    (What is a Work Item?)

    WK60565

    1. Scope

    1.1 This test method covers the determination of wear metals and contaminants in used industrial oils and grease samples by sweeping flat electrode atomic emission spectroscopy (SFE-AES). 1.2 Industrial oil includes lubricant oil, gear box oil, hydraulic fluid, compressor oil, turbine oil, and so on and can be mineral or synthetic. 1.3 This test method provides a quick indication for abnormal wear and the presence of contamination in new or used industrial oils and greases by immediately reporting: (1) normal fine particles of specific wear metals; (2) less populated large particles of specific wear metals; (3) non-suspendable particles of specific wear metals and of contamination elements; (4) contamination elements; and (5) additive elements. 1.4 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. 1.5 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.6 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.

    Rationale

    SFE-AES instruments are found in used oil and grease analysis and are not currently covered by any standard practice, guide, or test method. The proposed test method will describe a means of approach to provide consistency in measurements and reporting between laboratories.

    The title and scope are in draft form and are under development within this ASTM Committee.
