This International Standard describes three test methods using the same apparatus for evaluating the oxidation stability of mineral insulating oils and of hydrocarbon-based insulating liquids. It comprises four sections as follows:
Section 1 describes the following items common to the three methods:
- the equipment and reagents;
- the cleaning of the glassware;
- the preparation of the catalyst and of the insulating liquid sample to be tested;
- the determinations on the oxidized insulating liquid.
Section 2 - Method A describes a method for evaluating the oxidation stability of unused uninhibited mineral insulating oils under accelerated conditions.
Section 3 - Method B describes a method for evaluating the oxidation stability of unused inhibited mineral insulating oils under accelerated conditions.
Section 4 - Method C describes a method for evaluating the oxidation stability of unused uninhibited and inhibited hydrocarbon insulating liquids under accelerated conditions.
