ASTM D4927 Standard Test Method for Elemental Analysis of Lubricants and Additives by Wavelength Dispersive X-Ray Fluorescent Spectroscopy

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D4927 standard. These test methods cover the determination of barium, calcium, phosphorus, sulfur and zinc in unused lubricating oils within the element concentration ranges.

The range can be extended to higher concentrations by dilution of sample samples. Additives can also be determined after dilution. Two different methods are presented in these test methods.

Test Method A (Internal Standard Procedure): Internal standards are used to compensate for the inter-elemental effects of X-ray excitation and fluorescence.

Test Method B (Mathematical Correction Procedure): The measured X-ray fluorescence intensity for a given element is mathematically corrected for potential interference from other elements present in the sample.

Preferred units of concentration are mass percent barium, calcium, phosphorus, sulfur or zinc.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
