Foreword

The text of document 2/1257/FDIS, future edition 3 of IEC 60034-14, prepared by IEC TC 2, Rotating

machinery, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as

EN 60034-14 on 2003-12-01.
This European Standard supersedes EN 60034-14:1996.
The significant technical changes with respect to the previous edition are:

a) reduced vibration levels of new machines during factory acceptance tests; the new levels are

based on a combination of displacement, velocity and acceleration rather than only velocity;

b) the speed range is extended;
c) the number of shaft-height ranges is reduced;
d) a procedure for testing vertical motors has been introduced.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-12-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice

The text of the International Standard IEC 60034-14:2003 was approved by CENELEC as a European

Standard without any modification.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 60034-14 has been prepared by IEC technical committee 2:

Rotating machinery.

This third edition cancels and replaces the second edition published in 1996. The significant

technical changes with respect to the previous edition are:

a) reduced vibration levels of new machines during factory acceptance tests; the new levels

are based on a combination of displacement, velocity and acceleration rather than only

velocity;
b) the number of shaft-height ranges is reduced;
c) procedures for testing vertical motors have been reduced.
