Dear John M. ,

thx for your kind support .

the problem here is how to apply this methodology

1-should i treat each component individually by applying this analysis on its historical records of wear metals .



2- or should i compare between components with the same serial No. & model in this case
-how can i choose records from each component to compare ( should it be the last lab result of each components ? or what )

also when am trying to monitor the wear metal trends i face challenge on when to consider the trend abnormal is their a specific criteria to determine the abnormal wear trend ?


Thx
