23、cal 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
24、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 Co
25、mmittee 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
26、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 al
27、l 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 r
28、esponsible 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 diver
29、gence 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 m
30、arks 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 expe
31、rts 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 P
32、ublication 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 P
33、ublication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61747-10-1 has been prepared by IEC technical committee 110: Electronic display devices. This first edition of IEC 61747-10-1 cancels and replac
34、es Clauses 1 and 2 of the first edition of IEC 61747-5 published in 1998. This edition constitutes a technical revision. NOTE It is intended that the other clauses of IEC 61747-5:1998 will be replaced by new parts in the IEC 61747 series. The details of the intended changes are given in Annex D of I
35、EC 61747-30-1:2012. 4 61747-10-1 IEC:2013 The text of this standard is based on the following documents: CDV Report on voting 110/395/CDV 110/454/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication h
36、as been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61747 series, published under the general title Liquid crystal display devices can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of
37、 existing standards in this series will be updated at the time of the next edition. 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 publicati
38、on. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61747-10-1 IEC:2013 5 LIQUID CRYSTAL DISPLAY DEVICES Part 10-1: Environmental, endurance and mechanical test methods Mechanical 1 Scope This part of IEC 61747 lists test methods applicable to
39、 liquid crystal display devices. It takes into account, wherever possible, the mechanical robustness test methods as outlined in IEC 60068. NOTE Devices include cells and modules. The object of this standard is to establish uniform preferred test methods with preferred values for stress levels for j
40、udging the mechanical properties of liquid crystal display devices. In case of contradiction between this standard and a relevant specification, it is the latter that should govern. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and a
