Abstract : This thesis examines spectrometric oil analysis data from the A/E35U-3 and the Portable Wear Metal Analyzer (PWMA). Data from the two instruments is compared using simple linear regression analysis to obtain equations that can be used to convert the A/E35U-3 values to PWMA values. The current JOAP Laboratory Manual is based on A/E35U-3 measurement values and is used as an aid in determining the condition of lubricated engine components. The lack of a counterpart manual for the newly introduced PWMA makes it mandatory that values based on the A/E35U-3 have a conversion to values based on the PWMA. Through transformation equations to be developed in this paper, it will be possible for the PWMA user to utilize the current laboratory manual until based on PWMA values is released. Keywords: Oil analysis program, Spectrometry.
