CEN/TR 15983:2010 (E) 4 Introduction This CEN Technical Report provides supporting guidance on the application of EN 14181:2004. It is based on the growing experiences with EN 14181:2004 throughout the CEN member c
12、ountries. EN 14181:2004 specifies three levels of quality assurance (QAL), known as QAL1, QAL2 and QAL3 as well as an Annual Surveillance Test (AST). This Technical Report explains the requirements of these levels of quality assurance to achieve a consistent application of EN 14181:2004. CEN/TR 1598
13、3:2010 (E) 5 1 Scope This CEN Technical Report provides guidance for applying the European Standard EN 14181:2004. This CEN Technical Report provides guidance only on applying the quality assurance levels QAL1, QAL2 and QAL3 as well as the Annual Surveillance Test (AST). This CEN Technical Report is
14、 an informative document. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 air quality characteristic one of the quantifiable properties relating to an air mass under investigation, for example, concentration of a constituent EN 14181:2004, 3.
15、1 2.2 automated measuring system AMS measuring system permanently installed on site for continuous monitoring of emissions EN 14181:2004, 3.2 NOTE 1 An AMS is the automated application of a monitoring method, which is traceable to a reference method. NOTE 2 Apart from the analyser, an AMS includes f
16、acilities for taking samples (e.g. sample probe, sample gas lines, flow meters, regulators, delivery pumps) and for sample conditioning (e.g. dust filter, moisture removal devices, converters, diluters). This definition also includes testing and adjusting devices that are required for regular functi
17、onal checks. 2.3 calibration function linear relationship between the values of the SRM and the AMS with the assumption of a constant residual standard deviation EN 14181:2004, 3.3 NOTE The calibration function is established during QAL2 on stack gases. 2.4 competent authority organisation which imp
18、lements the requirements of EU Directives and regulates installations, which must comply with the requirements of applicable European Standards EN 15267-1:2009, 3.3 2.5 confidence interval (two-sided) when T1 and T2 are two functions of the observed values such that, being a population parameter to
19、be estimated, the probability Pr(T1 T2) is at least equal to (1 ) where (1 ) is a fixed number, positive and less than 1, the interval between T1 and T2 is a two-sided (1 ) confidence interval for CEN/TR 15983:2010 (E) 6 EN 14181:2004, 3.5 2.6 CUSUM chart calculation procedure in which the amount of
20、 drift and change in precision is compared to the corresponding uncertainty components which are obtained during QAL1 EN 14181:2004, 3.6 2.7 drift monotonic change of the calibration function over stated period of unattended operation, which results in a change of the measured value EN 14181:2004, 3
21、.7 NOTE This refers to a change in the response of the AMS to a determinant which does not change. 2.8 emission limit value ELV limit value related to the uncertainty requirement EN 14181:2004, 3.8 NOTE For EU Directives it is the daily emission limit value that relates to the uncertainty requiremen
22、t. 2.9 extractive AMS AMS having the detection unit physically separated from the gas stream by means of a sampling system EN 14181:2004, 3.9 2.10 instability change in the measured value comprised of drift and dispersion resulting from the change in the calibration function over a stated period of
23、unattended operation, for a given value of the air quality characteristic NOTE 1 Drift and dispersion specify the monotonic and stochastic change with time of the output signal, respectively. NOTE 2 This refers to a change in the response of the AMS to a determinant which does not change. NOTE 3 Ada
24、pted from EN 14181:2004, 3.10. 2.11 instrument reading indication of the measured value directly provided by the AMS without using the calibration function EN 14181:2004, 3.11 2.12 intrinsic uncertainty uncertainty component originating from the AMS itself, independent of the installation 2.13 legis
