Full title and description

St IEC 61400-22-2010 — Wind turbines — Part 22: Conformity testing and certification. This international standard establishes the rules, procedures and management requirements for a certification system covering both type certification of wind turbine models and project (site) certification for wind turbine installations onshore and offshore. It defines documentation, assessment and surveillance processes and requirements for certification bodies, testing laboratories and applicants.

Abstract

IEC 61400-22:2010 provides a framework for independent conformity assessment of wind turbines and wind farms against applicable technical standards and other requirements related to safety, reliability, performance, testing and grid interaction. The standard describes the elements of a certification system, procedures for type and project certification, ongoing conformity surveillance and the information applicants must supply for assessment. It was later withdrawn and its conformity-assessment functions were superseded by the IECRE Conformity Assessment System.

Scope

The standard specifies rules and procedures for a certification system for wind turbines that covers both type certification of turbine designs and certification of wind turbine projects (site/project certification) for onshore and offshore installations. It addresses the organization and management of conformity assessment, the duties and requirements for certification bodies and test laboratories, documentation to be supplied by applicants, surveillance and procedures to verify conformity with the relevant technical standards and requirements. The text is not limited to a particular size or design of turbine, although it notes provisions that may apply specifically to small wind turbines.

Key topics and requirements

• Definition of elements and structure of a wind-turbine certification system (type and project certification).
• Procedures for conformity assessment, including assessment steps, testing and evidence requirements.
• Requirements for surveillance, re-assessment and maintenance of certificates.
• Documentation and information to be provided by applicants (technical data, test reports, drawings, quality evidence).
• Criteria and requirements for certification bodies, inspecting/ testing laboratories and their competence.
• Application to onshore and offshore wind turbine projects and notes on small wind turbine provisions.

The list above summarizes the principal requirements and topic areas defined in the standard.

Typical use and users

Used by certification bodies, conformity assessment organizations, wind turbine manufacturers, project developers, test laboratories, national regulators and independent assessors. The standard served as the reference for establishing and operating independent certification schemes, supporting procurement, financing and regulatory acceptance of wind turbines and wind farms. After withdrawal, many certification activities moved to the IECRE Conformity Assessment System while the technical parts of the IEC 61400 series continue to be referenced for technical requirements.

Related standards

Part of the IEC 61400 series (design, measurement and testing of wind turbines), notably referenced alongside IEC 61400-1 (design requirements), IEC 61400-12 (power performance measurement), IEC 61400-21 (measurement of mechanical loads/noise assessment aspects) and the broader IECRE conformity-assessment deliverables that have superseded the procedural elements of 61400-22. Historical predecessor documents include earlier WT-type certification guidance (WT 01).
