In-Service Oil Monitoring | ASTM Standard to measure remaining level of phenolic compounds in lubricating oils

A proposed ASTM International standard will help determine the remaining level of phenolic compounds in lubricating oils. ASTM’s committee on petroleum products, liquid fuels, and lubricants (D02) is developing the proposed standard, which describes a trend analysis process using Fourier transform infrared (FT-IR) spectrometry.

Phenolic compounds are widely used in engine, hydraulic, and other types of oils to protect against oxidation. The proposed standard (WK73062) will help machine operators recognize severe operating conditions before base oil degradation and machinery failure.
