Scope

1.1 This automatic wear particle analysis2 test method for in-service lubricants describes using a combination of pore blockage particle counting and energy dispersive X-ray fluorescence (EDXRF) spectrometry for the quantitative determination of solid particle counts larger than four (4) micrometres, and elemental content of suspended particulate of iron (Fe) and copper (Cu) in such lubricants. 1.2 This test method provides for the determination of the elemental content of suspended particulate of Fe greater than 4 µm in the range of 6 mg/kg to 223 mg/kg. Suspended particulate of copper greater than 4 µm is determined in the range of 3.5 mg/kg to 92.4 mg/kg in the lubricant. Total particle count greater than 4 µm is determined in the range of 11 495 particles ⁄mL greater than 4 µm to 2 169 500 particles ⁄mL greater than 4 µm in the lubricant. 1.3 This test method is applicable to all known in-service lubricants (API Groups I-V) at any stage of degradation. 1.4 This test method uses an empirical inter-element correction methodology. 1.5 The values stated in SI units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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.
