French to English Tech/Engineering Automotive / Cars & Trucks Vehicle parts (packaging tests)

I'm translating instructions for the testing of packaging of vehicle parts- to see how they stand up to handling and transport.

The document has reached me in Spain, so I suppose there is even a small chance that the initials are actually Spanish usage - but I went down that road for a while and didn't make that much progress!

POU occurs in conjunction with POE and POI, so I am doing a triple posting.

First appearance is in a table for these tests, and under the heading of "Typologie pièce" we find "POI - POE - POU". Other headings include the date and place of the tests, the project number, but this is the only piece of information that is filled in.

Further along we have a note saying "sauf spécifications contraires dans le fascicule de préconisation ou CdC pour POI, POU." (we're looking at forklifts here) and "« caractéristiques des moyens de transport utilisés » dans le fascicule de préconisation ou CdC pour POI, POU. " talking about trucks delivering the parts.

All help gratefully received!
