Developing a framework for addressing human factors in IEC 61508

IEC 61508 is a key international standard in establishing requirements for electrical, electronic and programmable electronic systems in safety-related applications. It addresses hardware and software-components of safety-related systems from initial specification, through design, operation and eventually disposal. In a number of places the standard recognises the need to address human factors. Therefore, a project was undertaken to explore how guidance can be structured to link human factors requirements into IEC 61508
