Revised TGN M20 V2.2 June 2010
Posted on: June 10, 2010
Version 2.2 of EA Technical Guidance Note (Monitoring) M20 has just been released by the Environmental Agency (England & Wales). Three of the key changes that will affect the initial planning of BS EN 14181 testing regimes are:
- From the beginning of 2011, all test laboratories used for performing BS EN 14181 QAL 2 and AST assessments must be accredited by UKAS to BS EN 14181. Environmental Compliance Ltd have already undergone their assessment and will be in the position to be able to offer this service from the start of 2011 as required;
- Organisations undertaking Functionality Tests, as outlined in Section 3.4 and Annex 1 of the Technical Guidance Note, must be able to provide evidence that they can meet the quality assurance and control requirements as stated in the Technical Guidance Note. This clause stresses the importance of good co-operation between the Test House, the Equipment Suppliers / Instrument Manufacturers (sometimes tasked with the functionality aspects of the standard) and the End Users. Functionality Tests should not be undertaken more than 1 month previous to the parallel measurements, unless the operator can justify the reasons to the regulator (i.e. be able to demonstrate that the Analyser System(s) or processes have remained stable and under control).
- BS EN 15259 requirements and the corresponding MID document have been inserted into the Technical Guidance Note to replace ISO 10396. Under the requirements of BS EN 15259, corresponding Method Implementation Document (MID15259) and as stated in Technical Guidance Note M1, Operators are required to prove that the gaseous species are sufficiently mixed, i.e. no difference in pollutant concentration across the duct. If the pollutants are adequately mixed they are considered “homogenous”.
If a homogeneity test has not been carried out at a location, it will be detailed in the report as a non-conformity and it will be up to the regulatory authority to decide what course of action they will take against the process operator if the work is not performed.
The above are just three of the seventeen changes that have been made to the Technical Guidance Note as an update to version 2.1 issued in September 2008. To download a copy of the revised document, please click here.
