Standard Test Method for Determination of Additive Elements in Lubricating Oils by EDXRF Analysis

active, Most Current
Publication Date: 15 December 2016
Status: active
Page Count: 7
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method covers the quantitative determination of additive elements in unused lubricating oils and additive packages, as shown in Table 1.

Additive packages require dilution with a contamination free diluent (base oil) prior to analysis. The dilution factor has to be calculated from the expected concentrations to bring the concentrations for all elements into the ranges listed in Table 1.

Some lubrication oils will contain higher concentrations than the maximum concentrations listed in Table 1. These samples require dilution with a contamination free diluent (base oil) prior to analysis. The dilution factor has to be calculated from the expected concentrations to bring the concentrations for all elements into the ranges listed in Table 1.

This test method is limited to the use of energy dispersive X-ray fluorescence (EDXRF) spectrometers employing an X-ray tube for excitation in conjunction with the ability to separate the signals of adjacent elements by using a high resolution semiconductor detector.

This test method uses inter-element correction factors calculated from a fundamental parameters (FP) approach or from another matrix correction method.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

The preferred concentration units are mg/kg or mass %.

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.

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.
