Functional Safety

Correct functioning of safety-critical systems

The aim of all measures relating to functional safety is to prevent disproportionately high risks caused by malfunctions in electrical and electronic systems that could potentially endanger people, the environment or property.

In a world of increasing automation, more and more control systems and control components are taking over the operation of devices, machines and even entire industrial processes. Similarly, more and more safety functions have to be implemented. As a result, safety-related system developments are becoming increasingly complex. This complexity in turn means that the demands on manufacturers and suppliers are increasing, making the topic of functional safety indispensable in development areas. Nobody wants to bear the liability risks for damage caused, especially to people.

Due to EU Directive 85/374/EEC, which will be replaced by the new EU Directive 2024/2853 at the end of 2026 and thereby toughened, the manufacturer of a product is generally liable for damage caused by the malfunction of its product. Unless this defect was not recognizable according to the state of the art in science and technology at the time the product was brought to market.

Industry-specific standards

The experts at NTC Systems know more than just the theoretical processes of functional safety. We are practitioners – with many years of experience in the development of safety-related electrics and electronics in accordance with the applicable safety standards, laws and guidelines in many industrial sectors. The specifications for the individual processes and the technical implementation of functional safety must be observed in each case. The ISO 26262 standard for road vehicles, for example, is an adaptation of the IEC 61508 nut standard to the specific conditions in the automotive sector.

  • Automotive | ISO 26262
  • Railroad technology | EN50126, EN50128, EN50129
  • Mechanical engineering | DIN 16590, IEC 61508, ISO 62061, DIN/EN 61511, ISO 13849, ISO 25119
  • Medical technology | IEC 60601, IEC 61508, IEC 62304, ISO 13485, ISO 14971
  • Automation/process industry | IEC61508, IEC 61511

Measures from these industry-specific standards must be implemented in order to achieve risk avoidance in line with the state of the art in science and technology.
