Those persons working with and at the certain machines mustn't suffer from a physical damage. Therefore the European Union (EU) outlined a coherent preventive security concept for machinery. The essential regulations of the EU rules for safety and health requirements were laid down by the Parliament and the European Council of the EU in the Machinery Directive 2006/42/EC. The harmonized European Standards (ES) developed by the standardization body CEN are intended to implement these essential safety and health requirements comprised in the Annex. These requirements have to be met by the manufacturer due to the principle of the risk assessment in the design and construction processes; moreover they have to be specified within EC conformity declaration and technical documentation of the machines.
