5th European conference on standardization, testing and certification in the field of occupational safety and health (OHS). The conference will be held in Seville on 14-16 October 2015. It is aimed at European and national authorities, users and manufacturers of products, OHS experts, and other stakeholders having an interest in health and safety at work. The focus of the 5th conference organised by the EUROSHNET network will be on the need to create conditions for improving the quality of working life in a rapidly changing world: how can standardization, testing and certication contribute? Which pitfalls should be avoided? With your support and cooperation we shall find ways to complete the jigsaw puzzle of the numerous – and sometimes contradictory – requirements that we must face in the next 10 years.
