ASTM releases revised ASTM D7751 standard

ASTM International has announced the publication of a revised version of ASTM D7751 – 16, “Standard Test Method for Determination of Additive Elements in Lubricating Oils by EDXRF Analysis.”

The method covers “the quantitative determination of additive elements in unused lubricating oils and additive packages,” and is now complete with a repeatability and reproducibility statement, notes Dirk Wissmann, Senior Product Manager XRF, SPECTRO Analytical Instruments GmbH.

SPECTRO XEPOS energy dispersive X-ray fluorescence (ED-XRF) spectrometers, which feature new developments in excitation and detection that deliver outstanding sensitivity and detection limits and yield remarkable gains in precision and accuracy — are compatible with ASTM D7751 – 16, Wissmann states.

SPECTRO XEPOS spectrometers represent a dramatic advance in ED-XRF technology. They feature breakthrough advances in the multi-elemental analysis of major, minor, and trace element concentrations and are compatible with the new “ASTM D7751 – 16” standard test method — SPECTRO XEPOS spectrometers represent a dramatic advance in ED-XRF technology, comments Wissmann.
