ASTM D6375-09(2014) PDF

Scope: 5.1 This test method is a safe and fast alternative for determination of the Noack evaporation loss of a lubricant.

5.2 The evaporation loss of a lubricant is important in the hot zones of equipment where evaporation of part of the lubricant may increase lubricant consumption.

5.3 Some lubricant specifications cite a maximum allowable evaporative loss.

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 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.

1.2 The evaporative loss determined by this test method is the same as that determined using the standard Noack test methods.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
