This is an ASTM International Standard Test Method for the analysis of wear metals and contaminants in used oil. The Spectroil family of oil analysis spectrometers meet and exceed the requirements of this specification. Copies of the complete method are available from the ASTM web site at http://www.astm.org. The full title and partial scope of the method is listed below:
Standard Method for Determination of Wear Metals and Contaminants in Used Lubricating Oils or Used Hydraulic Fluids by Rotating Disc Electrode Atomic Emission Spectrometry
- 1. Scope
- 1.1 This test method covers the determination of wear metals and contaminants in used lubricating oils and used hydraulic fluids by rotating disc electrode atomic emission spectroscopy (RDE-AES).
- 1.2 This test method provides a quick indication for abnormal wear and the presence of contamination in new or used lubricants and hydraulic fluids.
- 1.3 This test method uses oil-soluble metals for calibration and does not purport to relate quantitatively the values determined as insoluble particles to the dissolved metals. Analytical results are particle size dependent and low results may be obtained for those elements present in used oil samples as large particles.
- 1.4 The method is capable of detecting and quantifying elements resulting from wear and contamination ranging from dissolved materials to particles approximately 10 µm in size.
