Scope of application

General

This specification applies to type certification of wind turbines as well as for component certification. Component certification as a term used in this service specification covers e.g. major and minor components, systems, single parts or assemblies used in a wind turbine or attached to it. The mandatory certification modules comprise design, manufacturing and testing at different stages of the wind turbine development process. An overview of the certification modules is given in Sec.2 and a more detailed description is given in Sec.3.

This specification together with referred DNV standards and recommended practices represents a completely revised and expanded version of GL-IV-1 and GL-IV-2; both with a history of 30 years.

The services described in [1.3.2] - [1.3.11] below are optional services related to type and component certification. They may be added to component or type certification to extend the use of respective certificates by e.g. adding more options or markets.
