Functional safety
Functional safety is continuous improvement
Systems that are critical to safety must meet even the strictest standards and regulatory requirements in a cost-effective and controlled manner. Our functional safety solutions ensure that products and systems operate reliably in all conditions and successfully pass the required assessments and certifications.
Functional safety as a part of product development
Our functional safety experts support the entire product lifecycle from defining the safety concept to verification, validation and independent assessments. Our solutions ensure that safety-critical systems meet the strictest standards as well as the specific requirements set by industry sectors and regulatory authorities.
With our experts’ extensive experience across various industries, including machinery and equipment manufacturing, the rail and automotive industries, and nuclear and medical technology, we can apply standards (IEC 61508, EN ISO 13849, ISO 26262) and safety principles in a profound yet practical manner.
Combining functional and digital safety offers a comprehensive approach to effectively and proactively protect modern, digitalised cyber-physical systems.
Functional safety protects people, ensures reliable operation, and builds trust in the product throughout its entire lifecycle.
Our functional safety services
Safety management
Functional safety ensures that products meet requirements and remain safe throughout their entire lifecycle. Our certified experts (TÜV SÜD Functional Safety Professionals) support design, documentation, and the definition of necessary procedures.
Our expertise covers, among other things, risk analyses, failure mode and effects analyses (FMEA), fault tree and reliability analyses, as well as safety integrity level (SIL) verifications.
System assesments
We manage risks and enhance product quality, lifespan, and value through functional safety assessments.
Assessments and gap analyses are carried out across several industries, such as general industry (e.g. IEC 61508), nuclear power (YVL, IEC 61513), medical technology (e.g. ISO 14971, IEC 62304), automotive (ISO 26262), and machinery and equipment engineering (e.g. ISO 13849, ISO 25119).
Safety development and V&V
Our long experience in developing critical systems brings confidence to safety management, analytics, and project verification and validation (V&V).
Our expertise includes embedded system software development and certification, as well as comprehensive services for safety-critical sectors such as machinery, rail, aviation, automotive, medical, and nuclear industries.
Independent safety assessment services (ISA)
We are a FINAS-accredited Type C inspection body, accreditation number I051. We perform standard-compliant safety assessments for control, command and signalling subsystems (CCS) as well as for rolling stock subsystems (RST).
Assessments are carried out in accordance with standards EN 50126, EN 50128, EN 50129, EN 50159, IEC 61508 and EN 50716. Our operations are guided by standard SFS-EN ISO/IEC 17020:2012, which defines the requirements for inspection bodies.
Cyber-physical security
Our cyber-physical security services help develop and assess safety-critical systems. By combining functional safety and cybersecurity, risks and cyber threats to systems can be identified and managed simultaneously. We assess the functions and documentation related to different stages of the safety lifecycle, ensuring they meet various requirements and standards.
Our special expertise lies in comprehensive risk assessment of safety hazards and threats, in-depth knowledge of multidisciplinary safety and information security standards, and a deep technical understanding of safety-critical systems in industry.
