IP 388 - Oxidation Stability of Middle-Distillate Fuels

We perform testing by IP 388 to measure the oxidation stability of diesel and other middle distillates by bubbling oxygen through the heated sample for 16 hrs. This test measures the inherent stability of middle distillates (e.g., diesel fuel) under oxidation conditions.  The test is performed by placing a measured quantity of fuel in a test tube and bubbling oxygen through the liquid while heating the liquid to 95°C for 16 hours.  Following the exposure, the liquid is filtered and the level of insoluble material is measured. 

This test simulates storage of diesel fuel for one year.  A result of less than 1.5 mg/100 ml is generally considered acceptable.

We also perform oxidation stability testing by ASTM D2112, ASTM D2272, ASTM D2274, ASTM D2440, ASTM D525, ASTM D7462, ASTM D873, ASTM D942, ASTM D943, DIN 51587, EN 15751, IP 142, IP 40, ISO 12205, ISO 4623, and ISO 7536. These different test methods use different instruments or procedures or are used for certain sample types.
