The Air Testing Laboratory

FAQs about the air testing laboratory

• What does the air testing laboratory consist of?

  Our air testing laboratory consists of:

  • More than ten mobile laboratories for accredited measurements of air pollution in Denmark, Sweden, and Norway respectively.
  • A gas mixing bench for checking and calibrating gas monitors
  • Equipment for check and calibration of gas meters, thermal sensors, pressure gauges, and flow meters
  • An odour testing laboratory
  • A sensor testing laboratory
  • A fuel testing laboratory for analysis of collected air pollutant samples 

   
• How can I make sure that my AMS surveillance equipment fulfils the environmental permits and relevant standards?
  You need to perform accredited parallel measurements in the chimney.
  
  Having acquired the measuring equipment, you must perform a QAL2, which includes a functional test and 15 parallel measurements spread over 3 days. You need to process the data according to the EN 14181 standard. The calibration function obtained from the data processing must be used for correction of the measurement results from the surveillance equipment before you report the results to the environmental authorities.
  
  The data processing also includes a test of the measurement capability of the measuring equipment. The subsequent years, you must perform an AST consisting of a functional test and 5 parallel measurements spread over one day. When performing the AST, you among other things check whether the calibration function is still valid. Every fifth year or if the AST test is not passed, you will need to perform a QAL2 instead of an AST.
  
  It is particularly important to plan and perform the QAL2 and AST carefully to ensure that you pass the test and that you calculate a reliable calibration function. For certain parameters like e.g. CO2 and NOX, you must pay levies and taxes of the measurement results, and therefore it is particularly important to ensure reliable measurements.
