quality control reasons.  Jurisdictions may also choose to measure other emissions for inventory purposes.  The emissions to be measured could include:

           * total hydrocarbons (THC), parts per million as hexane (ppmh)

           * methane (CH4) ppm

           * carbon monoxide (CO), percent

           * carbon dioxide (CO2), percent

           * oxygen (O2), percent

           * nitric oxide (NO), ppm

           * particulate matter less than 2.5 micrometres nominal diameter(PM2.5), mg

           * smoke opacity, percent.

 Oxides of nitrogen should be calculated from the measured NO concentration using sample condition corrections and USEPA specified formulae.

 The DT80 transient short test has been found to be a good test for identifying high polluting vehicles.  For emissions inventory purposes results should be measured in g/sec on the DT80 and converted to CUEDC measurements using the correlation coefficient determined in NEPC Project 2.2. The CUEDC scores can than be used for inventory purposes as they reflect a better estimation of real world driving patterns.

 All equipment should be calibrated and calibration gases regularly checked in accordance with the in-service vehicle emission standards and test determined by the Australian Transport Council or successor body.

3.5.3   In-service Emissions Test Stations – Vehicle Throughput

 Jurisdictions will need to establish test stations (either fixed or mobile) that cater to the characteristics of the target vehicle group.

3.5.4   Test/Repair Procedure

 Testing of vehicles will involve the following steps.

 1. Conduct a safety check of the vehicle to determine its suitability for testing.  Faults to be considered include underinflated or unsafe tyres, fuel or fluid leaks, overheated engines and excessive smoke.  Vehicles that are unsafe for testing should be referred for repairs and re-testing.

 2. Record vehicle details including vehicle identification number, fuel type, model year, make, model, vehicle type, gross vehicle mass, tare weight, vehicle ADR category, engine displacement, number of cylinders, turbocharger, fuel system, odometer reading, testing hazards identified if any.  Depending on the computer software design and network linkages, much of this information may be automatically retrieved from registration records.

 3. Test the vehicle.

 4. Print a vehicle inspection report.  The vehicle inspection report should include maximum allowable emissions values, results for the test vehicle, a pass/fail determination and emissions values that are considered good for that age and make of vehicle.

 5. If the vehicle has failed, refer it for repair.

 6. The repair facility should issue the client with a repair report detailing the type and cost of repairs carried out.

 7. Re-test the vehicle.*

 8. Repeat steps 4 – 7 until the vehicle passes or is granted a qualified waiver (see below).

 * A jurisdiction may choose to accept evidence of vehicle repair other than re-testing such as a statement of repair from an accredited repairer.  This may be necessary in
