Envirocare is delighted to announce that we have added BS EN 14181:2014 Stationary Source Emissions – Quality assurance of automated measuring systems to our UKAS schedule.

BS EN 14181 is a European standard that describes the quality assurance procedures needed to assure that automated measuring systems, installed to measure emissions to air, can meet the measurement uncertainty requirements set out in legislation.

Industrial plant operators have a responsibility to keep their emissions monitoring systems working and in good condition. Gaining BS EN 14181 means Envirocare can now support large combustion plants and waste incinerators to ensure they meet the required criteria demanded by law.

What is BS EN 14181?


BS EN 14181 specifies procedures to establish three different quality assurance levels (QALs) and an Annual Surveillance Test (AST). It covers the approval, calibration, testing and monitoring of measuring systems to ensure Continuous Emissions Monitoring equipment (CEMS) meet the requirements of legislation.

The different stages are as follows:

  • QAL 1 – Analyser suitability and assessment of CEMS equipment for its measuring task
  • QAL 2 – The validation of the CEMS following its installation (In-situ calibration)
  • AST – Similar to QAL 2 but carried out on a smaller scale (5 tests over 1 day, rather than 15 tests over 3 days). These are Standard Reference Method (SRM) Parallel tests by an ISO 17025 UKAS-MCERTS test house to validate calibration from QAL 1
  •  QAL 3 – The on-going monthly check of operational performance and accuracy of the CEMS.
    The overall aim is to reduce industrial air emissions by ensuring that Continuous Emission Monitoring Systems are functioning to a high-quality and reliable standard.

John Healey, Managing Director of Envirocare, is delighted with the news:

“We are thrilled to be MCERTS and UKAS accredited for BS EN 14181. This will allow Envirocare to better support our clients and will enable us to provide a high-quality service to a wider range of clients”
