Octane Testing
Octane testing laboratories.
Intertek provides full gasoline octane rating and testing through a global network of laboratories. The octane labs use CFR (Cooperative Fuel Research) engines and test to ASTM and other industry and regulatory protocols. Octane tests measure gasoline characteristics related to engine knocking. Intertek octane labs measure gasoline samples from refineries, storage facilities, storage tanks and pipelines for octane ratings and other gasoline fuel properties.
