Air quality - Certification of automated measuring systems - Part 4: Performance criteria and test procedures for automated measuring systems for periodic measurements of emissions from stationary sources

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

EN 15267-4:2017 (E) 5 European foreword This document (EN 15267-4:2017) has been prepared by Technical Committee CEN/TC 264 “Air quality”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document is Part 4 of a series of European Standards: — EN 15267-1, Air quality — Certification of automated measuring systems — Part 1: General principles — EN 15267-2, Air quality — Certification of automated measuring systems — Part 2: Initial assessment of the AMS manufacturer’s quality management system and post certification surveillance for the manufacturing process — EN 15267-3, Air quality — Certification of automated measuring systems — Part 3: Performance criteria and test procedures for automated measuring systems for monitoring emissions from stationary sources — EN 15267-4, Air quality — Certification of automated measuring systems — Part 4: Performance criteria and test procedures for automated measuring systems for periodic measurements of emissions from stationary sources According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 15267-4:2017

EN 15267-4:2017 (E) 6 0 Introduction 0.1 General CEN has established standards for the certification of automated measuring systems (AMS) used for monitoring emissions from stationary sources and ambient air quality. This product certification is based on the following four sequential stages: a) performance testing of the AMS; b) initial assessment of the AMS manufacturer’s quality management system; c) certification of the AMS; d) post certification surveillance. This European Standard 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 standard reference methods for different measured components are listed in Annex F. 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 European Standard supports the requirements of the following EU Directives: — Directive 2010/75/EU on industrial emissions (integrated pollution prevention and control) — Directive 2003/87/EC on processes emitting greenhouse gases. However, this European Standard 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.

SIST EN 15267-4:2017

EN 15267-4:2017 (E) 7 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 European Standard.

0.6 Performance characteristics A combination of laboratory and field tests is detailed within this European Standard. Laboratory testing is designed to assess whether a P-AMS can meet, under controlled conditions, the relevant performance criteria. Field testing, is designed to assess whether a 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 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 stack gas other than the measured component; — converter efficiency for NOx P-AMS; — response factors for P-AMS measuring TOC; — reproducibility under field conditions; — 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. SIST EN 15267-4:2017

EN 15267-4:2017 (E) 8 This European Standard is an application and elaboration of EN ISO 9169 with additional and alternative provisions for the performance test of P-AMS. Where this European Standard 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 EN 15267-3 This European Standard is based on EN 15267-3, which specifies the performance testing of stationary AMS for the continuous monitoring of emissions from stationary sources. Many requirements of this European Standard are identical to those of EN 15267-3. This European Standard deviates from EN 15267-3 only where the portable use and the use as SRM or AM require different or additional requirements. Therefore, this European Standard allows a combined testing where an AMS is designed for stationary and portable use. It also allows a reduced performance testing of P-AMS, which have been already certified according to EN 15267-3 for stationary use.

SIST EN 15267-4:2017

EN 15267-4:2017 (E) 9 1 Scope This European Standard specifies the general performance criteria and test procedures for portable automated measuring systems (P-AMS) used for periodic measurements of stationary source emissions. It applies to the performance testing of P-AMS based on measurement techniques specified by the standard reference method (SRM) or an alternative method (AM).

Performance testing is based on the general performance criteria and test procedures specified in this European Standard 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 European Standard supports the requirements of particular EU Directives. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
