IEC-61508 Functional Safety Red Belt Certification

Course Identifier:  e20-001

IEC 61508 is a basic functional safety standard applicable to all kinds of industry. It defines functional safety as: “part of the overall safety relating to the EUC (Equipment Under Control) and the EUC control system which depends on the correct functioning of the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities.” The fundamental concept is that any safety-related system must work correctly or fail in a predictable (safe) way.

The standard has two fundamental principles: 1. An engineering process called the safety life cycle is defined based on best practices in order to discover and eliminate design errors and omissions. 2. A probabilistic failure approach to account for the safety impact of device failures.

This training guides you through the whole life cycle by explaining the sometimes ambiguous requirements and by providing application examples in order to ensure the correct understanding for all participants.

Our course is structured based on a top-down approach allowing trainees to book one or multiple days tailored to their needs. However, the exam given the fifth day requires that all training days (1-to-4) have been followed by the trainee.
