Abstract:
Gum is the denoted term for when the hydrocarbons present in fuels react with absorbed atmospheric oxygen and with each other forming resinous, polymeric, and non-volatile materials with a high molar mass. Over time, fuels have the tendency to develop gum content. Gum, when dissolved in gasoline or aviation fuel, can affect engine performance of equipment, which can be inconvenient and especially dangerous, specifically in aircrafts. Koehler Instrument Company’s newly released K33900 Existent Gum Evaporation Bath determines the gum content in aircraft turbine fuel and motor gasoline according to ASTM D381. This test method specifically covers aviation fuels, motor gasoline, and volatile distillates in their finished form in order to determine the preexistent gum content. The test evaluates the propensity of a fuel to form gum as well as measuring the amount of contaminants, typically ones with high boiling points, within a sample. The new K33900 instrument includes benefits such as a redesigned safety top assembly, digital flowmeters, advanced air flowmeters, built-in pressure regulators, and microprocessor programmable high accuracy temperature control. These features allow for smooth and safe testing with few complications. This poster discusses the latest advances in instrumentation for ASTM D381.
