Regulations and standards1.2 Safety of machinery in Europe10/151-17© Siemens AG 2015 All Rights ReservedSINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) -- 10.2015 Edition1.2.1 Machinery directive (2006/42/EC)With the introduction of a European Economic Area, a decision was made that thedomestic standards and regulations of all of the EEA Member States – that areinvolved with the technical implementation of machines -- would be harmonized.This means that the machinery directive had to be implemented -- as an internalmarket directive -- as far as the content was concerned -- in the domestic legisla-tion of the individual Member States. For the Machinery Directive, this was realizedwith the aim of achieving standard safety objectives and, in turn, removing techni-cal trade barriers. Corresponding to its definition ”a machine is an assembly of lin-ked parts or components -- at least one of which moves”, this directive is extremelyextensive. With the revised version from 2006, the range of applications has beenexpanded to include, among other things, ”Logic units for safety functions”.The machinery directive involves the implementation of machines. The basic safetyand health requirements specified in Annex I of the Directive must be fulfilled forthe safety of machines.The protective goals must be responsibly implemented in order to fulfill the require-ments for conformity with the directive.The manufacturer of a machine must provide proof that his machine is in com-pliance with the basic requirements. This verification is facilitated by means of har-monized standards.1.2.2 Harmonized European standardsThe two Standards Organizations CEN (Comité Européen de Normalisation) andCENELEC (Comité Européen de Normalisation Électrotechnique), mandated bythe EU Commission, drew--up harmonized European standards in order to preci-sely specify the requirements of the EC directives for a specific product. Thesestandards (EN standards) are published in the official journal of the commission ofthe European Parliament and Council and must be included without revision in do-mestic standards. They are designed to fulfill basic health and safety requirementsas well as the protective goals specified in Annex I of the Machinery Directive.When the harmonized standards are complied with, then there is an ”automaticassumption” that the directive is fulfilled. This means that the manufacturer maythen assume that he has complied with the safety aspects of the directive underthe assumption that they are also handled in that particular standard. However, notevery European Standard is harmonized in this sense. Key here is the listing in theofficial journal of the commission of the European Parliament and Council.
