Complete F.A.T. Runoff

Having new equipment and machine systems customized to your business can give you a huge advantage over your competition, but if it isn't working up to your company's standards, it can also be the source of some huge headaches.

At A&H Custom Machine, we strive to be the solution to your headaches and not the cause – which is why we provide a complete Factory Acceptance Test (FAT) Runoff. In other words, we perform extensive testing on the machines and systems that we provide for our clients. This is done in our custom machine facilities to deal with any problems before the systems are installed at your place of business.

What is involved in the FAT Runoff Process?

The purpose of the FAT is essentially to discover and fix any bugs in machines or systems before the installation process. Testing the system first allows the client to be up and running shortly after installation without worrying about factory quality issues that may arise.

While several routine tests may be conducted, the specifics of the FAT will depend on the client and the product itself. Generally speaking, a FAT will involve a comprehensive inspection, a contract audit and a water test.

  • Comprehensive inspection – typically, this will be determined by the specific equipment and any special requests that the customer has made. For example, as part of the inspection, there may be a checklist to ensure that the actual parts of the products match the design drawings.
  • Contract audit – the original contract between the manufacturer and the customer is reviewed to ensure that all obligations have been met.
  • Water test – The final product is then tested to simulate how it will be used once it is in operation. The purpose of the water test is to verify that the final product is fully functional. Verification of documents such as user manuals are typically included in this part of the process.

FATs are essential to ensure that any system being delivered and installed at your place of business is fully operational, but they also help protect your employees' safety.


The main difference between a FAT and SAT is that the Factory Acceptance Test (FAT) takes place at our facility, and SAT stands for Site Acceptance Test and takes place at the client's site after the equipment has been shipped and installed.

Why we perform FAT Runoffs at A&H Custom

A&H Custom Machine performs Factory Acceptance Tests (FAT) of all custom machines, equipment and control panels to verify the functional performance of all systems prior to shipment. Conducting FATs in-house with the client present is the best way to determine that everything is in working order and meets your needs before the equipment is shipped off to the client and installed.

FAT allows us to give the client a firsthand look at the new equipment and some in-house training. If there is an area where we have missed the mark, then the FAT gives us instant feedback and allows us to correct the problem before the product is shipped to the client. FATs are conducted at no extra cost to the client and are part of our commitment to quality.
