ASTM D482 Ash Content from Petroleum Products – Ash Prep
Some tests, such as atomic absorption (AA) require only the non-organic (ash producing) components of an oil or grease. This test removes all carbonaceous organic material by heating the sample, igniting and burning the vapors, and placing the remaining residue in a muffle furnace. The ash can then be further processed as needed for testing.
