FAT or Factory Acceptance Testing is executed at the vendors test facility.The FAT is an inspection that includes both static and dynamic exhaustive testing of systems or major system components to support the qualification of equipment or a system. The tests must verify that all functionality detailed in the Material Requisition (MR) is embodied and performs as specified. It is written by the manufacturers and executed by the client or client representative.
SAT or Site Acceptance Testing is executed at the clients site. The SAT is related to the FAT and also involves inspection and dynamic testing of systems or major system components to support the qualification of equipment. This is written by the client and verifies that the installed functionality of the equipment meets the operational requirements as specified in the MR. The SAT is executed on completion of all commissioning tasks, but prior to the start of Test Run.
FAT and SAT tests are supplied by fb.m. to help customers to reduce the risk that non-compliance or deviations from Requisitions come out through the supply chain. These scenarios might cause a breakdown with consequent risks for safety or environment damages and delays in the project. All this could imply an unprevented increase of project costs.
