ASTM D7919 Standard Guide to Filter Residue Analysis (FDA) Using Manual or Automated Processes

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D7919 testing. This guide deals with removal and analysis techniques to remove and analyze deposits captured by in-service lubricant and hydraulic filters.

The purpose of this manual is to provide a guide for machine maintenance and monitoring personnel to perform filter deposit analysis as a tool to determine machine condition. Associating filter contaminants with 'normal' and 'abnormal' lubrication system operation provides early indications of a lubrication system problem related to a contaminant or component wear. Analysis of the contaminant collected within the lubrication filter element provides a means to determine the failure mode, propagation rate, and source of contamination.

The FDA differs from traditional oil analysis by sampling the filter instead of the liquid. Residues in the filter are removed for analysis. The FDA is an effective way to monitor equipment wear because wear history is efficiently captured in the filter matrix. Typically, more than 95% of all emitted metal particles larger than the filter pore size are retained in the filter.

This guide recommends techniques for removing, collecting and analyzing debris from filters to support monitoring of machine health status.
