Scope

1.1 This test method covers the determination of wear metals and contaminants in used industrial oils by sweeping flat electrode atomic emission spectroscopy (SFE-AES).2 1.2 Industrial oil includes lubricant oil, gear box oil, hydraulic fluid, compressor oil, turbine oil, synthetic oils, and other petroleum oils. 1.3 Method working range for every element is evaluated by equations in 15.2.1 and tabulated in Table 6. 1.4 Though this technique is designed to analyze nonsuspended particles in lubricant samples, the precision statements published here were established solely from homogeneous oil samples per Practice D6300 requirements. Nonsuspended particles, which are inhomogeneous by nature, were not sampled and evaluated for deriving precision statements for this test method (see Annex A1). 1.5 This test method provides a quick indication for abnormal wear and the presence of contamination in new or used industrial oils by immediately reporting: 1.5.1 Normal fine particles of specific wear metals; 1.5.2 Non-suspendable particles of specific wear metals and of contamination elements; 1.5.3 Less populated large particles (10 µm to 50 µm) of specific wear metals; 1.5.4 Contamination elements; and 1.5.5 Additive elements. 1.6 This test method uses oil-soluble elements 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 (referenced by Test Methods D5185 and D6595). 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
