Analyzing Sample History and Setting Goals

As part of a pro-active program of contamination control, it is important to set cleanliness goals. These will help give the program direction and the ability to measure success by direct comparison with stated goals.

When starting out, there may be a large difference between current contamination levels and the desired end point. It is important to get to the end point in achievable steps. There may be many things that need to be addressed in achieving target contamination levels - cleanliness at lube fill points, in service cleanliness through better filtration, in service cleanliness through offline filtration (filter carts). Generally these things cannot be implemented all at once and each of them will have an incremental cleanliness benefit. So, setting targets to coincide with expected results at implementation of each improvement makes sense.

The performance of a filter defines the ratio of particles downstream (after the filter) to the particles upstream (before the filter). So, the result depends on the number of particles upstream - i.e. how contaminated the system is to start with. This means that if you use exactly the same filter in a dirty system and a clean system, the dirty system will be dirtier after the filter has run for the same amount of time as the clean system...hardly surprising! The cleanliness of a system after running a filter for a certain time depends on the initial cleanliness.

It makes sense then to set your cleanliness goals in achievable steps from the start point to the end point. So the start point must be known.

A convenient way to do this in FleetOil is to use the Alarm Group Report:

- From the Main Menu, click Alarms | Alarms Maintenance

- Select the alarm group in question and click on the button "Print Alarm Group Statistics Report" (2nd from right on the button bar)

The report generated will list all equipment in the alarm group. It will also list the predictors (tests) for the lab(s) you use, together with the historical statistical values for each predictor using results from all equipment in the alarm group:

- minimum

- maximum

- average

- standard deviation

- count

These figures can be used to easily generate starting points for setting cleanliness goals.
