IM240 tests are usually run once a month (when sufficient bookings have been made).
Please note that retesting, if required, also costs $1,265. The IM240 test is a short, transient test, developed by the US EPA, which allows high emitting light duty vehicles vehicles to be identified.
The test represents a 3.1 km route with an average speed of 47.3 km/hr and a maximum speed of 91.2 km/hr. The IM240 test certifies compliance with carbon monoxide (CO), carbon dioxide (CO2), total hydrocarbons (THC) and nitrogen oxides (NOx).
The test protocol requires vehicles to be driven on a chassis dynamometer. The vehicle is connected to emissions equipment, and a 240 second drive cycle is driven. Emissions are measured, and you will be provided with a copy of the results writing within 5 business days.
Your VASS engineer will let you know if your vehicle has passed or failed.
