diurnal testing.

Engine dyno for Catalytic converter aging and certification.

4 phase FTP testing. Accepted by both EPA and CARB for vehicle certification.

Our laboratory is routinely audited by CARB staff for the emissions testing programs we conduct on behalf of numerous major manufacturers. Correlation programs are maintained with both GM and Ford directly, and with the balance of the North American industry through our participation in the annual CARB correlation program. As a result, emissions data generated in support of a manufacturers’ certification will be accepted by both the USEPA and the California ARB.


Associated capabilities include Enhanced Evaporative Emissions testing, NMOG determinations, alternative fuel emissions testing, electric vehicle range testing, and hydrocarbon speciation.  SAE Coast-Downs are routinely conducted to support emissions testing of new and modified vehicles for which OEM dynamometer settings are not available.
