1.1 This test method covers the procedure for determining the Noack evaporation loss of lubricating oils using a thermogravimetric analyzer test (TGA). The test method is applicable to base stocks and fully formulated lubricant oils having a Noack evaporative loss ranging from 0 % to 30 % by mass. This procedure requires much smaller specimens, and is faster when multiple samples are sequentially analyzed, and safer than the standard Noack method using Wood’s metal.
