IEC SYSTEM FOR CONFORMITY TESTING AND CERTIFICATION
OF WIND TURBINES –
RULES AND PROCEDURES
FOREWORD
This publication has been prepared by TC 88: Wind turbine systems, and has been approved
by the Conformity Assessment Board (CAB). It defines a certification system for wind
turbines.
It specifies rules of procedure and management for carrying out conformity evaluation with
respect to standards and technical requirements for wind turbines. This document is intended
to be used with other technical standards and normative documents and, where necessary,
technical requirements and test procedures are specified.
Compliance with this system does not relieve any person, organisation or corporation of the
responsibility for observing other applicable regulations.
The text of this publication is based on the following documents:

INTRODUCTION
NOTE This INTRODUCTION provides an overview of the IEC WT System and is not part of the Rules.
The international scheme for recognition of results of testing to standards for wind turbines is
operated by the IEC, and known as the IEC WT System. The IEC WT System is based on the
principle of 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 for wind turbines.
In addition to type testing, the IEC WT System provides for the recognition of or assessment
for approval of the manufacturer's quality system, regular surveillance through inspection of
the manufacturer's factory quality system and product quality plans, and audit testing of
samples from the manufacturer's factory. The System is intended to result in significant
benefit to the manufacturer by reducing the
