Practical use of IEC 61508 and EN 954 for the safety evaluation of an automatic mining truck

This paper presents the general content and results of a safety program and comments on its application. The safety file, which was used to support the safety assessment of an automatic mining truck system, was developed in accordance with the general requirements of a standard of the International Electrotechnical Commission for the functional safety of safety-related systems, and using some parts of the European standard for control systems. Conclusions on the assessed system and on the use of the methodology in similar applications are presented.
