ASTM D6331

ASTM D6331 is an industry standard that provides a method for measuring the amount of solids or particles in liquids like lubricants or fuels. Using a technique called inductively coupled plasma atomic emission spectroscopy (ICP-AES), it identifies and quantifies specific metal elements present in the sample. This helps determine contamination levels, wear, or contamination of the fluid, ensuring it meets quality and safety requirements. The test is precise and widely used in industries to monitor the condition of oils and other liquids, supporting maintenance decisions and preventing equipment failures.
