Full title and description

PD CEN/TR 17911:2023 — Stationary source emissions. Guideline for the elaboration of standardized measurement methods. Recommendations for the structure and content. This technical report provides recommended structure, common elements and drafting text (including an electronic template) to harmonize CEN/TC 264 documents that specify measurement methods for emissions from stationary sources.

Abstract

CEN/TR 17911:2023 is a guidance document intended to support working groups and authors when preparing standardized measurement methods (reference, alternate or automated methods) for stationary source emissions. It describes the essential sections a method should contain (scope, principle, measuring system, sampling and sample handling, performance characteristics, QA/QC, reporting and annexes) and is supplemented by an electronic template (Annex A) to ensure consistent presentation and content across EN, CEN/TS and CEN/TR documents.

General information

• Status: CEN Technical Report (CEN/TR), published and in force / adopted as national PD documents in several member bodies.
• Publication date: Published February–March 2023 (national PD adoptions and transpositions appeared March–June 2023).
• Publisher: European Committee for Standardization (CEN); issued as CEN/TR 17911:2023 and made available by national standards bodies as PD / identical national publications (examples: BSI PD, DIN, AENOR, SIS).
• ICS / categories: 13.040.40 — Stationary source emissions / air quality (emissions measurement).
• Edition / version: Edition 1 (CEN/TR 17911:2023).
• Number of pages: Typically published as 21–24 pages in national releases (common national PDFs show 21–24 pages; some distributors list up to ~28 pages depending on front matter).

Scope

This report supports the elaboration of standardized measurement methods for the determination of stationary source emissions by manual or automated measurement techniques. It defines the basic elements and minimum content a method should include, and supplies an electronic template for consistent drafting. The guidance is primarily addressed to working groups of CEN/TC 264 (Air quality) preparing EN, CEN/TS or CEN/TR documents on emissions measurement.

Key topics and requirements

• Clear definition of scope and measurand: field of application, measurand(s), measurement and validation ranges, and explicit exclusions.
• Principle and measuring system: description of measurement principles and full specification of equipment, sampling probes, conditioning, converters, materials and reagents where applicable.
• Sampling and sample handling: recommended practices for representative sampling, sample conditioning and preservation when applicable.
• Performance characteristics and validation: requirements for accuracy, precision, detection/quantification limits, calibration/validation ranges and uncertainty assessment.
• Quality assurance and quality control (QA/QC): required checks, calibration procedures, reference/parallel measurements and documentation to demonstrate fitness for purpose (consistent with CEN QA frameworks for AMS/CEMS where relevant).
• Reporting and documentation: standardised content for test reports, certificates, and annex material (including informative example texts in the electronic template).
• Electronic template (Annex A): a ready-to-use structure and suggested text blocks to harmonise presentation across documents.

Typical use and users

Primary users are CEN/TC 264 working groups and national technical committees drafting emission measurement standards, method authors, test laboratories, conformity assessment bodies, environmental regulators and industrial testing teams that develop or apply standardized sampling and measurement methods for stationary source emissions. The document is used as a drafting and harmonisation aid rather than a prescriptive measurement standard.

Related standards

Key related CEN/EN standards and series commonly used alongside CEN/TR 17911 include EN 14181 (quality assurance of automated measuring systems / CEMS), EN 13284-1 and EN 13284-2 (reference and QA for dust/particulate measurements), and the EN 15267 series (certification/performance criteria for automated measuring systems). These documents cover validation, performance testing, QA levels (QAL1–QAL3) and SRM/AMS relationships that measurement methods will normally reference or align with.

FAQ

Q: What is this standard?

A: CEN/TR 17911:2023 is a CEN Technical Report providing guidance and a template for drafting standardized measurement methods for stationary source emissions; it is intended to harmonise structure and content of method documents produced under CEN/TC 264.

Q: What does it cover?

A: It covers the recommended sections and minimum content for emission measurement methods (scope, principle, measuring system, sampling, performance, QA/QC, reporting) and includes an electronic template (Annex A) with suggested text blocks to promote consistency. It is guidance, not a prescriptive reference method itself.

Q: Who typically uses it?

A: Working groups drafting CEN emission measurement standards, national standards bodies issuing PD/adopted versions, test laboratories, conformity assessment bodies and regulators who need consistent method structure and reporting across standards and methods.

Q: Is it current or superseded?

A: CEN/TR 17911:2023 was published and made available in national catalogues in early 2023 and is the current CEN technical report on this subject (no superseding CEN/TR was published at the time of publication). Users should check national catalogues for the latest status and any subsequent revisions or amendments.

Q: Is it part of a series?

A: It is part of the body of documents developed under CEN/TC 264 (Air quality) and intended to work together with method-specific EN standards and quality-assurance/performance standards (for example EN 14181, EN 13284 series and EN 15267 series). It is a guidance TR rather than a numbered “part” of a single EN series.

Q: What are the key keywords?

A: Stationary source emissions; method template; sampling and sample handling; measurement uncertainty; QA/QC; automated measuring systems (AMS); CEMS; CEN/TC 264.
