1.1 General applicability
This International Standard defines requirements and checklists for the factory acceptance test (FAT), the factory integration test (FIT), the site acceptance test (SAT), and the site integration test (SIT). These tests are carried out to demonstrate that the automation system meets the requirements of the applicable specification.
This document provides a means for all parties, including the owner, the buyer, and the vendor, to clearly establish and agree on the scope of activities and responsibilities involved in performing these tests in order to achieve a timely delivery and acceptance of the automation system. The activities specified in this document can be used to develop test plans adapted to the specific requirements of the process/plant/equipment.
The annexes of this document contain checklists which are available for consideration when preparing specific test procedures and documentation for a specific automation system.
1.2 Exclusions
1.2.1 Prior- and post-test activities
Engineering and manufacturing activities prior to or after the FAT, FIT, SAT and SIT, such as loop checks and commissioning, are not covered by this document.
1.2.2 Regulated industries
For applications in the pharmaceutical or other highly specialized industries, additional guidelines (for example, good automated manufacturing practice (GAMP)), definitions and stipulations apply in accordance with other applicable existing standards.
1.2.3 Safety instrumented systems
The user can utilize this document to develop necessary testing for basic checks of a safety system, however, this document does not cover validation of a safety system. IEC 61511 provides requirements for checks and validation of safety instrumented systems.
1.2.4 Manufacturing execution systems
Testing and verification of manufacturing execution systems (MES) is not covered by this document.
1.2.5 Advanced process control
Testing and verification of advanced process control (APC) is not covered by this document.
1.2.6 Security for industrial automation and control systems
Although this document includes a limited number of network checks, it does not cover complete network and system security. IEC 62443 provides requirements for automation and control systems cyber security.
