Testing of Diesel Exhaust Components
Raw exhaust tests are carried out to accurately measure the effectiveness of exhaust treatments to ensure emissions meet current guidelines and regulations.
There are many contributing factors to substandard emissions, including climate and conditions, and considering our often harsh Western Australian environment, it’s important to carry out these tests.
Complete Envirotest can test exhaust components on site (underground areas included), on your company premises, or anywhere in Western Australia.
Our highly skilled technicians will perform thorough testing in line with compliance guidelines and can provide either routine full fleet or single vehicle testing.
We are proud to use only the best exhaust component equipment that is routinely calibrated.
Electronic Exhaust Diesel Particulate Analysis
Measuring elemental carbon and gases from diesel emissions is a crucial part of creating a safe work environment.
As elemental carbon consists of a significant fraction of diesel particulate matter (DPM), it is considered the best indicator or marker for personal DPM measurements within vehicle exhaust emission testing.
DPM’s gas like behavior allows it to remain airborne for extended periods of time. Along with its small composition makes it easily breathable, meaning it can penetrate deep into workers lungs.
Together with a DPM analysis, we also recommend a trans-stall test. Please note, high or low idle tests are not adequate to maintain compliance.
Our trans-stall test will require an engine to be under load in low gear with a hot engine and hydraulics. The engine will need to be revving at 70 – 80% capacity for approximately 30 seconds. (Ref Management of Diesel Emissions is Western Australia Mining Operations)
Complete Envirotest most commonly follow testing procedures from the New South Wales Department of Primary Industries MDG29 April 2008 document, unless otherwise directed by the client.
Testing equipment used includes:
Kenelec AVT530 recording direct exhaust stream measurements in mg/m³, with accuracy to 1.0ug/m³ size particles.
These units have a rechargeable battery inbuilt, providing easy access to vehicles in narrow headings and allowing access to vehicles in any area of an underground mine.
TSI NPET 3795 recording direct exhaust stream measurements in particles/cm³, with an accuracy to 1.0 µm size particles.
Exhaust Gas Emission Testing
Complete Envirotest carries out Exhaust Gas Emission testing using the latest Dräger technology that complies with the Mines Safety and Inspection Regulations 1995.
It’s important to carry out this testing to ensure your engines are adhering to standards set to control air pollutants, while also providing safe equipment for workers.
Our technicians carry out extensive testing via a stringent process, collating the measurements of four gases including:
CO – Carbon Monoxide
NO – Nitric Oxide
NO2 – Nitrogen Dioxide
NOx (NO + NO2) – Nitrogen Oxide
To comply with Department of Mining, Industry Regulation and Safety (DMIRS), all your underground diesel machinery is required to be tested at intervals no later than:
250 hours of machine operation
1-month intervals for machinery without an hour meter
After large maintenance repairs to engines
At the request of a Mines Inspector
