CEN/TC 264/WG 40 develops CEN standards in the area of Information technology. 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 document specifies a measurement method based on an automatic method for determination of the mass concentration of formaldehyde in ducts and stacks emitting to the atmosphere. It specifies the sampling and gas conditioning system. Furthermore, it specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) using appropriate techniques to measure formaldehyde.
This method is intended for intermittent monitoring of formaldehyde emissions as well as for the calibration and validation of automated formaldehyde measuring systems.
The analyser is calibrated using test gases produced by a test gas generator.

This document specifies the reference method for the determination of the concentration of formaldehyde in emissions from stationary sources. Waste gas samples are taken by absorption in water and subsequently analysed by spectrophotometry or HPLC. The method applies to waste gases in which the formaldehyde concentration is 2 mg/m3 to 60 mg/m3, on dry basis, at the reference conditions of 273 K and 101,3 kPa.
The specific components and the requirements for the measuring system are described. A number of performance characteristics with associated minimum performance criteria are specified for the measuring system.
