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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 61948-1, which is a technical report, has been prepared by subcommittee 62C:
Equipment for radiotherapy, nuclear medicine and radiation dosimetry, of IEC technical
committee 62: Electrical equipment in medical practice.
This second edition cancels and replaces the first edition published in 2001. This edition
constitutes a technical revision and includes the following significant technical changes with
respect to the previous edition:
a) Geiger-Mueller counters are explicitly excluded from the scope;

---------------------- Page: 5 ----------------------
– 4 – IEC TR 61948-1:2016  IEC 2016
b) the routine test for energy calibration has been split into a test for energy calibration
(frequency: daily) and a test for energy calibration linearity (frequency: semi-annual);
c) the test for window presets has been removed.

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.

HYDRAULIC TURBINES, STORAGE PUMPS AND PUMP TURBINES –
TENDERING DOCUMENTS –
Part 1: General and annexes
0 Introduction
The application of hydraulic machines to a specific project is made from design criteria
uniquely adapted to that particular site. Accordingly, the possibility of using identical machines
from one site to another is usually remote because of many variations in basic design and
operating conditions. For this reason, it is not feasible in a single publication of this type to
develop standard documents which cover a wide range of site specific applications or to
specify in detail the various machine types. However, the technical report will assist in
preparation of Tendering Documents (TD) through the use of a common layout which takes
advantage of uniformity and the time-saving features of word processing software. A uniform
approach of the type proposed will make it easier for the Employer to prepare the Tendering
Documents and for the Tenderer to prepare its proposal.
The report outlines the various chapters needed for a complete set of Tendering Documents,
together with comments on the purpose of each and discussions as necessary. The guide is
intended to assist in making certain that information is placed in the appropriate section;
thereby avoiding possible conflict or duplication. This results in a greater degree of
completeness in the documents and adds to their adaptability and ease of updating while
minimizing misinterpretations.
The main objective for inviting competitive tenders for hydraulic machines is to purchase the
most economical equipment which will meet the performance requirements of the specific site.
The capital investment in machinery is a significant one; it can range from 20 % to 50 % of
project costs. The value of machine performance becomes an important item of concern in the
purchasing process. This guide contains some information on methods of evaluation and
means of establishing performance criteria to assist in achieving optimum equipment selection.
In preparing Tendering Documents, cognisance should be taken of problems which may be
encountered by unnecessarily restrictive specifications, particularly when applied to machines
of small to moderate sizes within the range covered by the guide. Restrictive requirements may
add significantly to the cost of the equipment without a proportional gain in its reliability or
performance. It is important therefore that Tendering Documents properly define and describe,
in an effective manner, the specific conditions of operation, size, number of units to be
installed, and special features required, if any.
Tendering Documents which require an inordinate amount of information from Tenderers can
also unnecessarily increase the costs for preparing and evaluating tenders. This may also
unnecessarily restrict the successful Contractor's freedom to apply an optimal design and may
deter the Tenderer from tendering at all. Information requested in the technical data sheets,
therefore, should be limited to that which is really essential for evaluation and comparison of
tenders by the Employer and engineer.
In conclusion, this guide should not be used to replace the engineering effort needed in the
selection, design, manufacturing, installation, and testing of the machines and associated
systems; nor does it contain complete detailed specifications and descriptions of conditions or
components. It is assumed that qualified engineering personnel will be engaged on the project
to undertake the necessary evaluation of site conditions and selection of equipment which will
meet the performance, operation, reliability, and maintainability criteria established for the
project.

1 Scope and object
This technical report, referred to herein as the "Guide", is intended to assist in the preparation
of Tendering Documents and tendering proposals and in the evaluation of tenders for hydraulic
machines.
The object of this technical report is to provide a general guide for preparation of Tendering
Documents (TD) for the supply, installation and testing of hydraulic turbines, storage pumps,
and pump-turbines herein referred to as hydraulic machines as defined in 2.2 of this
publication. This technical report considers the case where both equipment supply and site
installation are carried out by the same Contractor. In those cases where site installation is not
included in the scope of work, the Tendering Documents should include supplementary
provisions for site supervisory services to be provided by the equipment supply Contractor and
for day-to-day interface with the site installation Contractor.
Hydraulic machines for small units with power less than 5 MW and with runner/impeller
diameters less than 3 m are covered in IEC 61116. These limitations are not intended to be
absolute and will depend on the type of machine and on other project characteristics.
2 Reference documents and definitions
2.1 Reference documents
2.1.1 Application of reference documents
The adoption of reference documents can greatly assist users of this guide by avoiding
unnecessary duplication of standards and codes which have gained industry acceptance. There
are a number of sources for reference documents such as IEC, ISO, regional or national
standards, and other recognized standards. It is strongly recommended that users take
advantage of such standard documents in preference to developing new versions for similar
requirements. The Employer should be prepared to provide copies of non-international
standards to the Tenderers and/or the Contractors upon request.
2.1.2 IEC publications
IEC publications (in their latest revision), as they apply, should be used and referenced in the
preparation of Tendering Documents and the related technical specifications. The list of
IEC publications relating to hydraulic machinery is as follows:
IEC 60027 (all parts), Letter symbols to be used in electrical technology
IEC 60041:1992, Field acceptance tests to determine the hydraulic performance of hydraulic
turbines, storage pumps and pump-turbines
IEC 60617 (all parts), Graphical symbols for diagrams
IEC 60193,— Model acceptance tests to determine the hydraulic performance of hydraulic
turbines, storage pumps and pump-turbines (to be published)

In addition to IEC publications, numerous internationally accepted recommendations have been
prepared by ISO, some of which may apply to specific items. If a contradiction is found
between IEC standards and ISO standards, the IEC standards shall govern.
2.1.4 National standards
Where no applicable international standards exist, regional and/or national standards should be
used in preference to developing unique requirements. In this connection, where equivalence
of national standards has been previously established by the Employer, this equivalence should
be accepted for subsequent projects.
Where national standards are mandatory by law, such requirements shall be specified in the
documents. The Employer should provide copies of mandatory standards to Tenderers and/or
Contractors upon request or specify where such standards may be obtained.
2.2 Definitions
The following definitions apply to this guide:
Words for which definitions are given in IEC publications shall be used only with the meanings
defined by IEC. No other definitions shall be used for such words.
