ASTM D4951 Standard Test Method for Determination of Additives in Lubricating Oils

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D4951 standard. This test method covers the quantitative determination of barium, boron, calcium, copper, magnesium, molybdenum, phosphorus, sulfur and zinc in unused lubricating oils and additive packages.

Expressions of precision apply to dilutions where the % mass sample in solvent is kept constant within the range of 1% to 5% by mass of oil.

The precision tables describe the concentration ranges covered in the interlaboratory study. However, both lower and higher concentrations can be determined with this test method. Low concentration limits depend on the sensitivity and dilution factor of the ICP device. High concentration limits are determined by multiplying the maximum concentration defined by the linear calibration curve and the sample dilution factor.

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.
