Standard Practices
In addition to monitoring oil contamination and wear metals, modern usage of OA includes the analysis of the additives in oils to determine if an extended drain interval may be used. Maintenance costs can be reduced using OA to determine the remaining useful life of additives in the oil. By comparing the OA results of new and used oil, a tribologist can determine when an oil must be replaced. Careful analysis might even allow the oil to be "sweetened" to its original additive levels by either adding fresh oil or replenishing additives that were depleted.
Oil analysis professionals and analysts can get certified in compliance with ISO standards by passing exams administered by the International Council for Machinery Lubrication (ICML).

Famous quotes containing the words standard and/or practices:
“Neither I nor anyone else knows what a standard is. We all recognize a dishonorable act, but have no idea what honor is.”
—Anton Pavlovich Chekhov (1860–1904)
“Such is the art of writing as Dreiser understands it and practices it—an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.”
—H.L. (Henry Lewis)
