Functional Safety of Machinery

TÜV Rheinland China - TÜV Rheinland

This vocational qualification training of the TÜV Rheinland Functional Safety Training Program supports engineers (and/or persons working in functional safety business) to deepen their knowledge and their experience in order to achieve a worldwide acknowledged know how and practical experience within the area of functional safety according to the international standards ISO 13849 and IEC 62061.

Engineers who are working in the field of functional safety for many years have the possibility to obtain an official verification of their expertise. By passing a final exam successfully they will receive a Functional Safety Engineer (TÜV Rheinland) certificate.

The standards regarding Functional Safety require that persons and organisations performing responsible (accountable) tasks during the life cycle phase of a machine have to acquire and prove their competencies in Machine Safety.

Within this training the requirements for the design as well as the proof of Functional Safety for Machinery applications are described and discussed in detail based on the relevant current standards.

The selection of protective devices for Machinery in order to achieve the required risk reduction is shown. Examples of safety functions are explained. The main requirements of ISO 13849 and IEC 62061 for the design of safety related parts of machine control systems are presented and application examples illustrating the quantitative assessment of safety functions are discussed.

Target Group

Application engineers and system integrators with some experience in Functional Safety; also designers and safety specialists working in Machinery applications.
