You connect it to the circuit breaker only for testing and once you are done and want to ship the cabinet, you simply disconnect the wires from the topside of the circuit breaker. Now that you have a good idea about the concept and feel comfortable with it, let’s explore FAT a bit further through a practical example. This is actually an acceptance test, done by you, on your computer before the document is sent. Verify that each individual assembly interfaces and operates properly with other components and assemblies of the system. All instrumentation used for test validation must be calibrated prior to and following test activities.

Obviously, there is scope to be flexible, but the ultimate aim as noted is to be efficient and ensure that the project understands the correct information to be included. Testing duration will depend upon what type of plant and equipment is being reviewed. Not all Plant and Equipment on a project will need to be factory tested. It will depend on the requirements set out in the Owners Project Requirements [OPR] and Commissioning Plan/Specification. By systematically carrying out all items on the checklist, all FAT participants from both sides can gain the assurance needed feel prepared and ready for start-up.

The Purpose of Factory Acceptance Test

The below details a format that can be used and specified in the commissioning plan/specification to ensure the whole project provides the required format. During a factory test for HVAC equipment especially, the testing is usually completed under stringent conditions within a chamber that is equipped with instrumentation to allow remote monitoring and reporting of data. DATAMYTE also lets you conduct layered process audits, a high-frequency evaluation of critical process steps, focusing on areas with the highest failure risk or non-compliance. Conducting LPA with DATAMYTE lets you effectively identify and correct potential defects before they become major quality issues.

Performing a brief, shallow FAT will inevitably show up as a problem in the third shift, nine months down the road. Communication challenges can significantly hinder the efficiency and success of the FAT process. Miscommunications between the manufacturer and the purchasing company may lead to misunderstandings about the test procedures, the equipment’s specifications, or the acceptance criteria.

Performing FATs involves risk and hazards due to dealing with high-pressure fluid that could cause mechanical failure of the valves and actuators. Therefore strict safety consideration and implementation based on company risk procedures and regulations are essential. Extreme caution should be applied during the testing of both valves and actuators to prevent injury. Wearing safety glasses, a safety hat, and safety shoes in some areas of the factory are essential practices. It should be noted that the high-pressure gas test requires an especially high level of safety; the valve should be tested in a pit at a sufficient distance from personnel, and the pit should be equipped with gas detector alarms.

Never trade away adequate factory testing to meet a shipping deadline. You will ultimately pay the price for this in longer start-ups and lost productivity at the factory. In the FAT, use the materials that will be put in operation during actual production. A Factory Acceptance Test (FAT) is required to ensure that the customer’s requirements are met before a plant or machine is delivered. During the FAT, faults and problems can be identified and rectified before handover to the customer takes place. In short, it’s more time and cost effective to do an FAT and do it right to mitigate any issues prior to delivery.

That being said, savvy customers will continue to demand FATs and training in a supplier’s facility before the machine ships. Some suppliers are expanding their facilities to include more FAT handling, in a private, secure environment, where strict confidentiality of all technologies is assured. FAT provides the opportunity to ensure that the manufactured equipment adheres to the highest quality and compliance standards. It encompasses a detailed review of the equipment’s design, materials, and functionality to ascertain compliance with industry regulations and standards.

DATAMYTE is a quality management platform with low-code capabilities. Our Digital Clipboard, in particular, is a low-code workflow automation software that features a workflow, checklist, and smart form builder. This tool lets you create a comprehensive checklist for your FAT, with detailed procedures and acceptance criteria.

These platforms also foster enhanced collaboration and communication by providing a central hub for all FAT-related activities. This feature ensures that everyone involved in the process, from the equipment manufacturers to the purchasing company representatives, has instant access to the same accurate, real-time information. This transparency reduces miscommunications and aligns expectations. Factory Acceptance Testing (FAT) provides essential benefits that justify the time, effort, and resources invested into executing it. Employing a robust FAT process can deliver substantial advantages, ranging from quality assurance to cost savings.

Wouldn’t it be nice to get some reassurance prior to receiving your equipment? Conducted at the manufacturer’s site prior to delivery and installation, these tests help to identify any issues and correct them prior to shipment. Basically, an FAT is a “factory debug” to assure that when the system arrives on site, it should be able to be installed and get up and running quickly and smoothly. If you’ve been wondering what exactly an FAT entails and why should get one, we’ve got some answers for you in this post.

For example, let’s say that our analog input card will receive 4-20 mA input signals from transmitters installed in the field. So if the device that will be connected to the PLC digital input is passive, meaning there is no external power required for the device, you can simulate that using only a piece of wire. If the device is active, you can make use of a simulator to simulate the input signal. Consequently, you will have to spend countless hours at the client’s site solving issues that you could have easily taken care of before shipping the control panel. SAT operations typically involve running the equipment for one to two weeks to see if it performs as expected and if any major problems occur.

  • It also ensures quality, controls costs, and maintains the schedule.
  • By prioritizing FAT in your operations, you are safeguarding your investment and effectively mitigating risks of downtime, non-compliance, and substandard product quality.
  • Once the factory acceptance test is included in the project scope, there is no extra cost for the test.
  • Corrective steps will be taken if a test fails and any retesting will be performed if required.
  • But before you ship it you want to make sure that everything works properly.

Following the completion of the tests, all results must be meticulously documented and reported. This documentation includes detailed test reports and results, non-conformance reports (if any issues were identified), and other pertinent observations made during testing. Once the planning phase is completed, the next step is to set up the test equipment and environment. This includes preparing the equipment to be tested, setting up any necessary auxiliary equipment or tools, and ensuring that the testing environment mimics the conditions under which the equipment will ultimately operate.

Getting through the FAT is another milestone in the project, as the software has been proven in design. The next step is to place the equipment in the field and verify everything again using the real world inputs and outputs. The planning presents a set op of the appropriate tests to be carried out and who is responsible for developing the test cases. Appropriate levels of competence and independence of assessors are required. The realization of tests shall be described as well as the personnel responsible to carry out the test.

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.

A list of remaining follow-up items to note any modifications/adjustments or additional tests that need to be made prior to delivery. Also confirm motor classification meets specified class and division standards. Times can vary depending on the complexity of the system and the corresponding FAT, but they are typically scheduled 2-4 weeks prior to the ship date to help maintain on-time delivery. The duration of the FAT can be anywhere from one day up to a couple of weeks.
