Functional Safety Service

Functional Safety Certification:

TÜV Rheinland is one of the world leaders in Functional Safety and has more than 25 years experience in evaluating Safety and 75% of the market share of the Functional Safety Certifications worldwide. Where necessary providing clarity and understanding to customers on the requirements of Functional Safety for today’s technological challenges including finding solutions for their end target of:

Software
Electronic measuring and control system and monitoring equipment
Programmable electronic systems
Process automation
Industrial machinery

Our main accreditation includes “quality and safety” especially functional safety such as safety management of software and systems (with or without software) and their components (electronic components, measuring and control devices, programmable electronic systems).

Systems, sub-systems, modules to Components:

TÜV Rheinland Functional safety group covers a wide range of equipment covering from large complex systems, sub-systems, modules and components. For example where a Programmable Electronic Systems (PES) is required for control process and also maintain Safety. For safety assessment detailed failure analysis are performed to detect the total effects. Part of this analysis includes risk analysis and calculation of other safety parameters such as Safety Integrity Level (SIL), Probability of Failures per Hour (PFH), Probability of Failures on Demand (PFD), Safe Failure Fraction (SFF), Performance level (PL) and others.

Certification and Marking:

Automation, Software and Information Technology (ASI) carries out type approvals of electrical/electronic products. A positively completed test results in the certification of the product and the optional issue of a test mark. There are two test marks:

1. Type approved

The type approval provides the proof that the tested product meets the requirements of the relevant product standards and can be used in the specified range of operation. The type approval is a basis for the producer's CE declaration of conformity, as all regulations are applied as base of testing, which are necessary for the proof of conformity according to the relevant European directives at least low voltage- and EMC-directives.

This assessment entails:

Calculations of probability of failures (PFH/PFD)
Failure mode and effect analysis (FMEA)
Software assessment
Environmental tests incl. EMC
User documentation, safety manual etc

2. Functional Safety FS - type approved

The test mark "Functional Safety FS" is applied to products which - according to the product standards - require functional safety (failsafe behavior) and which are used in safety related applications. The safety design of the products according to the relevant standards, including the EN 954 and/or the IEC 61508, has to be proved. Together with the product's implemented measures to ensure the failsafe behavior, the complete documentation concerning the overall life-cycle of the product as well as the implemented Functional Safety Management, which is being applied to all life-cycles of the product acc. to the standard's requirements, has to be surveilled and assessed. A certificate and test mark "Functional Safety FS" includes concerning it's meaning the mark "Type approved".
