    22、 Tests and guidance Combined climatic (temperature/humidity) and dynamic (vibration/shock) tests FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object o

    23、f 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 (

    24、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 w

    25、ith 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

    26、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

    27、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 Commit

    28、tees 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 provid

    29、e 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 lates

    30、t 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, wheth

    31、er 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 ind

    32、ispensable 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 6006

    33、8-2-53 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 6006

    34、8-2-53, 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

    35、or shocks, with different tests for climatic conditions cold, dry heat, change of temperature or constant and cyclic damp heat. 4 60068-2-53 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 104/499/FDIS 104/514/RVD Full information on the voting for the a

    36、pproval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60068 series, under the general title Environmental testing, can be found on the IEC web

    37、site. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by

    38、a revised edition, or amended. 60068-2-53 IEC:2010 5 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, tran

    39、sport 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

    40、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 e

    41、nvironmental 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, h

    42、umidity and vibration occurs especially in the domains of automotive, rail and aerospace environments. 6 60068-2-53 IEC:2010 ENVIRONMENTAL TESTING Part 2-53: Tests and guidance Combined climatic (temperature/humidity) and dynamic (vibration/shock) tests 1 Scope This part of IEC 60068 provides a desc

    43、ription 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. The method of combined tests dete
