EN 14181:2004

This European Standard specifies procedures for establishing quality assurance levels (QALs) for automated measuring systems (AMS) installed on industrial plants for the determination of the flue gas components and other flue gas parameters. This European Standard specifies procedures for establishing quality assurance levels (QALs) for automated measuring systems (AMS) installed on industrial plants for the determination of the flue gas components and other flue gas parameters. This standard specifies:- a procedure (QAL 2) to calibrate the AMS and determine the variability of the measured values obtained by an automated measurement system which is suitable for the validation of an AMS following its installation; - a procedure (QAL 3) 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 QAL 1;- 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 standard is designed to be used after the AMS has been accepted according to the procedures specified in EN ISO 14956 (QAL 1). This standard is restricted to quality assurance (QA) of the AMS, and does not include QA of the data collection and recording system of the plant.
