VDMA-Specifications on Functional Safety

MAN

Due to the fact that existing standards are either generic or address different target groups various experts met under the umbrella of VDMA with the goal to implement the new requirements for turbomachinery with regard to Functional Safety.

Turbomachinery in power plants and industrial plants has to meet high safety requirements. Given that there was recognised a tendency to apply more and more electric and electronic components in safety functions the necessity to develop standards for Functional Safety was identified.

Due to the fact that existing standards are either generic (IEC 61508) or address different target groups (IEC 61511 for process industry, IEC 62061 and ISO 13849 for machinery), experts of VDMA Members companies suported by experts from VGB, the leading technical association of European utilities, met under the umbrella of VDMA with the goal to implement the new requirements for turbomachinery with regard to Functional Safety.

The following VDMA Specifications were developed:

  • 4315-1 - Turbomachinery and generators – Application of the principles of functional safety - Part 1: Methods for determination of the necessary risk reductionMethods for determination of the necessary risk reduction
  • 4315-2 – Part 2: Risk assessment Existing installations
  • 4315-5 – Part 5: Risk assessment Steam Turbines
  • 4315-6 – Part 6: Risk assessment Gas Turbines
  • 4315-7 – Part 7: Risk assessment Compresor train
  • 4315-8 – Part 8: Risk assessment Generators
