ISO 11665-11:2016 describes radon-222 test methods for soil gas using passive and active in-situ sampling at depth comprised between surface and 2 m.
ISO 11665-11:2016 gives general requirements for the sampling techniques, either passive or active and grab or continuous, for in-situ radon-222 activity concentrations measurement in soil gas.
The radon-222 activity concentration in the soil can be measured by spot or continuous measurement methods (see ISO 11665‑1). In case of spot measurement methods (ISO 11665‑6), the soil gas sampling is active only. On the other hand, the continuous methods (ISO 11665‑5) are typically associated with passive soil gas sampling.
The measurement methods are applicable to all types of soil and are determined according to the end use of the measurement results (phenomenological observation, definition or verification of mitigation techniques, etc.) taking into account the expected level of the radon-222 activity concentration.
These measurement methods are applicable to soil gas samples with radon activity concentrations greater than 100 Bq/m3.
NOTE This part of ISO 11665 is complementary with ISO 11665‑7 for characterization of the radon soil potential.

ISO 11665-7:2012 gives guidelines for estimating the radon-222 surface exhalation rate over a short period (a few hours), at a given place, at the interface of the medium (soil, rock, laid building material, walls, etc.) and the atmosphere. This estimation is based on measuring the radon activity concentration emanating from the surface under investigation and accumulated in a container of a known volume for a known duration.
This method is estimative only, as it is difficult to quantify the influence of many parameters in environmental conditions. ISO 11665-7:2012 is particularly applicable, however, in case of an investigation, a search for sources or a comparative study of exhalation rates at the same site.

EN ISO 10121-1 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas-phase air cleaning media (GPACM) or GPACM configurations for use in gas-phase air cleaning devices intended for general filtration applications. This part of ISO 10121 is specifically intended for challenge testing and not for general material evaluation or pore system characterization. The three different types of GPACM identified in this part of ISO 10121 are GPACM-LF (particles of different shape and size intended for e.g. Loose Fill applications), GPACM-FL (FLat sheet fabric intended for e.g. flat one layer, pleated or bag type devices) and GPACM-TS (three dimensional structures that are many times thicker than flat sheet and e.g. used as finished elements in a device). The tests are conducted in an air stream and the GPACM configurations are challenged with test gases under steady-state conditions. Since elevated gas challenge concentrations (relative to general ventilation applications) are used, test data should be used to compare GPACM within the same configuration and not for the purpose of predicting performance in a real situation. It is also not implied that different GPACM configurations can be directly compared. The primary intention is to be able to compare like GPACM configurations to like, not between GPACM configurations. Testing of complete devices is described in ISO 10121-2. To ensure objectivity for test equipment suppliers, no specific design of the test apparatus is defined: an example is illustrated in Annex C (informative). Instead normative demands for media sample holder design, apparatus properties and validation tests are specified.

This part of ISO 28902 mainly specifies the requirements in order to perform visual range lidar measurements for the determination of direction-dependent meteorological optical range (MOR). The term "visual-range lidar" is used in this part of ISO 28902 to apply to the lidar systems making visual-range measurements, commonly referred to as "visibility measurements". Due to physical approximations, quantitative determination is limited to a meteorological optical range of between 30 m and 2 000 m. For this range, this part of ISO 28902 specifies the performance of visual-range lidar systems utilizing the method of range‑integrated visual-range measurements based on light extinction. The following parameters can be calculated based on the directiondependent meteorological optical range: a) horizontal visual range; b) vertical visual range; c) slant visual range. NOTE The measures for visibility are strongly related to the historical definitions of visibility, which are related to human observers. The lidar technique extends the definitions to various conditions, such as daylight and night-time conditions. In addition, this measurement principle enables the user to retrieve information on cloud base height, boundary layer depth, fog banks and aerosol profiles due to the signal attenuation by water vapour and/or aerosols. Examples of these applications are given in Annex C. This part of ISO 28902 can be applied in the following areas: — meteorological stations; — airports; — harbours; — waterways; — roads and motorways; — automotive; — oil platforms.

This document specifies a method for the objective determination of the odour concentration of a gaseous sample using dynamic olfactometry with human assessors. The standard also specifies a method for the determination of the emission rate of odours from stationary sources, in particular:
-   point sources (conveyed or ducted emissions);
-   active area sources (e.g. biofilters);
-   passive sources.
The primary application of this standard is to provide a common basis for evaluation of odour emissions.
When this document is used for the determination of the odour concentration or the odour emission rate of stationary source emissions, the other relevant European Standards concerning stationary source emissions apply, in particular EN 15259 and EN 16911-1, especially when measurements have to be in compliance with the relevant European Directives concerning industrial air emissions.
Even so, the analysis/quantification step of the measurement method described in this document (i.e. the determination of the odour concentration of an odorous gas sample, without respect to the origin of the sample itself) can be fully applied in many cases not related with industrial emission sources (e.g. the measurement of the mass concentration at the detection threshold of pure odorous substances, the determination of effectiveness of deodorizing systems for indoor air). In those latter cases, the requirements in this document concerning the measurement planning and the sampling of stationary sources  can be ignored or adapted.
This document is applicable to the measurement of odour concentration of pure substances, defined odorant compounds and undefined mixtures of odorant volatiles in air or nitrogen, using dynamic olfactometry with a panel of human assessors being the sensor. The unit of measurement is the European odour unit per cubic metre: ouE/m3. The odour concentration is measured by determining the dilution factor required to reach the detection threshold. The odour concentration at the detection threshold is by definition 1 ouE/m3. The odour concentration is then expressed in terms of multiples of the detection threshold. The range of measurement is typically from 101 ouE/m3 to 107 ouE/m3 (including pre dilution).
The field of application of this document includes:
-   the measurement of the mass concentration at the detection threshold of pure odorous substances in g/m3;
-   the determination of the EROM value of odorants, in mol;
-   the measurement of the odour concentration of mixtures of odorants in ouE/m3;
-   the measurement of the emission rate of odorous emissions from point sources, active area sources and passive area sources, including pre dilution during sampling;
-   the sampling of odorous gases from emissions of high humidity and temperature (up to 200 °C);
-   the determination of effectiveness of end-of-pipe mitigation techniques used to reduce odour emissions.
The determination of odour emissions requires measurement of gas velocityto determine the gas volume flow rate.
The field of application of this document does not include:
-   the measurement of odours potentially released by particles of odorous solids or droplets of odorous fluids suspended in emissions;
-   the measuring strategy to be applied in case of variable emission rates;
-   the measurement of the relationship between odour stimulus and assessor response above detection threshold (perceived intensity);
-   measurement of hedonic tone (or (un)pleasantness) or assessment of annoyance potential;
-   direct measurement of odour exposure in ambient air. For this measurement purpose, field panel methods exist which are the subject of CEN standard EN 16841-1, Ambient Air - Determination of odour in ambient air by using field inspection - Grid method;
-   direct olfactometry, including field olfactometry;
-   static olfactometry;
-   measurement of odour recognition thresholds;
-   measurement of odour identification thresholds.
