The article analyzes the current regulatory framework for proof of safety, quality assurance, and confi rmation of the conformity of microprocessor-based railway automation and remote control systems in the EAEU. CENELEC standards are briefl y discussed. A brief overview is provided as regards measures to ensure the required level of safety of microprocessor-based railway automation and remote control systems from the point of view of quality management of development, safety management, and confi rmation of the proper functioning of microprocessor systems. The practice of confi rming the railway transport automated process control systems comply with standards in the form of a declaration of conformity per TR CU 003/2011 has been analyzed. It is concluded that there is a need to develop a regulatory framework to ensure regulated analysis and assessment of railway automation and remote control systems following the requirements of functional safety, as well as further development of standardization documents to regulate methods for assessing functional safety.

Safety is always the key issue in automotive industry. The adoption of hi-tech automotive applications requires not only the development of reliable electrical/electronic/programmable electronic (E/E/PE) systems and communication protocols, but also an evolution in functional safety process management. ISO/WD 26262, the adaption of IEC 61508 for road vehicles, provides guidelines and standardized measurements for functional safety. This paper discusses how automotive microcontroller suppliers can deal with this new challenge by integrating functional safety management into product design and development. An ISO/WD 26262-compliant functional safety management flow is proposed, with specifications on techniques of corresponding safety assessment.

This paper describes a systematic way to apply the functional safety standards IEC 61508 and IEC 61511 on the safety management of a chemical process tank. After a short introduction of the basic principle of the functional safety philosophy the risk based determination of the safety integrity level (SIL) for a special liquid tank application is given. Then a safety instrumented system (SIS) suitable to the SIL-level 2 has been designed to fulfill the qualitative and quantitative requirements in the safety standards. The experience gained can be seen as a guidance for process and I&C engineers in industrial practice.
