Information on safety standards / the Machine Directive
|
CE mark
Machine builders that commission a machine in Europe must issue an EC declaration of conformity according to the Machine Directive 2006/42/EG. The new Machinery Directive took effect in all member states of the European Union on 29 December 2009, thereby replacing the "old" Machinery Directive (98/38/EC).
In Germany, for example, the change took effect with the 9th publication of the Equipment and Product Safety Act.
The Machinery Directive also includes standards for the functional safety of machines and equipment.
ISO 14121:
One important point is the risk assessment, which must be carried out. ISO 14121 outlines the basic process.
ISO 12100:
ISO 12100 defines the basic concepts and general principles for designing machines. Measures for reducing risks are also handled in this standard. Such measures many include: intrinsically safe construction, protective elements or user information.
ISO 13849:
When protective elements are required, ISO 13849 prescribes how these must be designed. A risk graph determines the required performance level. Based on this, the necessary safety functions are drafted by choosing a suitable architecture and the right components. Finally, whether the measures suffice to fulfill the required performance level must be verified.
In the machine's development folder, the risk assessment and measures taken to achieve the necessary safety requirements must be documented and saved.
Here you have an overview of the most important safety-related standards and their implementation.
