PIM Measurment demosntration

Good day.
I have made a couple of PIM tests in my workarea.
Most of them have been successful. Some had issues that were later resolved.
The 64000 question here is:

How do I prove these results? Say, like a datasheet?
I can see that it's passing and I would just put a pass fail response.
But I am being asked to get a result on paper or plots.

It feels like they are asking me to provide a value for the sweetness of a twinkie.

Any help would be greatly appreciated.

Thank you.
