Stationary source emissions - Quality assurance of automated measuring systems
This document specifies procedures for establishing quality assurance levels (QAL) for automated measuring systems (AMS) installed on industrial plants for the determination of the flue gas components and other flue gas parameters.
This document specifies:
— a procedure (QAL2) to calibrate the AMS and determine the variability of the measured values obtained by it, so as to demonstrate the suitability of the AMS for its application, following its installation;
— a procedure (QAL3) to maintain and demonstrate the required quality of the measurement results during the normal operation of an AMS, by checking that the zero and span characteristics are consistent with those determined during QAL1;
— a procedure for the annual surveillance tests (AST) of the AMS in order to evaluate (i) that it functions correctly and its performance remains valid and (ii) that its calibration function and variability remain as previously determined.
This document is designed to be used after the AMS has been certified in accordance with the series of documents EN 15267.

Emisije nepremičnih virov - Zagotavljanje kakovosti avtomatskih merilnih sistemov
Ta dokument je kot standard EN 14181:2014 pripravil Evropski odbor za standardizacijo (CEN), sprejet pa je bil brez sprememb.
Ta dokument določa postopke za vzpostavitev ravni zagotavljanja kakovosti (QAL) za avtomatske merilne sisteme, nameščene v industrijskih obratih za ugotavljanje komponent dimnega plina in drugih parametrov dimnega plina.
Ta dokument določa:
– postopek (QAL2) za kalibriranje avtomatskega merilnega sistema in ugotavljanje variabilnosti z njim pridobljenih izmerjenih vrednosti, da se dokaže primernost avtomatskega merilnega sistema za uporabo po njegovi namestitvi;
– postopek (QAL3) za vzdrževanje in dokazovanje potrebne kakovosti rezultatov meritev med običajnim delovanjem avtomatskega merilnega sistema s preverjanjem, da so značilnosti ničelne točke in merilnega območja skladne z značilnostmi, ki so ugotovljene med postopkom QAL1;
– postopek za letne nadzorne teste (AST) avtomatskega merilnega sistema, s katerimi se oceni, (i) ali pravilno deluje in daje veljavne rezultate ter (ii) ali sta njegova funkcija kalibracije in variabilnost še vedno v stanju, kot je bilo predhodno ugotovljeno.
Ta dokument se uporablja po certifikaciji avtomatskega merilnega sistema v skladu s serijo dokumentov EN 15267.
