This document specifies a chromatographic method for the determination of levoglucosan in aqueous or organic extracts of filter samples collected in accordance with EN 12341:2023 [5]. The method has been tested for concentrations of ca. 10 ng/m3 up to ca. 3 000 ng/m3 with a sampling duration of 24 h. The procedure is also suitable for the determination of galactosan and mannosan.
Depending on the analysis instrumentation used, the carbohydrates inositol, glycerol, threitol/erythritol, xylitol, arabitol, sorbitol, mannitol, threalose, mannose, glucose, galactose and fructose can also be determined. However, no performance characteristics are given for these compounds in this document.

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 part of EN 14662 gives general guidance for the sampling and analysis of benzene in air by pumped sampling, thermal desorption and capillary gas chromatography.
This part of EN 14662 is in accordance with the generic methodology selected as the basis of the European Union reference method for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values with a one-year reference period.
This part of EN 14662 is valid for the measurement of benzene in a concentration range of approximately 0,5 μg/m3 to 50 μg/m3 in an air sample typically collected over a period of 24 hours.
The upper limit of the useful range is set by the sorptive capacity of the sorbent and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capacity of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artefacts on the sorbent. Artefacts are typically sub ng for sorbents, but higher levels of aromatic hydrocarbons have been noted in other sorbents. The detection limit will be approximately 1/10 of the lower concentration range.
Expansion of Scope:
This part of EN 14662 provides general guidance for the sampling of benzene using either a single sampler, which is changed manually after every exposure period, or a multi-tube sampler capable of storing and exposing multiple samples sequentially without user intervention.

This document is in accordance with the generic methodology selected as the basis of the European Union reference method for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values with a one-year reference period.
This document is valid for the measurement of benzene in a concentration range of approximately 0,5 μg/m3 to 50 μg/m3. Air samples are typically collected over periods ranging from a few hours to 7 days.
The upper limit of the useful range is set by the sorptive capacity (the safe sampling volume) of the sorbent and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capacity of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artefacts on the sorbent. Artefacts are typically sub ng for graphitised carbon sorbents, but higher levels of aromatic hydrocarbons have been noted in other sorbents - e.g. porous polymers. The detection limit will be approximately 1/10 of the lower concentration range.

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 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 - 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 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 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.
