The induction period may be used as an indication of the tendency of motor gasoline to form gum in storage. It should be recognized, however, that its correlation with the formation of gum in storage may vary markedly under different storage conditions and with different gasolines.
Область применения1.1 This test method covers the determination of the stability of gasoline in finished form only, under accelerated oxidation conditions. (Warning
Note 1—For measurement of oxidation stability of gasoline by measurement of potential gum, refer to Test Method D873, or IP Test Method 138.
Note 2—The precision data were developed with gasolines derived from hydrocarbon sources only without oxygenates.
1.2 The accepted SI unit of pressure is the kilo Pascal (kPa), and of temperature is °C.
