Stack & Other Testing Methods utilised by Aspen Environmental Ltd
UKAS Accreditation:
UKAS is the United Kingdom Accreditation Service, and administers Aspen's accreditation to BS EN ISO 17025:2005 General requirements for the competence of testing and calibration laboratories . UKAS perform audits on Aspen's performance, both on our own, and on sites where Aspen is involved in testing, to ensure the ongoing efficiency and competance of the organisation. UKAS accreditation ensures that all testing and analysis is controlled to the same standard, and thereby ensures the veracity of the results.
MCerts Accreditation:
The Environment Agency's Monitoring Certification Scheme (MCerts) consists of a series of parts of which two are relevant to Aspen. The first is a personal training and endorsement scheme, to which all our emissions testing staff belong. The second is a company scheme, which is effectively an extension to the UKAS accreditation scheme above, and also administered by UKAS. The MCerts scheme is currently required for all testing on sites regulated by the EA, and involves extra work over and above BS 17025 such as the preparation and use of site specific reviews and protocols, and a new extensive reporting requirement.
Aspen Environmental Ltd undertakes testing to MCerts & UKAS standards, as well as some testing which while currently not accredited, is conducted within our quality system.
Where the extra expense (to the client), of testing & reporting to the MCerts standard is not required (e.g. for a local authority regulated schedule A2 or B process), Aspen recommends that in the best interest of the client, the MCerts standard be waived, and testing should follow the UKAS accredited protocols.
The following list is of tests undertaken by Aspen Environmental Ltd, and their quality status.
