Insulating liquids. Test methods for oxidation stability. Test method for evaluating the oxidation stability of insulating liquids in the delivered state1 Scope This document describes a test method for evaluating the oxidation stability of insulating liquids in the delivered state under accelerated conditions regardless of whether or not antioxidant additives are present. The duration of the test can be different depending on the insulating liquid type and is defined in the corresponding standards (e. g. in IEC 60296, IEC 61099, IEC 62770). The method can be used for measuring the induction period,
