consider the use of screening testing to identify vehicles suspected of poor performance that need to be subjected to the full in-service emissions test.  Screening testing could involve the use of mobile briefcase and remote sensing systems or visual inspections during routine vehicle examinatations. The use of these technolgies may allow for more effective vehicle selection, improve program efficiency and allow effective communication to the owners of gross polluting vehicles.

3.3   Emission Pass/Fail Levels

 In implementing a vehicle test and repair program, a jurisdiction should nominate the pollutants it wishes to target.  These should include particles and visible smoke measured according to the vehicle emission standards and test determined by the Australian Transport Council or successor body.

 A jurisdiction may also choose to target NOx emissions.

 The pass/fail levels will be the appropriate in-service emissions standards as specified by the Australian Transport Council or successor body.

 The emissions standards are specified in mass of pollutant emitted per kilometre travelled per vehicle mass, i.e. in grams per kilometre per tonne.  Vehicle test results should therefore be reported in grams per kilometre per tonne and grams per kilometre (for use in calculating emissions inventories).

3.4   Obliging Vehicles to be Tested

 To effectively implement test and repair programs, jurisdictions must identify a means of compelling or encouraging vehicles to be submitted for testing.  To be effective the method should have a statutory basis.  The method most commonly used in international programs is to require targeted vehicle owners to submit their vehicles for testing and repair before the vehicle registration is renewed.  However, with a mobile dynamometer other options including random roadside testing can be used effectively.

3.5   Testing Regime and Infrastructure

3.5.1   In-service Emissions Test

 The in-service emissions test to be employed in a diesel vehicle test and repair program is the test determined by the Australian Transport Council or successor body. At the date of commencement of this Measure, this is the DT80 transient short test.  The protocol for conducting the test is determined by the Australian Transport Council or successor body.  Vehicles should be tested using the fuel present in the vehicle tank when it is submitted for testing.

3.5.2   In-service Emissions Test Equipment

 Required equipment specifications are detailed in the in-service vehicle emission standards and test determined by the Australian Transport Council or successor body.

 The target pollutants may not be the only emissions measured during a test and repair program.  Measurements of carbon dioxide and oxygen are required for 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
