ASTM D5800 Noack Evaporation Loss Testing for Lubricating Oils
ASTM D5800 is used to determine evaporation loss of lubricating oils. It is determined by four procedures and reported as percent total loss. Procedure A & C and B & D provided in ASTM D5800 test method produce equivalent results, thus a correction factor is utilized to convert between the two sets of procedures based on the fluid type.

Overview
ASTM D5800 determines the evaporation loss of lubricating oils using the Noack method by measuring the mass loss after exposure to high temperature under controlled airflow or vacuum conditions. It quantifies the tendency of oil to volatilize, which directly impacts oil consumption, viscosity stability, and emission characteristics in service conditions.
This method is critical for evaluating high-temperature performance of engine oils and lubricants, especially in applications where thermal stability and low volatility are required. By providing precise evaporation loss data, ASTM D5800 helps manufacturers optimize formulations, improve efficiency, and ensure compliance with performance specifications for modern lubrication systems.
