FS ENG SIS · 2nd extension · exam only

Certificate extension

After 10 years, the FS Engineer (TÜV Rheinland) SIS certificate can be extended for a second time, for a further 10 years. To apply for this extension, you must complete the eligibility form for the second extension, retake and pass the FS Engineer (TÜV Rheinland) SIS examination.

Who can book it

  • You extended your FS Engineer SIS certificate after 5 years and your certificate is still valid, or it expired less than 6 months after the 10 years.
  • You re-sit the exam and must pass it. This reflects the updates of IEC 61508 and IEC 61511 and the competence refreshing required by IEC 61508, clause 6.2.13.
  • Exam only: the course is not included.
