M/401 - Field air emission
Standardisation mandate to CEN for the creation of a European standard on volumetric flow from stationary sources in the field of air emissions
Mandate M/401 is a standardisation request from the European Commission to CEN, aimed at developing a European standard for measuring volumetric flow from stationary sources in the field of air emissions. The mandate focuses on establishing harmonised methods and criteria to accurately quantify air pollutant emissions for regulatory and monitoring purposes. This standard will ensure consistency and reliability in emission reporting, supporting environmental protection and compliance with EU air quality legislation. The decision on the approval of this mandate was addressed in the CEN/BT resolution C16/2007.
Purpose
The mandate M/401 aims to develop a European standard addressing the measurement of volumetric flow from stationary sources within the field of air emissions. The goal is to harmonize methods for determining the volume of air pollutants emitted by fixed installations, improving reliability and comparability across the EU.
Standardisation request
This mandate requests the European Committee for Standardization (CEN) to create a standard specifically focused on the measurement of volumetric flow related to stationary sources emitting air pollutants. The standard will set out the technical and procedural requirements to accurately quantify air emissions in terms of volumetric flow.
Expected deliverables
- A European Standard that defines the methodology for measuring volumetric flow from stationary air emission sources.
- Technical specifications ensuring consistent and reliable calculations of air pollutant volumes.
- Guidance on applying the standard in regulatory and monitoring frameworks within the EU.
Context
Given the importance of air quality and environmental protection in the EU, standardized measurement approaches for emissions are crucial. Volumetric flow measurement is a fundamental component in calculating pollutant output from stationary sources such as factories, power plants, or other fixed installations. This mandate supports the broader regulatory framework targeting air pollution reduction and compliance monitoring by providing recognized, standardized methods to quantify emissions at the European level.
The resolution reference CEN/BT C16/2007 indicates formal adoption or approval actions related to this mandate within CEN’s governing bodies.
The mandate covers the development of a European standard on measuring volumetric flow from stationary sources related to air emissions, focusing on standardisation in the field of air pollution control and environmental monitoring of industrial exhaust gases.

ISO 16911-2:2013 describes specific requirements for automated measuring system (AMS) flow monitoring. It is partly derived from EN 14181 which is the general document on the quality assurance of AMSs and is applicable in conjunction with that document.
ISO 16911-2:2013 specifies conditions and criteria for the choice, mounting, commissioning and calibration of AMSs used for determining the volume flow rate from a source in ducted gaseous streams. ISO 16911-2:2013 is applicable by correlation with the manual reference methods described in ISO 16911-1.
ISO 16911-2:2013 is primarily developed for monitoring emissions from waste incinerators and large combustion plants. From a technical point of view, it can be applied to other processes for which flow rate measurement is required with a defined and minimized uncertainty.

ISO 16911-1:2013 specifies a method for periodic determination of the axial velocity and volume flow rate of gas within emissions ducts and stacks. It is applicable for use in circular or rectangular ducts with measurement locations meeting the requirements of EN 15259. Minimum and maximum duct sizes are driven by practical considerations of the measurement devices described within ISO 16911-1:2013.
ISO 16911-1:2013 requires all flow measurements to have demonstrable metrological traceability to national or international primary standards.
To be used as a standard reference method, the user is required to demonstrate that the performance characteristics of the method are equal to or better than the performance criteria defined in ISO 16911-1:2013 and that the overall uncertainty of the method, expressed with a level of confidence of 95 %, is determined and reported. The results for each method defined in ISO 16911-1:2013 have different uncertainties within a range of 1 % to 10 % at flow velocities of 20 m/s.
Methods further to these can be used provided that the user can demonstrate equivalence, based on the principles of CEN/TS 14793.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/401 is a European Standardization Mandate titled "Standardisation mandate to CEN for the creation of a European standard on volumetric flow from stationary sources in the field of air emissions". Standardisation mandate to CEN for the creation of a European standard on volumetric flow from stationary sources in the field of air emissions There are 6 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
