ASTM D5185-02

Standard Test Method for Determination of Additive Elements, Wear Metals, and Contaminants in Used Lubricating Oils and Determination of Selected Elements in Base Oils by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES)

SCOPE
1.1 This test method covers the determination of additive elements, wear metals, and contaminants in used lubricating oils by inductively coupled plasma atomic emission spectrometry (ICP-AES). The specific elements are listed in Table 1.
1.2 This test method covers the determination of selected elements, listed in Table 1, in re-refined and virgin base oils.
1.3 For analysis of any element using wavelengths below 190 nm, a vacuum or inert-gas optical path is required. The determination of sodium and potassium is not possible on some instruments having a limited spectral range.
1.4 This test method uses oil-soluble metals for calibration and does not purport to quantitatively determine insoluble particulates. Analytical results are particle size dependent, and low results are obtained for particles larger than a few micrometers.
1.5 Elements present at concentrations above the upper limit of the calibration curves can be determined with additional, appropriate dilutions and with no degradation of precision.
1.6 For elements other than calcium, sulfur, and zinc, the low limits listed in Table 2 and Table 3 were estimated to be ten times the repeatability standard deviation. For calcium, sulfur, and zinc, the low limits represent the lowest concentrations tested in the interlaboratory study.
1.7 The values stated in SI (metric) units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 6.1, 8.2, and 8.4

INTRODUCTION
Costs associated with maintenance due to engine and machine wear can be significant. Therefore,
diagnostic methods for determining the condition of engines and other machinery can be important.
This test method is intended to quantify, for the purpose of equipment monitoring, the concentration
of metals in used lubricating oils. Although the precision statement was determined by analyzing a
variety of used oils this test method can, in principle, be used for the analysis of unused oils to provide
more complete elemental composition data than Test Methods D 4628, D 4927 or D 4951.
