We are the partner at your side for your embedded safety projects. We help you to realise your projects correctly and in a legally compliant manner, from planning to implementation. As specialists in our field, we also support and moderate the complex approval and certification processes for your safety solutions in an efficient and targeted manner.
The certification of your security systems is a complex process that you can master with us as your partner. Thanks to our many years of experience, we moderate in a goal-orientated manner between your needs and the requirements of your certifying institution.
Our team works on the basis of the highest levels of the relevant safety and security standards.
IEC 61508 is an international series of standards for the functional safety of safety-related electrical, electronic and programmable electronic systems. Compliance with the standard can significantly reduce the risk to people, the environment or equipment in the event of safety failures in technical systems and machines. It is the “basic standard” for all other (functional) safety standards and deals with software and hardware (electronics). However, the topics of mechanics, hydraulics and pneumatics are not (yet) explicitly covered here.
This standard serves the safety of machines and ensures the functional safety of safety-related electrical, electronic and programmable electronic control systems (e.g. PLC / SPS, sensors, actuators, etc.). It is therefore an industry-specific standard for the automation sector. See also ISO 13849.
The EN ISO 13849 standard is a safety-specific standard that deals with design guidelines for safety-related parts of control systems. It can be applied in parallel with IEC 62061. Both standards are usually used together for a system. While IEC62061 is close to IEC61508 and can be used for software, for example, ISO13849 is more suitable for simple sensors/actuators with possibly very “simple software”.
EN 50128 / 50657 / EN 61508 and EN 50129 are specialisations of the EN 50716 standard and relate to safety-relevant applications for railways, both in the vehicle (“rolling stock”) and for the infrastructure (“signalling”). EN50128 and EN50657 for software are very similar. EN50129 is intended for complete systems as well as for the hardware of railway systems.
The EN 50126 standard includes the so-called RAMS (Reliability, Availability, Maintainability, Safety) methods. This means proof of reliability, availability, maintainability and safety. This standard is used in the system specification of safety systems in the railway sector with the aim of analysing possible hazards and failure probabilities of a system. The standards EN50128 / 50129 / 50657 / EN 50716 supplement this standard.
The IEC 61511 standard is a component of functional safety for the automation and process industry. It defines the necessary procedures for the design of systems that are part of industrial processes using instruments or sensors. It is applicable to process technology systems and includes a special concept for safety circuits.
The ISO 25119 standard describes the safety challenges for tractors and machines in agriculture and forestry. The standard is an industry-specific implementation of IEC 61508 and, like other functional safety standards, defines various levels of criticality.
The ISO 19014 standard deals with the hazards caused by the failure of a safety control system in earth-moving machinery and excludes hazards caused by the equipment itself. These are, for example, hazards from electric shocks, fire and other hazards.
IEC 62443 is an international series of standards for “IT security for networks and systems” and defines the technical and procedural aspects of cybersecurity in an industrial environment, e.g. for machines and systems. It is divided into several sections and defines different roles for industry. These are divided into operators, integrators and manufacturers. Each of these roles is responsible in the standard for a risk-based approach to the prevention and treatment of security risks in their area of activity. Most parts of the standard can be easily transferred to railway technology, and a special adaptation is currently being approved.
Implementing the standard as part of the development of a system (including embedded systems, sensors and actuators) is a matter of course for us and has always been part of every safety development. Safety and security must always be seen together as a “duet”.
The ISO 9001 standard defines the requirements for quality management systems (QMS). In combination with the IRIS railway standard, which was established by the Union des Industries Ferroviaires Européennes (UNIFE), it defines requirements for the QMS of railway manufacturers and their suppliers and engineering service providers.
In order to develop optimal solutions for your projects, we rely on co-operations that have proven themselves many times in the past.
Quantum Rail is our long-standing partner for development projects relating to functional safety applications, such as control and monitoring systems for level crossings, signalling technology as a whole and train control systems. We work with customers to develop requirements, risk and hazard analyses, test and implement software and hardware solutions and provide on-site support for the commissioning of systems.
CPPcheck Solutions is our partner for carrying out static code analyses as part of safety and/or security projects in accordance with IEC62443, IEC61508, EN50716/EN50128 and ISO26262, for example.
The tool is also available as an open source version and guarantees efficient static code analyses. CPPCheck offers rule sets for MISRA-C, MISRA-C++, SEI CERT and others.
