Up to 25 Times Faster: Measuring the Influence of Antioxidant Additives in Spark-Ignition Fuels

The Rapid Small Scale Oxidation Stability Tester, PetroOxy, from Anton Paar, measures the induction period of spark-ignition fuels in compliance with ASTM D7525. This value can be used as an indication of the oxidation and storage stability. Compared to other oxidation and storage stability test methods, this approach uses a small sample and gives test results in a short time period (approximately 15 to 25 times faster).

For spark-ignition fuels the correlation of oxidation stability to antioxidant concentration can be determined with the Rapid Small Scale Oxidation Stability Tester, PetroOxy, to prevent the excessive use of valuable antioxidant materials and operate cost-effectively. This approach is a fast, safe and user-friendly alternative to the traditional bomb method (ASTM D525 / EN ISO 7536).
