Abstract : The Joint Oil Analysis Program previously revised the specification for their spectrometric oil standards in order to incorporate an ICP-AES test method and to transition to commercially manufactured spectrometric oil standards. Historically, a Rotrode-AES test method was the only elemental test method used to verify the quality of the spectrometric oil standards. The Rotrode-AES test method was a labor and time intensive process that did not exhibit a high level of accuracy and repeatability. The JOAP wanted to incorporate an ICP-AES test method in order to obtain a more accurate determination of the true concentration of the elements in the spectrometric oil standards and to reduce the cost and time needed to conduct quality assurance. Both the Rotrode-AES and ICP-AES test methods are now part of the qualification inspection in order to ensure that commercially manufactured spectrometric oil standards are identical to those that have been produced in-house by the JOAP. This report covers the qualification testing of Type D19-0, Type D12-XXX series, and Type D3-100, candidate spectrometric oil standards submitted by SCP Science (Conostan) against the requirements of MIL-DTL-85694. In general, the candidate spectrometric oil standards met the requirements of the specification. A few specific data points were analyzed and waived based on alternative testing and analysis. As a result of this testing and analysis effort the SCP Science (Conostan) Type D19-0, Type D12-XXX series, and Type D3-100 spectrometric oil standards have been qualified to the specification. Since this qualification testing effort was only the second time the full range of data required by MIL-DTL-85694 has been collected, analysis of the data has led to the conclusion that several of the requirements of the specification need revision. Several changes to the specification are therefore under consideration based on historical knowledge of JOAP manufactured spectrometric oil standards and the MIL
