Gasoline Testing & Certification
We can perform all of the tests required for the ASTM D4814 specification for gasoline including octane using CFR octane engines. We can also perform all of the tests required to calculate EPA Complex VOC reduction model, which is relevant in EPA-designated ozone nonattainment areas.
Gasoline is a blend of volatile liquids that breaks down over time. Oxidation, or the reaction of the liquid with oxygen, can lead to the formation of solid contaminants. Evaporation can leave a sticky residue, known as “gum” or non-volatile residue. These can cause clogged fuel filters and fuel injectors and can damage fuel pumps and carburetors. Ethanol (alcohol) is commonly blended with gasoline. Gasoline-ethanol blends are particularly likely to absorb moisture and can separate into two phases (a hydrocarbon phase floating on top of a water-alcohol phase, similar to the separation of oil and water). Phase separated gasoline is unusable because the water/alcohol layer will plug filters, cause corrosion and damage engine components and the gasoline layer doesn’t meet octane specifications.
We perform gasoline testing for refineries, pipelines, trucking companies, gas stations, car dealerships, insurance companies, and individual vehicle owners. While we can perform the full slate of testing for formal ASTM D4814 certification, we work with all of our customers to choose the tests that best meet their needs. Contact us today to discuss your own fuel testing options.
