DIN IEC/TS 61400-31:2024-12

The Technical Specification This document covers risk due to internal or external causes, such as technical failures, human errors, extreme wind conditions, turbine icing, lightning strikes, earthquakes, flooding, landslides or fire. However, the specific cause of an incident (for example, an incident such as a turbine collapse) is irrelevant to the assessment of the consequences. The only relevant factor is the expected probability of occurrence for the incident considered. The Technical Specification covers only onshore wind turbines with a horizontal axis and a swept area greater than 200 m<(hoch)2. With regard to the extent of damage, this Technical Specification is limited to immediate, potentially fatal physical damage. It does not cover occupational exposure, for example personnel involved in the operation and maintenance of the turbine, since occupational risks are usually dealt with in occupational health and safety regulations. The risk of damage to structures or other objects is also not part of this Technical Specification unless such damage in turn poses a risk to the public.
