Evaporative Emissions Testing

Vehicle evaporative emissions testing services from SGS – ensure your manufacturing standards meet air quality and environmental requirements.

Limiting emissions and reducing air pollution attributed from vehicles is not only an environmental obligation we place on our own organizations but also a regulatory and legislative standard for vehicles driven on our roads. Our suite of advanced evaporative emissions testing systems equip you with the quality testing services to meet standards set by regulatory agencies.

What are the advantages of using SGS for your evaporative emission testing needs?

Our evaporative emissions testing services provide you:

• Testing of fuel emissions of a vehicle that may not be related to the exhaust
• Testing that measures and reports data for agency and other regulations such as the EPA, CARB, and CFR Title 40 Part 86
• Use of reporting data that assists with the evaluation and performance of vehicles, and other emission-related regulations
• Achieve environmental quality standards to communicate the environmental quality of your products
• Assist with identification of engine and vehicle technology that may be used for future product development

Unrivaled expertise in the design and efficiency of testing evaporative vehicle emissions

Our evaporative emissions testing systems include:

• Sealed Housing for Evaporative Determination (SHED) drive-in test chambers designed to create conditions specified by the EPA and CARB
• Four Variable Temperature SHED (VT SHED) fixtures, meeting evaporative emission testing requirements outlined in CFR Title 40 Part 86
• Onboard Refueling Vapor Recovery Determination (ORVR) testing to simulate actual refueling activity to measure the loss of gasoline vapors that might escape the vehicle’s ORVR systems during the refueling activity
• Running Loss Test performed to measure any evaporative emissions (hydrocarbon fuel vapors) given off during vehicle operation (Point Source Method)
• Evaporative Canister Load Station capable of loading standard 2-day and 3-day loadings as well as customer specified loading rates and durations
• Custom test design, implementation, and report generation with engineering analysis
• Long duration diurnal cycles (15 days) for fuel RVP studies and breakthrough analysis
• Speciation of compounds released into the SHED via Photo acoustic infrared analyzer
• Alternate fuels testing
