This European Standard specifies the conversion of raw data from an automated measuring system (AMS) to reported data by a data acquisition and handling system (DAHS). This specification includes:
- requirements for the handling of data,
- requirements for the reporting of data,
- calculation procedures required.
The main items covered by this European Standard are given by, but not limited to raw data acquisition, raw data validation, data correction and data averaging.

ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

This European Standard 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 European Standard 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 European Standard is designed to be used after the AMS has been certified in accordance with the series of European Standards EN 15267.

This European Standard specifies the following requirements:
a)   requirements for measurement sections and sites with respect to performing emission measurements;
b)   requirements for the measurement objective, plan and report of emission measurements of air pollutants and reference quantities to be carried out in waste gas ducts at industrial plants.
This European Standard applies to periodic measurements using manual or automated reference methods (RM).
This European Standard specifies generic principles which can be applied to perform emission measurements at different plant types and to meet different measurement objectives.
NOTE   The measurement objective is specified by the customer. The testing institute identifies the measurement objective and related regulatory requirements at the beginning of the measurement planning. Where measurements are being made for regulatory purposes, the customer should seek approval from the competent authority.
This European Standard specifies procedures for taking representative samples in waste gas ducts.
This European Standard specifies a procedure for finding the best available sampling point for automated measuring systems used for continuous monitoring of emissions.
The planning and reporting aspects of this European Standard are applicable to emission measurements at diffusive and fugitive emission sources.
This European Standard does not address aspects of structural safety of chimneys and ducts, construction of working platforms and safety of personnel using them.
