Certification - MCERTS for UK Particulate Matter

Defra has worked with the Environment Agency to develop a new and additional level of certification through the MCERTS scheme. This sets out the requirements for instruments to demonstrate equivalence in a representative particulate matter pollution climate for the UK and therefore receive approval from Defra for use in the UK. This certification is called "MCERTS for UK Particulate Matter" and its requirements are set out in an Annex to the Continuous Ambient Measurement Systems (CAMS) performance standard, available for download.

This new certification is needed because the MCERTS Performance Standard for CAMS does not consider whether the field testing has been undertaken in locations that are representative of the area(s) of the Member State’s territory, and therefore where monitoring will be undertaken. Being able to demonstrate the representativeness of the testing is an essential requirement of the EU Commission’s Guide to Demonstration of Equivalence.

Defra approved equipment

The table below summarises the status of particulate matter methods for use in the UK in terms of which have been approved by Defra as equivalent for use in the UK. This considers separately the instruments which were deemed equivalent by Defra and approved as equivalent based on upheld decisions predating the MCERTS for UK Particulate Matter,and instruments which are formally certified to MCERTS for UK Particulate Matter. Also included are those instruments that have MCERTS certificates but are not approved by Defra for use within the UK for particulate matter monitoring.

Notes:

1 NOTE While the TEOM 1400 PM10 analyser failed demonstration of equivalence even with linear correction for slope and offset, data can be corrected using the Volatile Correction Model and demonstrate equivalence to the Reference Method
2
NOTE FDMS 8500 units in the AURN are currently fitted with B- or CB-type dryer modules

How to apply for certification

Please contact Sira if you would like to make an application. Advice should be sought in the first instance from Sira on the design and requirements of the test programme.
