This standard specifies procedures that shall be carried out to cover quality assurance of automated measuring systems (AMS) installed on industrial plants for the determination of the flue gas components and other flue gas parameters. This includes the calibration and the determination of the variability of the measured values for comparison with stated uncertainties by means of parallel measurements using a standard reference method. Furthermore, the standard includes a procedure for operational activities necessary to maintain the required quality of the measurement results, as well as a procedure for the annual surveillance tests on the AMS.
