K10400 Oxidation Stability of Fuels, Liquid Baths


 

Test Method
Provides an indication of the tendency of gasoline and aviation fuels to form gum in storage. The sample is oxidized inside a stainless steel pressure vessel initially charged with oxygen at 100psi (689kPa) and heated in a boiling water bath. The amount of time required for a specified drop in pressure (gasoline) or the amount of gum and precipitate formed after a specific aging period (aviation fuels) is determined.

Features and Benefits
• Conforms to ASTM D525, D873, ISO 7536 and related specifications

• Available in two, four or six-unit configurations

• Choice of water or solid block heating baths

• Oxidation pressure vessel incorporates burst disk assembly


 

K10400 Oxidation Stability of Fuels, Liquid Baths
Two different models, both equipped with low liquid-level controllers in accordance with the latest ASTM specifications. Two-unit water bath can be flush mounted in a table top if desired, and is equipped with an overflow standpipe/drain to maintain the proper depth when the pressure vessels are inserted, and a plated brass reflux condenser to minimize evaporation loss. The four/six-unit model can be used with water or oil as a bath medium, and has microprocessor temperature control that provides quick temperature stabilization without overshoot. Dual LED displays provide setpoint and actual temperature values in °C/°F format. A built-in overtemperature control circuit interrupts power should the bath temperature exceed a programmed cut-off point. Both models feature double-wall insulated construction with stainless steel tanks, support racks and port covers. Order thermometer separately. The four/six unit model can be ordered with interchangeable racks for performing the ASTM D942, ASTM D323 and D1298 test methods. Please contact your Koehler representative for additional information.

Communications software (RS232, etc.) ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information.
