ASTM D4898 - Insoluble Contamination of Hydraulic Fluids by Gravimetric Analysis

We perform lubricants quality testing by ASTM D4898 to measure the particulate contamination in hydraulic fluids by filtration.  This test method indicates and measures the amount of insoluble contamination in hydraulic fluids. Minimizing the levels of insoluble contamination in hydraulic fluids is essential for the satisfactory performance and long life of equipment. Insoluble contamination can not only plug filters but can also damage functional system components, resulting in wear and eventual system failure.
