DIN EN 15267

For an optimized environmental protection, reliable values from continues measurement units are the most important criterion. The European regulation allowed in the mandatory area only DIN EN 15267 certified automated measuring systems for the continuous measurements of air pollution. Regular certification procedures for QAL1-certificates only still established in UK and Germany. But outside the European Union a QAL1-certificate facilitates the entrance in international markets.


The QAL1-certification for automatic emission measuring instruments is accomplished on the basis of DIN EN 15267 sheets 1 to 3 and is divided into the following work procedures:

  • Laboratory test
  • Field test
  • Auditing the manufacturer’s quality management system
