IEC 61400-22:2010

Wind turbines - Part 22: Conformity testing and certification

IEC 61400-22:2010 was withdrawn on 2018-08-31, and replaced with the deliverables for the wind sector (WE-OMC) contained in the IECRE Conformity Assessment System.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

Eoliennes - Partie 22: Essais de conformité et certification

La CEI 61400-22:2010 définit les règles et procédures d'un système de certification des éoliennes comprenant la certification de type et la certification des projets d'éoliennes installées sur terre ou en mer. Ce système spécifie les règles relatives aux procédures et à la gestion de mise en oeuvre de l'évaluation de la conformité d'une éolienne et des parcs éoliens, avec les normes spécifiques et autres exigences techniques en matière de sécurité, de fiabilité, de performances, d'essais et d'interaction avec les réseaux électriques.

WIND TURBINES –



Part 22: Conformity testing and certification





FOREWORD


1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61400-22 has been prepared by IEC technical committee 88: Wind

turbines.
This standard cancels and replaces IEC WT 01 (2001): IEC System for Conformity Testing
and Certification of Wind Turbines – Rules and Procedures.
The text of this standard is based on the following documents:
FDIS Report on voting
88/365/FDIS 88/368/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be

• reconfirmed,

• withdrawn,


• replaced by a revised edition, or

• amended.

INTRODUCTION


This International Standard defines rules and procedures for conformity testing and

certification of wind turbines with respect to standards and technical requirements for wind

turbines and wind farms. It is intended to facilitate mutual recognition (reciprocal acceptance)

by participants of test results and certificates issued by other participants for obtaining

certification at national level and operates within the scope of the IEC 61400 series of

standards and technical specifications for wind turbines.


The certification procedures in this standard constitute a complete third party conformity

evaluation of a wind turbine type, a major component type or one or more wind turbines at a

specific location.
In addition to design verification and testing, this standard provides information for the
recognition of or assessment for approval of the supplier's quality system, regular surveillance
through inspection of the supplier's quality system and quality plans, and audit testing of
samples. The standard is amongst others intended to result in significant benefit to the
applicant by reducing the number of steps necessary to obtain certification or approval at
national level.
