IEC TR 62131-1:2011

Environmental conditions - Vibration and shock of electrotechnical equipment - Part 1: Process for validation of dynamic data

IEC/TR 62131-1:2011(E) reviews the essentially empirical data validation procedure adopted to establish confidence in the data utilized by the other Parts of IEC/TR 62131. The adoption of a validation procedure was necessary, due the lack of fully validated data sets. This technical report is intended to be generic in nature and is normally expected to be adopted as far as is practical within the circumstances of any particular data item.

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 mÈade 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 62131-1, which is a technical report, has been prepared by IEC technical committee
104: Environmental conditions, classification and methods of test.

INTRODUCTION
A major reservation, identified early in the work of IEC technical committee 104 (working
group 15) to collate dynamic environmental data, was the lack of fully validated data sets. In
the absence of fully validated dynamic information, an essentially empirical data validation
procedure has had to be adopted. The process set out in this technical report is intended to
be generic in nature and is normally expected to be adopted as far as is practical within the
circumstances of any particular data item.
In most cases, a fully quantified validation approach is not possible; as a consequence, the
alternative approach set out in this technical report has been adopted. The approach is
fundamentally an exercise in building confidence that the data were acquired and analysed in
a competent manner. Such confidence is essential if the data is to form a reasonable basis for
establishing trends and quantifying environmental conditions. A fundamental consequence of
the absence of fully validated data sets is that no single data set can be entirely relied upon to
quantify a
