DUS 2045:2018 Standard test method for determination of additive elements in lubricating oils by inductively coupled plasma atomic emission spectrometry, First Edition. (15 page(s), in English)

This Draft Uganda Standard covers the test method for the quantitative determination of barium, boron, calcium, copper, magnesium, molybdenum, phosphorus, sulfur, and zinc in unused lubricating oils and additive packages. 

The precision statements are valid for dilutions in which the mass % sample in solvent is held constant in the range of 1 to 5 mass % oil. The precision tables define the concentration ranges covered in the interlaboratory study. However, both lower and higher concentrations can be determined by this test method. The low concentration limits are dependent on the sensitivity of the ICP instrument and the dilution factor. The high concentration limits are determined by the product of the maximum concentration defined by the linear calibration curve and the sample dilution factor.  Sulfur can be determined if the instrument can operate at a wavelength of 180 nm. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
