NPL Environmental Measurements Group
(EMG) organises a range of proficiency testing (PT) schemes in the stack
emissions measurement 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 schemes in operation; Particulate, Gas Measurement and Calibration Gas. The Gas Measurement and Calibration Gas
schemes are run bi-annually with measurements conducted at NPL. The Particulate
scheme is run bi-annually with test items sent to participants.
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 competently perform tests and measurements
for which accreditation is held. 'It is UKAS policy that all accredited
testing laboratories shall participate in PT/ILCs where such schemes are
available and relevant to their scope of accreditation'. For
further guidance on UKAS policy in relation to proficiency testing see
TPS 47 'UKAS Policy on Participation
in Proficiency Testing'. Participation in a proficiency testing
scheme for stack monitoring is also a requirement of the UK Environment
Agency's Monitoring Certification Scheme (MCERTS).

Schedules for the
