Functional Safety Assessments should be completed by an independent body and must be in the form or either a person, department or organisation. The level of independence is determined either by the severity of the consequence the safety function is trying to protect against, or the Safety Integrity Level (SIL) of the safety function.
Functional Safety Assessments can provide significant advantages in the early identification of compliance gaps and opportunities for streamlining processes, making it easier to demonstrate compliance with IEC61511
