FAT and SAT tests are two types of acceptance tests performed at the end of the manufacturing process of a given product, which verify whether or not the equipment or system in question is functioning properly and complies with all relevant specifications.
Performing FAT and SAT tests can offer businesses a number of significant competitive advantages. Among the most notable benefits are, for example, being able to prevent any potential problems arising; peace of mind that products have been subjected to various examinations; as well as the security of having all the information related to a given system available before it’s brought into use.
Definitions of FAT and SAT tests along with the specific features of each one are outlined below.
Differences between FAT and SAT tests
FAT tests
First of all, we need to define what exactly are FAT tests. Factory Acceptance Tests are designed to inspect a product or solution on the supplier’s site before being sent to the customer, based on previously defined parameters related to functionality, performance and quality.
This type of test thoroughly reviews the tool and therefore guarantees the solution meets documentary, dimensional and process-design specifications.
In addition, it’s worth noting that FAT tests are carried out alongside customers, in order to share – first hand – all possible learnings about how the system or product works.
SAT tests
As for SAT tests, these are acceptance tests carried out in the field known as Site Acceptance Tests, hence the letters SAT, meaning the examinations that are carried out at the final location, this time on the customer’s premises. This means they are the first operational tests of a given solution.
This type of test is intended to ensure the correct operation of the product or system at its first start-up and to verify it meets all the requirements of both functionality and performance. SAT tests also include all the necessary training of the technical staff responsible for managing and handling this type of solution.
As mentioned, both FAT and SAT tests are carried out alongside customers to be able to convey all expertise and understanding of the machinery involved.
Performing FAT and SAT tests before any tools designed for lifting and handling large loads are brought into service is essential, especially for industrial companies. These types of tests prevent any issues whilst offering greater security alongside optimal and efficient resolution of work processes.
