applicable to indoor environments as defined in ISO 16000-1. The assessment of working materials in workrooms or workplaces in buildings, that are subject to statutory occupational safety specifications, are excluded from this document. In these rooms, only air constituents that do not originate from working materials can be assessed according to this document. It is not possible to define classes with exact values for the individual pollutants, as the corresponding limit and guide values differ in individual countries. In addition, the values relate to different observation periods. Aspects concerning electromagnetic fields, noise and vibrations and their effect on the indoor air quality are not the object of this document. The classification of further consequences and measures, such as organisational steps, structural engineering measures, renovation proposals, further human medicine appraisals and the like, are not the object of this document. NOTE This document applies to of all types of indoor environments occupied by all kinds of persons, including regular users, clients and workers.

This document specifies a method for determination of volatile organic compounds (VOC) in indoor air and in air sampled for the determination of the emission from products or materials used in indoor environments (according to ISO 16000‑1) using test chambers and test cells. The method uses sorbent sampling tubes with subsequent thermal desorption (TD) and gas chromatographic (GC) analysis employing a capillary column and a mass spectrometric (MS) detector with or without an additional flame ionisation detector (FID)[13].
The method is applicable to the measurement of most GC-compatible vapour-phase organic compounds at concentrations ranging from micrograms per cubic metre to several milligrams per cubic metre. Many very volatile organic compounds (VVOC) and semi-volatile organic compounds (SVOC) can be analysed depending on the sorbents used.

This document specifies the whole vehicle test chamber, the vapour sampling assembly and the operating conditions for the determination of volatile organic compounds (VOCs), and carbonyl compounds in vehicle cabin air. There are three measurements performed: one (for VOCs and carbonyl compounds) during the simulation of ambient conditions (ambient mode) at standard conditions of 23 °C - 25 °C with no air exchange; a second only for the measurement of formaldehyde at elevated temperatures (parking mode); and a third for VOCs and carbonyl compounds simulating driving after the vehicle has been parked in the sun starting at elevated temperatures (driving mode). For the simulation of the mean sun irradiation, a fixed irradiation in the whole vehicle test chamber is employed.
The VOC method is valid for measurement of non-polar and slightly polar VOCs in a concentration range of sub-micrograms per cubic metre up to several milligrams per cubic metre. Using the principles specified in this method, some semi-volatile organic compounds (SVOC) can also be analysed. Compatible compounds are those which can be trapped and released from the Tenax TA®[1] sorbent tubes described in ISO 16000‑6, which includes VOCs ranging in volatility from n-C6 to n-C16.
The sampling and analysis procedure for formaldehyde and other carbonyl compounds is performed by collecting air on to cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption. Formaldehyde and other carbonyl compounds can be determined in the approximate concentration range 1 µg/m3 to 1 mg/m3.
The method is valid for passenger cars, as defined in ECE-TRANS-WP.29/1045.
This document gives guidelines for:
a) transport and storage of the test vehicles until the start of the test;
b) conditioning for the surroundings of the test vehicle and the test vehicle itself as well as the whole vehicle test chamber;
c) conditioning of the test vehicle prior to measurements;
d) simulation of ambient air conditions (ambient mode);
e) formaldehyde sampling at elevated temperatures (parking mode);
f) simulation of driving after the test vehicle has been parked in the sun (driving mode).

This document describes a procedure for measuring the performance of general ventilation air cleaning
devices in their end use installed configuration. The performance measurements include removal
efficiency by particle size and the resistance to airflow. The test procedures include the definition and
reporting of the system airflow.
The procedure describes a method of counting ambient air particles of 0,3 μm to 5,0 μm upstream and
downstream of the in-place air cleaner(s) in a functioning air handling system. The procedure describes
the reduction of particle counter data to calculate removal efficiency by particle size.
Since filter installations vary dramatically in design and shape, a protocol for evaluating the suitability
of a site for filter evaluation and for system evaluation is included. When the evaluated site conditions
meet the minimum criteria established for system evaluation, the performance evaluation of the system
can also be performed according to this procedure.
This document also describes performance specifications for the testing equipment and defines
procedures for calculating and reporting the results. This document is not intended for measuring
performance of portable or movable room air cleaners or for evaluation of filter installations with an
expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 μm.

This document specifies a method for assessing the performance of photocatalytic inorganic materials contained in cement mortars and/or limes or ceramic-based matrices, paints or materials deposited as thin films or coatings on a variety of substrates for the photocatalytic abatement of nitric oxide in the gas phase. This method does not apply to the assessment of samples to be applied with flow perpendicular to the surface or flow permeating the surface itself as polymeric and paper filters, honeycomb structures and suchlike.
The performance for the photocatalytic sample under test is evaluated by measuring the degradation rate of nitric oxide (NO) using the method specified herein. The photocatalytic abatement rate is calculated from the observed rate by eliminating the effects of mass transfer. The intrinsic photocatalytic abatement rate is an intrinsic property of the material tested and makes it possible to distinguish the photocatalytic activities of various products with an absolute scale defined with physical and engineering meaning.
For the measurements and calculations described in this document the concentration of nitrogen oxides (NOx) is defined as the stoichiometric sum of nitric oxide (NO) and nitrogen dioxide (NO2).

This Technical Specification (TS) describes the general principles, including testing procedures and requirements, for the evaluation of performances of low-cost sensor systems for the monitoring of gaseous compounds in ambient air at fixed sites. The evaluation of sensor systems includes tests that shall be performed under prescribed laboratory and/or field conditions.
This TS is not intended for the test of sensors systems used for mobile devices, for the testing of networks of sensor nodes, or for indoor air monitoring although their potential importance is recognized and they could be the subjects of future TS documents.
Low-cost sensors are based on several principles of operations, e. g. amperometric sensors, metal oxides, optical sensors (Infra-Red absorption) etc. However, sensors share some common features, regarding their portability and low-cost compared to traditional reference methods. Typically, sensors are able to continuously monitor air pollution, with low response time ranging between a few tens of seconds and a few minutes.
The described procedure is applicable to the determination of the mass concentration of air pollutants. The pollutants that are considered in this TS consists of:
-the gaseous pollutants regulated under Directives 2008/50/EC: O3, NO2 and NO, CO, SO2 and benzene, in the range of concentrations expected in outdoor ambient air;
-CO2 as proxy for activities involving combustion processes or for CO2 evaporation from soil or water.
When applying the current Technical Specifications, the evaluation of sensors considers the thresholds, limits and averaging times that are defined into the Air Quality Directive (2008/50/EC)[1]. Generally, the Directive sets Limit Values consists of an annual average that is computed by averaging hourly values. For sensors, it can be useful to select shorter averaging time.
In order to rely on the results of tests this protocol, future users shall make sure that sensors will be implemented with the same configuration as the sensor submitted to this protocol. This can include: the same power supply, data acquisition, data processing, identical sampling/ protective box and periodicity of calibration. The sensor shall be submitted to the same regime of QA/QC and maintenance operation as during tests. In addition, it is strongly recommended that sensors measurements are periodically compared side-by-side with the reference method.
For the purpose of this technical specification sensor systems are significantly less expensive than reference methods for the same pollutant.

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 gaseous compounds in ambient air at fixed sites. The classification of sensor systems includes tests that are performed under prescribed laboratory and field conditions.
The procedure described is applicable to the determination of the mass concentration of air pollutants. The pollutants that are considered in this document are the gaseous pollutants regulated under Directive 2008/50/EC (O3, NO/NO2/NOx, CO, SO2 and benzene) 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 gives information on the use of sensor systems as nodes in a sensor network.
This document gives guidance on the testing of CO2 sensor systems in Annex B since, although not listed in Directive 2008/50/EC, CO2 is an interesting indicator as proxy for activities involving combustion processes or for CO2 evaporation from soil or water.

There are three measurements performed: one (for VOCs and carbonyl compounds) during the simulation of ambient conditions (ambient mode) at standard conditions of 23 °C with no air exchange; a second only for the measurement of formaldehyde at elevated temperatures (parking mode); and a third for VOCs and carbonyl compounds simulating driving after the vehicle has been parked in the sun starting at elevated temperatures (driving mode). For the simulation of the mean sun irradiation, fixed irradiation in the whole vehicle test chamber is employed. The VOC method is valid for measurement of non-polar and slightly polar VOCs in a concentration range of sub-micrograms per cubic metre up to several milligrams per cubic metre. Using the principles described in this method, some semi-volatile organic compounds (SVOC) can also be analysed. Compatible compounds are those which can be trapped and released from the Tenax TA®1) sorbent tubes described in ISO 16000‑6, which includes VOCs ranging in volatility from n-C6 to n-C16. The sampling and analysis procedure for formaldehyde and other carbonyl compounds is performed by collecting air on to cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption. Formaldehyde and other carbonyl compounds can be determined in the approximate concentration range 1 μg/m3 to 1 mg/m3. This method applicable to trucks and buses, as defined in ISO 3833:1977 3.1.1 to 3.1.6. This document describes: a) Transport and storage of the test vehicle until the start of the test. b) Conditioning of the surroundings of the test vehicle and the test vehicle itself as well as the whole vehicle test chamber. c) Conditioning of the test vehicle prior to measurements. d) Simulation of ambient air conditions (ambient mode). e) Formaldehyde sampling at elevated temperatures (parking mode). f) Simulation of driving after the test vehicle has been parked in the sun (driving mode). 1)Tenax TA® is the trade name of a product supplied by Buchem. This information is given for the convenience of users of this document and does not constitute an endorsement by ISO of the product named. Equivalent products may be used if they can be shown to lead to the same results.

This document contains specifications for active sampling of bioaerosols from exhaust air flowing through a defined cross-section of a stack. It defines general principles that have to be taken into account during an isokinetic sampling campaign for bioaerosols by bubbling the exhaust air through a specific impinger designed for emission measurements.
In this document the application with culturable organisms is specified but the same principle might be applicable for non-cultural based methods (e.g. molecular and/or enzyme-based methods).
The impinger is designed to allow a sample volume flow of 1 m3/h to 1,8 m3/h, or 16 l/min to 30 l/min, respectively, and has been tested with regard to various microorganisms within broad concentration ranges [1; 2; 3; 4]

The European Air Quality Directive (Directive on ambient air quality and cleaner air for Europe) identifies different uses for modelling: Assessment, planning, forecast and source apportionment (SA). This CEN/TS addresses source apportionment modelling and specifies performance tests to check whether given criteria for receptor oriented source apportionment (RM) are met. The scope of the tests set out in this CEN/TS is performance assessment of SA of particulate matter using RM in the context of the European Directives 2004/107/EC and 2008/50/EC (AQD) including the Commission Implementing Decision 2011/850/EU of 12 December 2011. The application of RM does not quantify the spatial origin of particulate matter hence this CEN/TS does not test spatial SA.
This CEN/TS addresses RM users: participants and organisers of source apportionment intercomparison studies as well as practitioners of individual source apportionment studies. This CEN/TS is suitable for the evaluation of results of a specific SA modelling system with respect to intercomparison reference values (a-priori known or calculated on the basis of participants' values, see 3.12) in the following application areas:
- Assessment of performance and uncertainties of a modelling system or modelling system set up using the indicators laid down in this CEN/TS.
- Testing and comparing different source apportionment outputs in a specific situation (applying an evaluation dataset) using the indicators laid down in this CEN/TS.
- QA/QC tests every time practitioners run a modelling system.
It should be noted for clarity that the procedures and calculations presented in this CEN/TS cannot be used to check the performance of a specific SA modelling result without having any a-priori reference information about the contributions of sources/source categories.
The principles of receptor oriented models are summarised in Annex A. An overview of uncertainty sources and recommendations about steps to follow in SA studies are provided in Annex B and Annex C.
There are different methodologies than RM widely used to accomplish SA, e.g. source oriented models. These other methodologies cover aspects of SA which are required in the AQD and are not addressed by RM. Performance assessment of such methodologies is out of the scope of this CEN/TS.

This document specifies a method for the sampling and analysis of NH3 in ambient air using diffusive sampling.
It can be used for NH3 measurements at ambient levels, but the concentration range and exposure time are sampler dependent, and the end user is therefore advised to match the sampler type to the measurement requirement and to follow the operating instructions provided by the manufacturer.

ISO 14966 specifies a method using scanning electron microscopy for determination of the concentration of inorganic fibrous particles in the air. The method specifies the use of gold-coated, capillary-pore, track-etched membrane filters, through which a known volume of air has been drawn. Using energy-dispersive X-ray analysis, the method can discriminate between fibres with compositions consistent with those of the asbestos varieties (e.g. serpentine and amphibole), gypsum, and other inorganic fibres. Annex C provides a summary of fibre types which can be measured. This document is applicable to the measurement of the concentrations of inorganic fibrous particles in ambient air. The method is also applicable for determining the numerical concentrations of inorganic fibrous particles in the interior atmospheres of buildings, for example to determine the concentration of airborne inorganic fibrous particles remaining after the removal of asbestos-containing products. The range of concentrations for fibres with lengths greater than 5 μm, in the range of widths which can be detected under standard measurement conditions (see 7.2), is approximately 3 fibres to 200 fibres per square millimetre of filter area. The air concentrations, in fibres per cubic metre, represented by these values are a function of the volume of air sampled. The ability of the method to detect and classify fibres with widths lower than 0,2 μm is limited. If airborne fibres in the atmosphere being sampled are predominantly <0,2 μm in width, a transmission electron microscopy method such as ISO 10312[8] can be used to determine the smaller fibres.

This document specifies a reference method using transmission electron microscopy for the determination of airborne asbestos fibres and structures in in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation for asbestos structures in any atmosphere. The specimen preparation procedure incorporates ashing and dispersion of the collected particulate, so that all asbestos is measured, including the asbestos originally incorporated in particle aggregates or particles of composite materials. The lengths, widths and aspect ratios of the asbestos fibres and bundles are measured, and these, together with the density of the type of asbestos, also allow the total mass concentration of airborne asbestos to be calculated. The method allows determination of the type(s) of asbestos fibres present. The method cannot discriminate between individual fibres of the asbestos and elongate fragments (cleavage fragments and acicular particles) from non-asbestos analogues of the same amphibole mineral[12].

This document, along with ISO 16000-38, specifies the measurement method for determining the mass concentration of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) or high-resolution mass spectrometry (HRMS). The analytical procedure is covered by this document. The sampling procedure and the manufacturing of the samplers are covered by ISO 16000-38. This document describes specifications for the chromatography and the mass spectroscopy for the amines. Measurement results are expressed in μg/m3. Although primarily intended for the measurement of amines listed in Tables A.1 and A.2, it can also be used for the measurement of other amines in indoor air. This document gives instructions and describes procedures for the inclusion of other amines. The range of application of this document concerning the concentrations of amines in indoor air depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range of application can be expected to be from approximately 0,002 μg/m3 (100 l sample) up to 2 000 μg/ m3 (5 l sample) for a common analytical equipment (e.g. Waters „TQD“) for the majority of the amines listed in Tables A.1 and A.2. The analysis of derivatives of ethanolamine is usually about 10 times more sensitive and the analysis of short-chained aliphatic amines is usually about 10 times less sensitive than
the analysis of an average amine. The performance data of the analytical method is given in Annex B, particularly in Tables B.1 and B.2. This document can be used also for the determination of amines in water if the detection limit is sufficient. This document does not cover the determination of isocyanates in indoor air (nor in water samples) as corresponding amines (covered by ISO 17734-1 and ISO 17734-2).

This document specifies a method for the determination of primary, secondary and tertiary aliphatic
and aromatic amines in indoor air using accumulated sampling and high-performance liquidchromatography
(HPLC) coupled with tandem mass spectrometry (MS-MS) or high resolution mass
spectrometry (HRMS). It specifies the sampling procedure for determining the mass concentration of
amines as mean values by sampling the amines on phosphoric acid impregnated filters. The analytical
procedure of the measurement method is covered by ISO 16000-39.
Measurements, performed with samplers containing phosphoric acid-impregnated inert supporting
material and operating at specified flow rates for specified sampling periods are described in this
document. Requirements regarding sample volume are also defined.
The range of application of this document concerning the concentrations of amines in indoor air depends
on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l),
the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity
of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range of application
can be expected to be from approximately 0,002 μg/m3 (100 l sample) up to 2 000 μg/m3 (5 l sample)
for a common analytical equipment1) for the majority of the amines listed in Annex A. The analysis of
derivatives of ethanolamine is usually about 10 times more sensitive and the analysis of short-chained
aliphatic amines is usually about 10 times less sensitive than the analysis of an average amine.
Although primarily intended for the measurement of amines listed in Annex A, this document can also
be used for the measurement of other amines in indoor air.
This document describes procedures for the fabrication and gives requirements for the use of glass
tubes containing impregnated filters out of phosphoric acid-impregnated glass wool as samplers, but
does not exclude other samplers with proven equal or improved properties. This document also gives
procedures for the demonstration of equivalence of other sampler types or methods.
This document does not cover the determination of amines in other media like water or soil.
Furthermore, it does not cover the determination of isocyanates in indoor air as corresponding amines
(covered by ISO 17734-1 and ISO 17734-2). Quaternary amines are also not included in this document.

This document specifies a reference method using transmission electron microscopy for the determination of airborne asbestos fibres and structures in in a wide range of ambient air situations, including the interior atmospheres of buildings, and for a detailed evaluation for asbestos structures in any atmosphere. The specimen preparation procedure incorporates ashing and dispersion of the collected particulate, so that all asbestos is measured, including the asbestos originally incorporated in particle aggregates or particles of composite materials. The lengths, widths and aspect ratios of the asbestos fibres and bundles are measured, and these, together with the density of the type of asbestos, also allow the total mass concentration of airborne asbestos to be calculated. The method allows determination of the type(s) of asbestos fibres present. The method cannot discriminate between individual fibres of the asbestos and elongate fragments (cleavage fragments and acicular particles) from non-asbestos analogues of the same amphibole mineral[12].

This document specifies a reference method for the determination of emissions from coatings into indoor air. This method is applicable to volatile organic compounds, semi-volatile organic compounds and volatile aldehydes.
NOTE 1   This document is aimed at describing the overall procedure and makes use of existing standards mainly by normative reference complemented when necessary with additional or modified normative requirements.
This document is mainly aimed at determining emission data in indoor air for the purpose of meeting national legislation requirements, and for the voluntary labelling of products.
NOTE 2   Harmonized product standards for coatings falling under the CPR can refer to this standard for the intended conditions of use.
This document applies to coatings for indoor use as listed in Clause 5.
It is not applicable for:
- coatings that are applied off site or coatings that are applied on site, prior to the structure being permanently weatherproof  except for the product type category 7 as listed in Clause 5;
- tinting pastes that are not ready for use as coating;
- non film-forming products like e.g. waxes and impregnations.

This document specifies a general laboratory test method for evaluating the reduction in concentration
of VOCs by sorptive building materials. This method applies to boards, wallpapers, carpets, paint
products, and other building materials. The sorption of those target compound(s), i.e. VOCs, can be
brought about by adsorption, absorption and chemisorption. The performance of the material, with
respect to its ability to reduce the concentration of VOCs in indoor air, is evaluated by measuring
area-specific reduction rate and saturation mass per area. The former directly indicates material
performance with respect to VOC reduction at a point in time; the latter relates to the ability to maintain
that performance.
This document is based on the test chamber method specified in ISO 16000-9.
NOTE Sampling, transport and storage of materials to be tested, and preparation of test specimens, are
described in ISO 16000-11. Air sampling and analytical methods to determine VOCs are described in ISO 16000-6
and ISO 16017-1.
