BS EN 15267-4:2017EN 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

34、 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 manufacturers quality management system; c) certification of the AMS; d) post certification surveillance. This European Standard spec

35、ifies 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

36、 flue gas parameters of heating appliances are specified in EN 503791 to EN 503793. 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 (A

37、M) 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.

38、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

39、 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 monitor

40、ing 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 f

41、or QAL2 and AST purposes. BS EN 15267-4:2017EN 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 experien

42、ce 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 St

43、andard. 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 wheth

44、er 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 (lineari

45、ty); 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

46、; converter efficiency for NOxP-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 inclu

47、ded 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. BS EN 15267-4:2017EN 15267-4:2017 (E) 8 This European Standard is an application and elaboration of EN ISO 9169 with additional

48、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 15

49、267-3 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 stati
