Emission measurement guidance and training

Promoting good practice in emissions measurements  

NPL provides training and consultancy on source emissions measurements. We are on the Management Board of the Source Testing Association, with whom we organise proficiency testing schemes. We have been involved with the creation of the Environment Agency's MCERTS scheme and we offer guidance on the implementation of CEN standards, e.g. EN 14181.

EN 14181

Scientists from NPL represent the UK on CEN committee working groups, which draw up standards for emission measurement in Europe.

We have written a Guidance Document on the implementation of EN 14181, for the Irish EPA. 

We have also developed uncertainty budgets for the standard reference methods (SRMs) required for the implementation of EN 14181. These are available for all stack emissions measurements teams to use, although users should validate their own calculations.

Continuous Emissions Monitor (CEM) Testing

NPL has ISO 17025 accreditation for the testing of CEMs, required to gain MCERTS certification. Our unique Stack Simulator is used to test new measurement methods and protocols and we have fully accredited stack emissions monitoring teams. For more details, please follow the links:
