This standard specifies the closed cup aging method for the determination of phosphoric acid ester anti-bunker oil, which is suitable for the determination of this type of aging test. The aging test of Miscellaneous ester oil can be referred to the implementation of this method. The cited standard documents include GB 264, GB/T 601, GB/T 5231, GB/T 7600, GB/T 28552 and DL/T 429.7, which involve the determination of acid value of petroleum products, the preparation of standard titration solutions for chemical reagents, the grades and chemical compositions of processed copper and copper alloys, the determination of Moisture content of transformer oil and turbine oil in operation, the determination of acid value of transformer oil, turbine oil, and the determination of oil sludge precipitation for electric power. The summary of the method includes loading the specimen and copper catalyst into a closed container, placing them in a thermostatic drying oven for aging 164 hours, testing the acid value and sludge precipitation before and after aging, and the anti-aging performance of the specimen is expressed by the increase in acid value and sludge precipitation during aging. Instrument requirements include conical flasks with abrasive plugs and thermometers.
