Standard Test Method for Oxidation Stability of Gasoline (Induction Period Method)

1.1 This test method covers the determination of the stability of gasoline in finished form only, under accelerated oxidation conditions.

Note 1-This test method is not intended for determining the stability of gasoline components, particularly those with a high percentage of low boiling unsaturated compounds, as these may cause explosive conditions within the apparatus. However, because of the unknown nature of certain samples, the bomb assembly shall include a safety burst-disc in order to safeguard the operator. Note 2-For measurement of oxidation stability of gasoline by measurement of potential gum, refer to Test Method D-873, or IP Test Method 138.

1.2 The accepted SI unit of pressure is the kilo Pascal (kPa); pound per square inch (psi) values are provided in parentheses for information.
