This method is for determining the induction period of gasolines. It is useful as a control test and will show responses of gasolines to inhibitors. The method does not give the same numerical induction periods as ASTM Method D 525 because of differences in construction of the pressure vessel, the amount of oxygen in the pressure vessel, heat transfer, surface area of gasoline to be oxidized, the sample volume, and the type of bath used to heat the vessel. The results, however, are parallel but may be somewhat higher and this method is faster and more convenient to perform.
