PG5/2 Emissions Testing

NWSS offer fully MCERTS accredited stack emissions monitoring from cremator flues to satisfy the requirements in process guidance Note PG5/2. This includes the current 2004 document and the proposed testing in the revised guidance note.

We are one of few companies who can offer both sampling and analysis to UKAS and MCERTS accreditation.  We have our own UKAS accredited laboratories, enabling us to give accurate and prompt results to our clients.  Our UKAS schedule includes the following monitoring to satisfy the annual testing requirements from cremator flues:

Routine monitoring (cremators pre 2006):

• Total Particulates (BS EN 13284-1 or BS ISO 9096)
• Hydrogen Chloride (BS EN 1911)
• Carbon Monoxide (BS EN 15058 (superceded ISO 12039))
• VOC's (BS EN 12619/BS EN 13526)
• Oxygen (BS EN 14789 (superceded ISO 12039))

Additional monitoring if required combustion condition are not met, and/or for cremators post 2006:

• Mercury (BS EN 13211)
• Dioxins & Furans (BS EN 1948)                         

Results would be reported at reference conditions of 273K, 101.3kPa, 11% oxygen on a dry basis.

For dioxin and furan testing it is recommended that testing is performed over 2-4 cremations in order to meet detection limits required. NWSS laboratory can achieve very low detection limits for these tests so with regulator permission this could be carried out over 1 cremation.

In addition to the routine testing we can also provide calibration functions for continuous particulate and gaseous analysers via manual sampling. For particulate analysers 3 to 5 tests would be taken to derive the function.

NWSS operates one of the largest and most experienced air monitoring teams.  We currently employ 16 air quality scientists, most of whom are qualified to MCERTS Level 2 with all technical endorsements.

The air emissions team operates from two sites; Newcastle upon Tyne in the North East, and Cwmbran in South Wales, offering Ireland and UK coverage.  An extensive range of analyses is carried out at our in-house UKAS accredited laboratory in Newcastle, enabling us to give accurate and prompt results to our clients.  We also believe that chain of custody of samples is paramount and by providing customers with both sampling and analysis without the need for sub-contracting to other laboratories, we are confident we can offer a robust chain of custody.
