Proficiency Testing Schemes
Proficiency Testing (PT) schemes operate by providing
participating laboratories with test samples for analysis.
Laboratories analyse the test samples, preferably as part of their
normal routine, and reports the results to the scheme organisers.
They are then provided with a report showing how closely their
results agree with the accepted values. Regular participation in a

HSE Testing and Monitoring PT Schemes in
AIR PT, a collaboration between HSE and LGC, is a new
International PT scheme for laboratories involved in air quality
The scheme combines HSE's WASP and LGC's STACKS schemes,
providing an integrated PT that is specifically designed for
laboratories performing chemical analysis of air monitoring
The scheme is run by LGC and is supported by the technical
expertise at HSE, ensuring the test samples are as close as
possible to those routinely analysed by laboratories (ambient,
indoor, workplace air and stack emissions).
For more information, please click on the AIR PT balloon logo
below. Here you can download the application form and scheme
description, which will provide comprehensive details of the
available samples and the dates for each round of the scheme.
