Industrial processes which emit to atmosphere do so under permit granted by the Environment Agency or the Local Authority. The permit would define the permissible limits for the various pollutants emitted by the process.
Some processes may have continuous emissions monitoring systems (CEMS) installed providing real time data on the emissions whilst other processes would be subject to periodic testing. In both cases independent testing of emissions is a requirement of the permit. The company undertaking third party testing is required to have accreditation by the United Kingdom Accreditation Service (UKAS) to ISO 17025 and CEN/TS 15675 and also be accredited by UKAS under the Environment Agency Monitoring Certification Scheme (MCERTS). Personnel who conduct the tests must be accredited to the scheme.
CES Environmental Instruments Ltd has held UKAS Accreditation for many years and gained MCERTS Accreditation shortly after the scheme was introduced. Many of our engineers have attained MCERTS Level 2 status (team leader) with the full range of technical endorsements. (TE1, TE2, TE3 and TE4).
The current schedule defining the substances and parameters for which we are accredited is to be found on the UKAS website, click here.
The substances include the following: -
|Particulates ||Hydrogen Fluoride|
|Water Vapour ||Metals|
|Sulphur Dioxide ||Carbon Dioxide|
|Polycyclic Hydrocarbons (PAHs) ||Propane|
|Dioxins and Furans ||Oxides of Nitrogen|
|Total Mercury ||Total Organic Carbon (TOC)|
|Ammonia ||Volatile organic carbon (VOC)|
|Halogens & Halides ||Oxygen|
|Hydrogen Chloride ||Pressure, temperature and velocity.|
Our instruments and procedures are compliant with British Standards and MCERTs requirements. UKAS Accreditation has been achieved for our use of the latest Fourier Transfer Infra-Red (FTIR) analysers enabling on site gas analysis to be carried out more efficiently and cost effectively.
Standards applicable to the monitoring of various substances are listed below:
