Evaporative Emission Testing

Permeation Testing
Helium Leak TestSterling Performance Testing Service provides fuel system evaporative emission testing utilizing _Sealed Housing for Evaporative Emission Determination (SHED) testing methods.

Permeation Testing Experts:
Your results can be trusted because our professional staff has years of experience and are trained in handling components for evaporative emission testing so your parts are not contaminated with outside hydrocarbons.

Component and System Testing / Large or Small:
When it comes to evaporative emissions, permeability and testing hydrocarbons, we help customers by testing permeation on a per part basis and knowing the best way to test components vs. the system. Components tested individually get highly accurate results per piece, so you can identify which parts were out of specification, if any. This way you don’t have to scrap an entire batch or design if you had just one bad part.  We save you money.

We test individual components and entire fuel systems. Even full size vehicle bucks can be evaluated for evaporative emissions.  We work with clients to develop appropriate evaporative emission-testing protocols and test to customer requirements. You’re guaranteed precision test results.

Recognized by the EPA:
The quality, reliable, and repeatable of our data has allowed us to test for and be recognized by the Environmental Protection Agency for Evaporative Emission Testing.
