What is a Site Acceptance Test (SAT)?

A Site Acceptance Test (SAT) is a process in which a machine or plant is tested and accepted at the customer's site. The purpose of the SAT is to ensure that the machine or system has been properly installed and configured and is ready for operation. Before the Site Acceptance Test can take place, the Factory Acceptance Test (FAT) is first performed at the manufacturer's plant.

Why do you need a Site Acceptance Test?

A Site Acceptance Test (SAT) is required to test a plant or machine supplied by the manufacturer. The SAT enables the customer to check whether the requirements are met and the machine is functional. The SAT is used to accept the plant or machine at the customer's site.

What is the difference between SAT and FAT?

The main difference between a Site Acceptance Test (SAT) and a Factory Acceptance Test (FAT) is the place and time of execution. The Site Acceptance Test is performed directly at the customer's site after a successful Factory Acceptance Test. It is used to ensure that the plant or machine has been properly installed and is operational. The Factory Acceptance Test is performed at the manufacturer's site before the respective plant or machine is delivered to the customer. The purpose of the FAT is to ensure that the customer's requirements are met.
