IEC 61400-22:2010 was withdrawn on 2018-08-31, and replaced with the deliverables for the wind sector (WE-OMC) contained in the IECRE Conformity Assessment System. More information available here.

IEC 61400-22:2010 defines rules and procedures for a certification system for wind turbines (WT) that comprises both type certification and certification of wind turbine projects installed on land or off-shore. This system specifies rules for procedures and management for carrying out conformity evaluation of WT and wind farms, with respect to specific standards and other technical requirements, relating to safety, reliability, performance, testing and interaction with electrical power networks.
