Stack Testing
Stack emission monitoring is carried out by a highly skilled and experienced monitoring team, including
Level 1 & 2 MCERTS-certified personnel, holding the following technical endorsements:
- TE1 - particulate monitoring by isokinetic techniques;
- TE3 - for gases/vapours by manual techniques; and
- TE4 - gases/vapours by instrumental techniques
It is a condition of holding MCERTS-certification that personnel are required to comply with the Health and Safety requirements set out in the Environment Agency document "M1". As a result, sampling must be carried out from permanent or temporary (heavy-duty scaffold) platforms at all times (except in extremely limited circumstances).
Typical methods used include:
- ISO 10780 Duct velocity and volume flowrate
- BS EN 13284 Particulates from 0-20mg/m3 (manual method)
- BS ISO 9096 Particulates from 20-1000mg/m3 (manual method)
- BS EN 12619 Organic compounds at low concentrations (instrumental method)
- BS EN 13526 Organic compounds at high concentrations (instrumental method)
- BS EN 13649 Specific organic compounds (manual method)
- BS EN 14789 Oxygen
- BS EN 14790 Water vapour
- BS EN 14791 Sulphur Dioxide
- BS EN 14792/ISO 10849 Oxides of Nitrogen
- BS EN 15058 Carbon monoxide
- BS EN 1911 Hydrogen chloride (manual method)
- ISO 15713 Hydrogen fluoride (manual method)
- BS EN 14385 Metals (manual method)
- MDHS 25/3 Isocyanates
- PG 4/1(04) Oxides of Nitrogen from Metal Treatment Processes
NEMS is a
SIRA-approved MCERTS training provider for the
"hazard identification and risk assessment relating to stack emission monitoring" course.
This course must be attended by MCERTS personnel every five years. Click

Dispersion Modelling
NEMS is able to complement the monitoring of
source emissions with
computer modelling of the dispersion of
pollutants to assess the effects of emissions on the surrounding environment.
Staff have experience of both UK & US modelling software, including:
ADMS
ADMS Screen
AerMod
ISC Screen
ISCLT/ST
DMRB
Fugitive Dust Model
