Functional Integrity Certification

Functional Integrity Certification™ is a program that evaluates the most critical attributes of an automation product:

  • Functional Safety
  • Functional Security
  • Availability

The goal of the program is to improve product / system performance by assessing ability to perform in critical situations.

Why is Functional Integrity Certification Needed?

With the evolution of technology and incidents such as Stuxnet, it has become more apparent that security vulnerabilities can impact the operation of a safety instrumented system.

Functional Integrity Certification

There is no safety without security

Integrity certification from exida analyzes how the security design impacts SIS performance

Traditional certification companies have given IEC 61508 SIL 3 approval to products with complicated end user programming and impractical proof testing requirements. This has resulted in failed system designs that are not safe.

Integrity certification from exida evaluates the complexity of implementation and practicality of maintenance procedures.

Availability Evaluation

Availability assessment ensures the dependability of automation products in critical applications. In most continuous process facilities, this means reliable 24x7x365 operation for up to several years at a time.

As part of the evaluation, exida quantifies the false or spurious trip rate of a product using standardized modeling and probabilistic methods. Trip rate data is combined with empirical data to help predict product reliability.

Functional Integrity Certification includes “false trip” failure rates not just safe failure rates.

Functional Integrity Certification

The only product certification program that covers:

  • How the product was designed
  • How the product was tested
  • How the product was manufactured
  • How the product has performed in the field
  • How the product is likely to perform over time
  • How easy or difficult it is to properly apply and maintain the product
