BS EN 62381:2007 Automation systems in the process industry - Factory acceptance test (FAT), site acceptance test (SAT), and site integration test (SIT)
This International Standard defines procedures and specifications for the Factory Acceptance
Test (FAT), the Site Acceptance Test (SAT), and the Site Integration Test (SIT). These tests
are carried out to prove that the automation system is in accordance with the specification.
Engineering and manufacturing activities prior to these tests are not covered by this standard.
The description of activities described in this standard can be taken as a guideline and
adapted to the specific requirements of the process/plant/equipment. A typical sequence of
activities and events is shown in Figure 1, their relationship in Figures 2 and 3.
