22、ment describes the quality assurance procedures related to automated measuring systems (AMS) for the determination of dust in waste gas, in order to meet the uncertainty requirements on measured values given by regulations, e.g. EU Directives (1), national or other legislation.This document is deriv

23、ed from EN 14181, which specifies general procedures for establishing quality assurance levels (QAL) for automated measuring systems (AMS) installed on industrial plants for the determination of the waste gas components and other waste gas parameters. It amends EN 14181 and provides guidance specifi

24、c to dust measurements. It is only applicable in conjunction with EN 14181.The calibration and validation of dust AMS is based on parallel measurements with the manual gravimetric standard reference method (SRM) described in EN 13284-1.This document was primarily developed for the measurement of emi

25、ssions from waste incinerators. From a technical point of view, it can be applied to other processes, for which measurement at an emission limit is required with defined uncertainty.4BS EN 13284-2:2017EN 13284-2:2017 (E)1 ScopeThis European Standard specifies requirements for the calibration and val

26、idation (QAL2), the ongoing quality assurance during operation (QAL3) and the annual surveillance test (AST) of automated measuring systems (AMS) used for monitoring dust emissions from stationary sources to demonstrate compliance with emission limit values (ELV) below 50 mg/m3at standard conditions

27、. It specifically deals with measurements in wet gases and at low concentrations.This document is derived from EN 14181 and is only applicable in conjunction with EN 14181.This document is applicable by direct correlation with the standard reference method (SRM) described in EN 13284-1.2 Normative r

The amen

38、dments specific to these AMS are specified in the following.6 Calibration and validation of the AMS (QAL2)6.1 GeneralThe AMS shall be calibrated and validated in accordance with EN 14181 with the modifications specified in 6.2 to 6.8.NOTE 1 Annex A shows an example of the application of QAL2 for an

39、automated dust measuring system.Extractive dust measuring systems shall be configured before calibration.NOTE 2 Annex B provides information on the configuration of extractive dust measuring systems.6.2 Functional testFunctional tests are performed to ensure that the AMS is working according to the

40、specifications and to check the active measurement components of the AMS to ensure they are not unduly influenced by dust contamination.The linearity test including the zero and span checks shall be carried out with surrogate reference materials, which have been approved as part of the performance t

41、est according to EN 15267-3.If the zero point is used to establish the calibration function according to EN 14181:2014, 6.4.3, Method b), a zero dust-offset test shall be performed to prove that the AMS gives a reading at or below detection limit (as demonstrated in QAL1) at a zero concentration. Th

42、e test results shall be presented in the calibration report.6.3 Parallel measurements with the SRM6.3.1 GeneralAccording to EN 14181 at least 15 parallel measurements shall be performed with the AMS and SRM in order to calibrate and validate the AMS by use of an independent method. The measurements

43、shall be performed at normal operation of the plant.The SRM used shall be applied in accordance with EN 13284-1.The number of parallel measurements may be reduced to a minimum of 5 valid measurements over 3 days, if all SRM measured results are expected to be below the maximum permissible uncertaint

44、y for the AMS measured values and approval is given by the competent authority. The total SRM sampling 7BS EN 13284-2:2017EN 13284-2:2017 (E)time shall be at least 7,5 h, which is equal to 15 times 30 min (see Annex C). The sampling duration shall be the same for all parallel measurements.NOTE Reduc

45、ing the number of measurements and increasing the individual SRM sampling time leads to a better quantification of very low dust concentrations.6.3.2 Increasing the dust concentrationThe dust concentrations are often close to zero compared to the ELV, if the dust cleaning equipment of the plant is o

46、perating normally. The calibration range can be extended in some cases by increasing the dust concentration. This can be achieved by e.g. changing the plant load, lowering the efficiency of the gas cleaning equipment, or by injecting dust of the same physical properties and ensuring homogeneous conc

47、entration across the measurement planes of the AMS and the SRM (see Annex D). The approach shall be agreed by both the plant operator and the competent authority and be fully documented in the calibration report.Increasing the dust concentration can lead to changes in the dust characteristics and ca

48、n influence the calibration function of AMS, which are cross-sensitive to particle size (e.g. optical devices). In these cases, a linear and a quadratic calibration function shall be calculated, and the most adequate calibration function shall be used (see 6.4.3).NOTE Calculation of a quadratic cali

49、bration function is described in Annex E.If the calibration range can be extended, then at least 15 parallel measurements shall be conducted in the extended calibration range in the following way: at least 5 measurements are performed in the normal operation range of the plant (i.e. at very low concentration); at least 5 measurements are performed at the upper limit of the extended calibration range; at least 5 measurements are performed at a dust concentration intermediate to these levels.6.3.3 SRM measured values below the limit of quantificati
