The Particulate and Gases proficiency testing schemes are scheduled to take place in 2023. Registration is will be open soon for both schemes.
Proficiency Testing for the Stack Emissions Measurement Industry
NPL’s Emissions and Atmospheric Metrology Group organises a range of UKAS accredited (0016) proficiency testing (PT) schemes in the stack measurements area. NPL is a global leader in the provision of proficiency testing schemes; schemes are available in the areas of stack emissions, environmental radioactivity and gas metrology.
There are three stack emission PT schemes in operation:
- Particulate Measurement
- Gas Measurement and Gas Cylinder for Portable Emissions Measuring Systems
The Particulate scheme is run bi-annually in May and September with test items sent to participants.
The Gas Measurement and Gas Cylinder scheme is scheduled for June 2023, subject to sufficient participants registering. Participants will attend the NPL Teddington site over two days to measure the cylinders and NPL stack simulator. Setup takes place between 4-6pm on the first day, before performing the required measurements on day two.
A PT scheme provides a way of assessing the performance of laboratories by a series of regular inter-laboratory comparisons. Proficiency testing schemes are used by laboratory accreditation bodies as part of the process to assess the ability of laboratories to perform tests and measurements competently for which accreditation is held. UKAS policy on proficiency testing is laid out in their document: TPS 47- : TPS 47 'UKAS Policy on Participation in Proficiency Testing'. The policy states that “all accredited testing laboratories shall participate in PT/ILCs where such schemes are available and relevant to their scope of accreditation”. Participation in a proficiency testing scheme for stack monitoring is also strongly advised by the UK Environment Agency's Monitoring Certification Scheme (MCERTS).
NPL is working with the UK and Irish Regulators (EA, SEPA, NRW, DAERA-NI & EPA) to set up a steering and oversite committee to ensure that the PT Scheme is relevant to their regulatory requirements.
Schedules for the current rounds of each of the schemes can be found in the relevant section on the website.
