Functional Safety is the part of the overall safety of a system or piece of equipment that depends on the system or equipment operating correctly in response to its inputs, including the safe management of likely operator errors, hardware and software failures and environmental changes. It is an additional step beyond the traditional product safety assessment and tackles our ever increasingly complex world of interoperating technologies and the hazards they cause.
IEC 61508, the generic functional safety standard considers the whole lifecycle of electrical, electronic or programmable electronic (E/E/PE) systems and products. Other standards as i.e. EN ISO 13849-1 address also mechanical and pneumatic products.
Specific steps must be carried out by manufacturers to ensure the absence of unacceptable risk due to hazards caused by the mal-functional behaviour of their products and systems.
To design safe hardware and software means that product manufacturers should implement specific techniques such as redundancy, diversity, internal self tests to increase the product robustness against random and systematic failures.
TÜV SÜD provides a broad range of functional safety services for manufacturers in many industries including Automation, Aerospace, Automotive , Rail, Medical, Machinery, Nuclear, Process Automation and Consumer Products. We provide a functional safety assessment of the product including the assessment of the prevention of random failure of the product and its components and systematic failures inadvertently designed into the product. We conduct training programs and workshops to educate product manufacturers on the IEC 61508 series of standards and certify to the full range of international functional safety standards such as ISO 26262, EN 50129, EN ISO 13849-1, IEC 62061 and IEC 60601. Guidance is a key element of our services to support our customers to meet functional safety requirements in their design.
