What is BS EN 14181– Quality assurance of automated measuring systems about?  
BS EN 14181 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.
BS EN 14181 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
BS EN 14181 is designed to be used after the AMS has been certified in accordance with the series of European Standards EN 15267.
Who is BS EN 14181– Quality assurance of automated measuring systems for? 
BS EN 14181 on stationary waste emissions is relevant to: 
- Product Engineers 
- Chemical Engineers 
- Quality assurance department 
- Manufacturers and industries using furnaces and gas towers 
- Researchers and scientists 
Why should you use BS EN 14181– Quality assurance of automated measuring systems? 
BS EN 14181 describes the quality assurance procedures related to automated measuring systems (AMS) for the determination of dust in the waste gas, to meet the uncertainty requirements on measured values given by regulations. 
BS EN 14181 was primarily developed for the measurement of emissions 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. 
Overall, BS EN 14181 provides manufacturers with technical information and test methods for measuring low range mass concentrations using a variety of methods and provides quality assurance for automated devices that will save time and improve productivity.
