I had a similar experience, but with the purchase of a 2 identical pieces of equipment, but they were being placed at two different locations. We had to validate each piece of equipment, but with regards to our Test method validation, we only had to do that on equipment due to the fact that they were identical. But with respect to this particular situation, I believe that it depends on the equipment durability and equipment use. For instances, I know certain pieces of equipment can be placed at different locations and don’t need to be re-validated they just need to be re-calibrated and a memo for justification from quality could be suffice, if this equipment is used to develop or test an upper level class of device, then I do believe that a revalidation is to be implemented. Ideally, you want to ensure that the equipment is producing the same results like in its previous location.
