Noack Tester OilLab 580

Determination of the evaporation loss of lubricating oils (particularly engine oils) as per ASTM D5800.
Procedure A uses the Noack evaporative tester equipment.
Procedure B uses the automated non-Woods metal Noack evaporative apparatus.
A quantity of 65 grams of sample is heated to a specific temperature and maintained for 1 hour while it is enclosed in a crucible, the crucible’s cover is shaped to allow a constant vacuum of 2 mbar to remove from the crucible the evaporating portion of the sample.
At the end of the test, the sample is cooled and then reweighted: the difference, reported in percentage, represent the sample’s Evaporation Loss by the Noack Method.
Method A: bath is controlled at 250°C.
Method B: the sample is controlled at 245.2°C.
