Examination

(those who have finished may leave earlier.)

Requirements

This training is designed to provide benefit for engineers with some experience in Functional Safety. It is highly recommended that participants either have experience in Safety of Machinery applications or have attended an introduction course on Functional Safety.

Exam

Prerequisite to do the examination is that the applicant has to attend Yokogawa's training course “TÜV Rheinland Functional Safety Engineer SIS”.

  • Pass score is 75%.
  • There are 60 multiple (3) choice questions. At the most 2 good answers per question are possible, which is indicated if applicable.
  • There are 7 safety cases. The maximum points to be earned per case are mentioned.
  • The examination questions and exercises will be handed over at the start of the examination.
  • It is not allowed to bring any documents or (hand held) pc to the exam.
  • It is not allowed to take any documents or notices from the exam.
  • Check of the examination results will be done by two functional safety experts of Yokogawa.
  • Counter check will be done by TÜV Rheinland.
  • Discussion about the results is not possible.
  • Applicants who succeed will receive their certificate from TÜV Rheinland, which may take some weeks.

Re-examination (for those who did not pass the examination)
