Factory Acceptance Testing (FAT)

A process that evalutes equipment and/or the logic solver and associated software together during and after the assembly process to ensure it satisfies the requirements of the design specifications and safety requirement specification (SRS). FAT is typically conducted to assess for any deviations or abnormalities during testing.

The ISA/IEC 61511 standard (Clause 13) requires that the need for a FAT should be identified during safety planning for a project, and also provides guidance on how a FAT should be planned and conducted. aeSolutions SIS engineers have the experience to develop these plans, oversee their execution as an independent 3rd party, or execute these tests. aeSolutions operates its own FAT lab -- a 10,000 square foot FM approved and UL 508a certified panel fabrication and testing facility -- to ensure any potential panel issues are resolved prior to shipping the system.
