Standard Test Method for Determination of Calcium, Chlorine, Copper, Magnesium, Phosphorus, Sulfur, and Zinc in Unused Lubricating Oils and Additives by Wavelength Dispersive X-ray Fluorescence Spectrometry (Mathematical Correction Procedure)

Importancia y uso:

5.1 Lubricating oils can be formulated with additives, which can act as detergents, anti-oxidants, anti-wear agents, and so forth. Some additives can contain one or more of calcium, copper, magnesium, phosphorus, sulfur, and zinc. This test method can be used to determine if the oils, additives, and additive packages meet specification with respect to content of these elements.

5.2 Several additive elements and their compounds are added to the lubricating oils to give beneficial performance (Table 3).

5.3 This test method can also be used to determine if lubricating oils, additives, and additive packages meet specification with respect to chlorine concentration. In this context, specification can refer to contamination.

5.4 This test method is not intended for use on samples that contain some component that significantly interferes with the analysis of the elements specified in the scope.

5.5 This test method can complement other test methods for lube oils and additives, including Test Methods D4628, D4927, D4951, and D5185.
