2. FAT The Factory Acceptance Test (FAT) is a process that evaluates the equipment during and after the assembly process by verifying that it is built and operating in accordance with design specifications. FAT ensures that the components and controls are working properly according to the functionality of the equipment itself. As the name suggests, this testing is performed at the factory. FAT is typically conducted in order to assess any discrepancies and non-conformities, as well as develop a process for how they are to be handled. Deviations or abnormalities observed during testing are documented in a problem report and corrected prior to shipment. The FAT is a customized testing procedure for different types of systems and the tests are executed before the final installation at the plant. 

3. Why is Factory Acceptance Testing Required? FATs are beneficial not just for the buyer and end users but for the manufacturer as well.  Both parties can be assured that the equipment meets all the contractual specifications and any issues can be addressed before arriving at the customer’s site.  Rectifying issues while the system is still in the possession of the manufacturer helps to keep the project on track and within budget.    FATs almost always save time and money over fixing issues in the field. Our broad factory acceptance test is the most lucrative way to ensure that your equipment or plant operates correctly. As a highly qualified, independent third-party, we have the trusted skills and resources to perform steadfast testing. Alternatively, we can witness appropriate testing on your behalf. In many cases it is difficult to predict the correct operation of the safety instrumented system or consequences due to failures in some parts of the safety instrumented system. For that reason the FAT is a valuable check of the safety issues. The safety of your employees is always a top concern so the quality assurance gives you the peace of mind that all components of your system are functioning the way they should, and within the full range of operating specifications.

4. Objective of FAT Achieve independent proof of functionality, quality and integrity with our comprehensive checking process Verify all important documents, such as manuals, instructions, plans, drawings, piping and instrumentation diagrams (P&IDs) Ensure that your equipment or plant performs as expected under the testable range of likely conditions, including mishandling and error

5. Process of FAT The main objective of the FAT is to test the safety instrumented system (logic solver and associated software together). The tests are normally executed during the final part of the design and engineering phase before the final installation at the plant. The FAT is a customized procedure of checking the safety instrumented system and the safety instrumented functions according to the safety requirements specification. The FAT includes appropriate general testing procedures for verification of the correct operation of the safety instrumented system. Since the testing activities are general methods the FAT is applicable to programmable or non-programmable safety instrumented systems. The most important part of the FAT addresses specification of the test cases i.e. clear description of the test cases, well-structured test procedures and relevant test cases.

6. It’s important to note here that there are varying levels of an FAT.  They can be performed at a very basic level, such as setting up the main pieces of the system with temporary wiring and making sure everything moves as it is supposed to, or a more complete FAT can be conducted where the manufacturer physically builds the whole system in their shop to test it fully.  In the latter example, the system is then taken apart, moved to the customer’s site, and put back together again. The FAT is normally performed at the manufacturer work shop. The manufacturer checks that the safety instrumented system works as intended and according to the requirements stated in the safety system works as intended and according to the requirements the safety requirements specification

7. During the FAT the manufacturer checks: The used equipment are mending to the specification eg , compatible HW and SW versions The used equipment are installed according to manufacturer’s specification The input and the outputs are connected according to the drawings The calibration of the equipment are correct The trip points operate according to the requirements in the SRS. The associated software operate according to the requirements in the SRS the outputs and their actions behave according to the SRS The reset functions operate according to the SRS The alarms operate according to the SRS The operator functions operate according to the SRS The bypass functions operate according to the SRS The manual shutdown functions operate according to the SRS The diagnostic alarm functions operate according to the SRS
