15、N 14181:2004. It is based on the growing experiences with EN 14181:2004 throughout the CEN member countries. 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

16、these levels of quality assurance to achieve a consistent application of EN 14181:2004. PD CEN/TR 15983:2010CEN/TR 15983:2010 (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 q

17、uality assurance levels QAL1, QAL2 and QAL3 as well as the Annual Surveillance Test (AST). This CEN Technical Report is 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 quantifiabl

19、ion of a monitoring method, which is traceable to a reference method. NOTE 2 Apart from the analyser, an AMS includes facilities 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,

20、converters, diluters). This definition also includes testing and adjusting devices that are required for regular functional 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

21、NOTE The calibration function is established during QAL2 on stack gases. 2.4 competent authority organisation which implements 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 i
