ASTM D525 - Oxidation Stability of Gasoline (Induction Period Method)


We perform testing by ASTM D525 to determine the stability of gasoline under accelerated oxidation conditions to predict whether it will form gum in storage. Gasoline fuel stored for an extended period of time can suffer from oxidation. This can cause residues and gums to form. These fuel residues and gums can cause serious problems with engines and fuel systems. The induction period may be used as an indication of the tendency of motor gasoline to form gum in storage.

We also perform oxidation stability testing by ASTM D2112ASTM D2272ASTM D2274ASTM D2440ASTM D7462ASTM D873ASTM D942ASTM D943DIN 51587EN 15751IP 142IP 388IP 40ISO 12205ISO 4623, and ISO 7536. These different test methods use different instruments or procedures or are used for certain sample types.
