Environmental testing - Part 2-53: Tests and guidance: Combined climatic (temperature/humidity) and dynamic (vibration/shock) tests (IEC 60068-2-53:2010)

IEC 60068-2-53:2010 provides a description of test methods and guidance for testing equipment or components under combined climatic and dynamic conditions. The purpose of combined testing is to investigate to what extent the equipment or components are affected by combined climatic and dynamic tests. This second edition cancels and replaces the first edition of IEC 60068-2-50, published in 1983, the first edition of IEC 60068-2-51, published in 1983 and the first edition of 60068-2-53, published in 1984 and constitutes a technical revision. The main changes with respect to the previous editions of all three standards cited above is to update and group tests. In this way it allows for the possibility to use different kinds of vibration excitation:  - sine, random or mixed mode;  - or shocks, with different tests for climatic conditions;  - cold, dry heat, change of temperature or constant and cyclic damp heat.

Overview

EN 60068-2-53:2010 (IEC 60068-2-53:2010) is a CLC harmonized standard that defines test methods and guidance for combined climatic (temperature/humidity) and dynamic (vibration/shock) tests. Its purpose is to evaluate how equipment and components respond when exposed simultaneously to environmental stresses such as cold, dry heat, temperature change or damp heat together with vibration (sine, random or mixed mode) or shocks. This second edition consolidates and updates earlier IEC parts (60068-2-50, -2-51, -2-53) to allow flexible combinations of climatic and dynamic excitations.

Key topics and requirements

• Combined testing scope: Describes procedures for applying climatic conditions together with dynamic excitation to detect electrical, mechanical or other physical changes.
• Types of dynamic excitation: Supports sine, broadband random, mixed-mode vibration, and shock testing as part of combined sequences.
• Climatic conditions: Includes cold, dry heat, change of temperature, and damp heat (constant and cyclic).
• Test selection and parameters: Requires specification of parameters such as temperature levels, exposure times, vibration type and severity, number and repetition of shocks, axis of excitation and specimen operating condition. These parameters are to be selected from the relevant IEC 60068-2 standards or project specification.
• Measurement and reporting: Calls for initial and final functional measurements and clear test-reporting data so effects of combined stresses can be assessed.
• Guidance and examples: Informative annexes offer example test sequences and recommended set-ups for practical implementation.

Applications and who uses it

• Manufacturers and test laboratories performing environmental testing on electronic and electromechanical products.
• Product, reliability and test engineers in automotive, rail, aerospace, defence, telecommunications and industrial electronics who need to validate performance under realistic operational and transport environments.
• Quality assurance, regulatory and procurement teams requiring documented methods for combined climatic/dynamic qualification or ruggedness testing.
• Designers seeking to identify failure modes induced by simultaneous thermal/humidity and mechanical stresses.

Practical value

• Helps simulate real-world combined stresses to reveal interactions (e.g., moisture-assisted mechanical degradation, thermal cycling effects under vibration).
• Enables standardized, repeatable tests for product qualification, supplier acceptance and comparative benchmarking.
• Supports risk reduction by identifying weaknesses early in design or in component selection.

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 60068-2-53 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This second edition cancels and replaces
– the first edition of IEC 60068-2-50, published in 1983,
– the first edition of IEC 60068-2-51, published in 1983 and
– the first edition of 60068-2-53, published in 1984
and constitutes a technical revision.
The main changes with respect to the previous editions of all three standards cited above is to
update and group tests. In this way it allows for the possibility to use different kinds of
vibration excitation – sine, random or mixed mode – or shocks, with different tests for climatic
conditions – cold, dry heat, change of temperature or constant and cyclic damp heat.

INTRODUCTION
Equipment and components are required to function without significant reduction in
performance when subjected to different environmental parameters.
The type and severity of the environmental parameters depend on the operational, transport
and storage environments to which the equipment and components are subjected. The
environmental effects on the performance of equipments in the tropics and subtropics are
totally different from those in arctic regions. Individual parameters cause a variety of different
and overlapping effects on the equipment and components.
The manufacturer attempts to ensure, and the user expects, that equipment and components will
survive the environments to which they will be subjected throughout their useful life. This
expectation can be assessed by exposure of the specimen to a range of simulated environmental
parameters controlled in the laboratory. The severity of the environmental parameters is often
increased to obtain meaningful results in a relatively short period of time. This allows
assessment of the likely effects of applied environmental conditions.
The combination of temperature, humidity and vibration occurs especially in the domains of
automotive, rail and aerospace environments.
