IEC 62381:2006 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. It cancels and replaces IEC/PAS 62381 published in 2004. This first edition constitutes a technical revision. This bilingual version (2013-04) corresponds to the monolingual English version, published in 2006-11.
