European foreword
This document (prEN 15267-4:2022) has been prepared by Technical Committee CEN/TC 264 “Air
quality”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15267-4:2017.
In comparison with the previous edition, the following technical modifications have been made:
a) The title of the revised EN 15267 series has been clarified to avoid the impression that all parts deal
with the certification of automated measuring systems. The title has been generalized so that
specifically Part 1 and Part 2 are also applicable to other air quality monitoring equipment.
b) The title of revised EN 15267-4 has been clarified to make it clear that Part 4 deals with portable
automated measuring systems for periodic measurements of emissions from stationary sources.
c) The performance criteria test and procedures were adapted to the state of the art in measurement
technology.
d) Requirements for portable automated measuring systems measuring mercury have been added.
e) References have been updated.
This document is Part 4 of a series of European Standards:
— EN 15267-1, Air quality — Assessment of air quality monitoring equipment — Part 1: General
principles of certification
— EN 15267-2, Air quality — Assessment of air quality monitoring equipment — Part 2: Initial assessment
of the manufacturer’s quality management system and post certification surveillance for the

Introduction
0.1  General
The assessment of air quality monitoring equipment (AQME) supports the requirements of certain
Directives of the European Union (EU), which require, either directly or indirectly, that this equipment
complies with performance criteria, maximum permissible measurement uncertainties and test
requirements. These Directives include the Directive 2010/75/EU on industrial emissions (IED),
Directive (EU) 2015/2193 on medium combustion plants and the Directive 2008/50/EC on ambient air
quality and cleaner air for Europe.
The assessment of AQME consists of the following sequential stages:
a) performance testing;
b) initial assessment of the manufacturer’s quality management system (QMS);
c) certification;
d) surveillance for the manufacturing process.
This document specifies the performance criteria and test procedures for performance testing of portable
automated measuring systems (P-AMS) used for periodic measurements of stationary source emissions.
Testing applies to complete measuring systems.
NOTE 1 Portable electrical apparatus designed to measure combustion flue gas parameters of heating appliances
are specified in EN 50379–1 to EN 50379–3.
The application of P-AMS for periodic measurements of stationary source emissions is based on
— specification of the standard reference method (SRM) and validation of the SRM;
— specification of the alternative method (AM) if the P-AMS is based on an AM;
— certification of the P-AMS in accordance with EN 15267-1, EN 15267-2 and EN 15267-4 including
demonstration of equivalence with the SRM in the field if the P-AMS is based on an AM;
— on-going quality management by the user of the P-AMS in line with EN ISO/IEC 17025.
NOTE 2 Examples for SRM and AM for different measured components are listed in Annex A.
The overall assessment for the purposes of certification is conformity testing, while the evaluation of
performance against specified performance criteria is performance testing.
0.2  Legal drivers
This document supports at least the requirements of the following EU Directives:
— Directive 2010/75/EU on industrial emissions;
— Directive (EU) 2015/2193 on the limitation of emissions of certain pollutants into the air from
medium combustion plants;
— Directive 2003/87/EC establishing a system for greenhouse gas emission allowance trading.
However, this document can also be applied to the monitoring requirements specified in other
EU Directives.

0.3  Periodic measurements
Certified P-AMS can be used as SRM or AM for periodic measurements of stationary source emissions.
0.4  Relationship to EN 14181
Certified P-AMS can be used as SRM or AM for the calibration and validation of stationary AMS for QAL2
and AST purposes.
0.5  Processes
Field testing of P-AMS is ordinarily carried out on industrial processes representative of the range of
application of the SRM or AM. The premise is that if the P-AMS performs acceptably on these processes,
then experience has shown that the P-AMS generally performs well on the majority of other processes.
However, there are always exceptions and it is the responsibility of the user to ensure that the P-AMS
performs adequately on a specific process.
The necessary field test of P-AMS is specified in this document.
0.6  Performance characteristics
A combination of laboratory test and field test is detailed within this document. The laboratory test is
designed to assess whether P-AMS can meet, under controlled conditions, the relevant performance
criteria. The field test is designed to assess whether P-AMS can continue to work and meet the relevant
performance criteria in real applications including transportation to the measurement site, set-up of the
P-AMS and measurement.
The main P-AMS performance characteristics are:
— response time;
— repeatability standard deviation;
— lack of fit (linearity);
— short-term drift;
— influence of ambient temperature;
— influence of supply voltage variations;
— influence of vibration;
— influence of sample gas pressure;
— influence of sample gas flow for extractive P-AMS;
— cross-sensitivity to likely interferents contained in the waste gas other than the measured
component;
— converter efficiency for P-AMS measuring NO ;
x
— converter efficiency of P-AMS measuring Hg;
— response factors for P-AMS measuring TOC;
— reproducibility;

---------------------- Page: 9 ----------------------
oSIST prEN 15267-4:2022
prEN 15267-4:2022 (E)
— trueness and precision of the P-AMS against the SRM under field conditions if the P-AMS is based on
an AM.
Additional performance characteristics specific to the SRM or AM are included in the performance test.
The quality assurance and quality control (QA/QC) procedures to be applied by the user of the P-AMS are
also assessed in the performance test.
This document is an application and elaboration of EN ISO 9169 with additional and alternative
provisions for the performance test of P-AMS. Where this document appears to differ from EN ISO 9169,
it either elaborates upon the requirements of EN ISO 9169 or differs in minor ways owing to the necessity
to conduct the performance test of P-AMS.
0.7  Relationship to prEN 15267-3
This document is based on prEN 15267-3, which specifies the performance test of stationary AMS for the
continuous monitoring of emissions from stationary sources. Many requirements of this document are
identical to those of prEN 15267-3. This document deviates from prEN 15267-3 only where the portable
use and the use as SRM or AM require different or additional requirements. Therefore, this document
allows a combined testing according to prEN 15267-3 and prEN 15267-4 where an AMS is designed for
stationary and portable use. It also allows a reduced performance test of P-AMS, which have been already
certified according to prEN 15267-3 for stationary use.

1 Scope
This document specifies the general performance criteria and test procedures for the performance test
of portable automated measuring systems (P-AMS) used for periodic measurements of stationary source
emissions. It applies to the performance test of P-AMS based on measurement techniques specified by
the standard reference method (SRM) or an alternative method (AM).
The performance test is based on the general performance criteria and test procedures specified in this
document and on the specific requirements specified for the SRM or AM. This includes testing of the
applicability and correct implementation of the QA/QC procedures specified for the SRM or AM.
This document supports the requirements of particular EU Directives.
