Why Factory Acceptance Test?

The final acceptance test after the assembly of components

Why Factory Acceptance Testing (FAT)?

The Factory Acceptance Test (also called Final Acceptance Test or Factory Acceptance Test) is used to verify that the manufactured assembly or finished device fulfills its intended purpose.

The Factory Acceptance Test (FAT) is used by CrossTEQ's quality personnel to verify that the manufactured assemblies or devices meet their intended purpose. The FAT validates the operation of the equipment and ensures that the customer's order specifications and all other requirements have been met.

Test requirements and test instructions for final acceptance test for assemblies and devices

Qualification

CrossTEQ ensures that personnel are properly trained in performing Factory Acceptance Tests. Only regularly trained production personnel are allowed to perform FAT (and functional tests as well as burn-in tests).

Test environment & precautions

Our quality personnel (production manager and production engineering manager) maintain and implement work instructions, test environment guidelines, and any precautions for functional testing (especially for electrostatic sensitive devices!).

Testing Software

The test application software guides the tester through the various test steps and executes the automated test section where possible. The test application documents and creates digital test reports, which the tester must sign.

Reports

Deviations/defects are to be noted on the test report. Any corrective actions and the subsequent regression tests shall be described in detail at the request of the test application software.

Per the Supply Agreement, CrossTEQ archives reports as part of the Device History Record (DHR). Each report must be traceable to the component by part identification number and serial number. 

Responsibility

Only after testing is successful, assembly of the assembly or device is completed. Our quality personnel perform the Quality Assurance (QA) buyoff for product release and confirm proper manufacturing, testing and reporting by electronic signature before delivery to the customer.

Application example for Factory Acceptance Test

FAT of a radiotherapy imager in medical technology

This FAT is an X-ray test developed in cooperation with the customer for the acquisition of X-ray test images with radiotherapy imagers. 

In this process, both automatic and manual visual test steps are performed in a specifically manufactured X-ray chamber to determine the image quality of the imager. The aim is to find errors caused by the interaction of the components.
