application guide safety relays from riese electronic page 9 C Standards-overview 1 Standards-overview The following information applies only to the European machinery directive. The main requirement of the European machinery directive is, that there is no risk for persons (and, where appropriate, pets and goods) health and safety if the machine is properly installed, maintained and used according to the regulations. Machines have to be conform with their machine type corresponding basic-, safety- and health requirement, according to the 1st appendix of the European machinery directive. The term “used according to the regulations” is defined in DIN EN ISO 12100 part 1. The complete 1st appendix of the European machinery directive is attached to DIN EN ISO 12100 as appendix A. The 1st appendix of the European machinery directive contains the requirements for a machine safety concept. For the not abolished dangers have to be made the necessary protection measures. Only for the not abolished residual risks, a fallback on specialized training and protective equipment are allowed. 1.1 Standards-types The European safety standards are hierarchically structured. There are the standards type A, B1, B2 and C. Type A - Standards (basic safety standards) They include basic ideas, design principles and general aspects for devices and systems. Examples: DIN EN ISO 12100 1/2 Safety of machines – basic ideas, general design principles EN 1050 Safety of machines – risk evaluation principles no longer valid, replaced by EN ISO 14121-1 EN ISO 14121-1 Safety of machines – part 1: Principles, replacement for EN 1050 EN/IEC 61508 Functional safety of safety-related electrical, electronical and programmable electronical systems. Type B - Standards (safety group standards) Type B standards refer to safety aspects or safety-critical setups. They can be used for a whole series of machines, devices and systems.
