I also have doubts about 7.5.2. clause. It talks about validation when verification is not possible. Does anyone have examples of processes you validated?
I found an example for this clause, not in food industry but in asphalt industry where my friends work for.
They made asphalt with packaging using a 200 L drum.
In their experience, it's difficult to weigh the drum since the product is very hot (approx 150 degrees celcius) after filling and also the weigh of the drum can be vary.
So they choose to use a stick with dedicated sign for the height of the product in the drum (200 L ~ 78,5 cm for filling temperature).
The stick is also checked regularly with a calibrated equipment to ensure the sign is correct
This process is included in clause 7.5.2
I hope this helps.
