HYDRAULIC TURBINES, STORAGE PUMPS AND PUMP-TURBINES –
TENDERING DOCUMENTS –
Part 6: Guidelines for technical specifications
for pump-turbines
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an International
Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where for any other reason
there is the future but no immediate possibility of an agreement on an International
Standard;
• type 3, when a technical committee has collected data of a different kind from that which is
normally published as an International Standard, for example "state of the art".
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to be
no longer valid or useful.
IEC 61366-6, which is a technical report of type 3, has been prepared by IEC technical
committee 4: Hydraulic turbines.

Committee draft Report on voting
4/110/CDV 4/122/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
Technical Report IEC 61366-6 is one of a series which deals with Tendering Documents for
hydraulic turbines, storage pumps and pump-turbines. The series consists of seven parts:
IEC 61366-1: General and annexes (IEC 61366-1)
Part 2: Guidelines for technical specification for Francis turbines (IEC 61366-2)
Part 3: Guidelines for technical specification for Pelton turbines (IEC 61366-3)
Part 4: Guidelines for technical specification for Kaplan and propeller turbines (IEC 61366-4)
Part 5: Guidelines for technical specification for tubular turbines (IEC 61366-5)
Part 6: Guidelines for technical specification for pump-turbines (IEC 61366-6)
Part 7: Guidelines for technical specification for storage pumps (IEC 61366-7)
Parts 2 to 7 are "stand-alone" publications which when used with IEC 61366-1 contain
guidelines for a specific machine type (i.e. Parts 1 and 4 represent the combined guide for
Kaplan and propeller turbines). A summary of the proposed contents for a typical set of
Tendering Documents is given in the
