Frequently Asked Questions
CEN/TC 264/WG 18 is a Working Group within the European Committee for Standardization (CEN). It is named "Open path optical methods for the measurement of ambient air quality". This committee has published 2 standards.
CEN/TC 264/WG 18 develops CEN standards. Currently, there are 2 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This European Standard describes the operation of active DOAS measuring systems with continuous radiation source, the calibration procedures and applications in determining gaseous constituents (e.g. NO2, SO2, O3, BTX, Hg) in ambient air or in diffuse emissions.

This European Standard is applicable to open-path absorption measurements of 'concentration path length' product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicable to the continuous measurement of infrared active organic and inorganic compounds in the gaseous state in ambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatial average.
