GUIDELINES FOR COMMISSIONING AND OPERATION OF HYDRAULIC
TURBINES, PUMP-TURBINES AND STORAGE PUMPS

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 60545 has been prepared by IEC technical committee 4: Hydraulic
turbines.
This second edition cancels and replaces the first edition published in 1976 and the first edition
of IEC 60805 published in 1985. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the focus is on the commissioning and operation of the hydraulic machine. Interfaces to the
electric machine are mentioned only for a better understanding of the context;
b) the definitions of tests for commissioning and adjustable speed are updated to state of the
art;
c) the record sheets ‘measurements during erection’ are excluded (see IEC 63132 (all parts);
d) the maintenance is excluded (see IEC 62256).

GUIDELINES FOR COMMISSIONING AND OPERATION OF HYDRAULIC
TURBINES, PUMP-TURBINES AND STORAGE PUMPS



1 Scope
The purpose of this document is to establish, in a general way, suitable procedures for
commissioning and operation of hydraulic machines and associated equipment, and to indicate
how such machines and equipment should be commissioned and operated.
Commissioning and operation of the associated equipment are not described in detail in this
document but is considered in the commissioning and operation procedure as a separate step.
Machines of up to about 15 MW and reference diameters of about 3 m are generally covered
by IEC 62006.
It is understood that a guideline of this type will be binding only if the contracting parties have
agreed upon it.
The guidelines exclude matters of purely commercial interest, except those inextricably
connected with the conduct of commissioning and operation.
The guidelines are not concerned with waterways, gates, drainage pumps, cooling-water
equipment, generators, motor-generators, electrical equipment (e.g. circuit breakers,
transformers) etc., except where they cannot be separated from the hydraulic machinery and
its equipment.
Wherever the guidelines specify that documents, drawings or information are supplied by a
supplier (or by suppliers), each individual supplier should furnish the appropriate information
for its own supply only.
2 Normative references
There are no normative references in this document.
