    Emission Measurement (LasIR HCl/H2O)

    Designación del modelo:
    LasIR HCl/H2O

  • Estándares cumplidos
  • Fecha de emisión
    2022-03-02
  • Tipo de Certificado
    Suitability Tested

    European Type Approval

    The basis for the certification is the European standard

    • EN 15267  Air quality – Certification of automated measuring systems
      • part 1: General principles
      • part 2: Initial assessment of the AMS manufacturer´s quality management system
        and post certification surveillance for the manufacturing process

    Furthermore emission measurement systems apply to the requirements of
    EN 15267part 3: Performance criteria and test procedures for automated measuring
    systems for monitoring emissions from stationary sources

    Ambient air monitoring systems apply to the requirements of the standard series VDI 4202
    as well as the EN standards for gases respectively the EC guideline for particle.

    Emission data aquisition and handling systems (DAHS) apply to the requirements of
    "German uniform practice for emission monitoring,
    suitability test of measuring and evaluating-systems for continuous emission measurement",
    and the definitions for remote data transmission.

    The essential test items are:

    The lab test

    The measuring instrument is subjected to a detailed functional test, consisting of:

    • Check of the operating instruction on completeness, correctness and intelligibility
    • Check and verification of all device functions
    • Examination of quality of the lack-of-fit
    • Examination of response time and detection limits
    • Examination of repeatability standard deviation at zero and span point
    • Examination of cross sensitiveness
    • Examination of drift at zero and reference point
    • Examination of influence of ambient temperature
    • Examination of influence of sample gas pressure rep. sample gas flow
    • Examination of voltage variation influence on the measuring signal
    • Examination of influence of humidity, vibration and operational position
    • Examination of converter efficiency for NOx AMS
    • Examination of response factors for FID

    The field test

    The measuring instrument is subjected to a long term test, consisting of:

    • Examination of general device functions
    • Functional test of the measuring equipment at the beginning and end of the field test
    • Determination of the calibration range
    • Definition of the reproducibility
    • Definition of the drift behaviour at the zero and reference point in the field
    • Determination of the maintenance interval
    • Definition of the availability

    The examination is carried out with two complete sets of the measuring equipment.

    The further points are

    • Reporting with determination of the measurement uncertainty
    • Initial assessment of the AMS manufacturer´s quality management system
    • and the annual surveillance for the manufacturing process after certification.
