30、ng devices 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 standardiza
31、tion 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
32、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 In
33、ternational 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 sin
34、ce 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
35、 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
36、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 a
37、ssessment 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, e
38、mployees, 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
39、 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 t
40、he 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 60297-3-109 has been prepared by subcommittee 48D: Mechanical structures for electrical an
41、d electronic equipment, of IEC technical committee 48: Electrical connectors and mechanical structures for electrical and electronic equipment. The text of this standard is based on the following documents: FDIS Report on voting 48D/598/FDIS 48D/602/RVD Full information on the voting for the approva
42、l 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. BS EN 60297-3-109:2016IEC 60297-3-109:2015 IEC 2015 5 A list of all parts in the IEC 60297-3 series, published under the general
43、title Mechanical structures for electrical and electronic equipment Dimensions of mechanical structures of the 482,6 mm (19 in) series, can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will b
44、e 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 website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be
45、reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 60297-3-109:2016 6 IEC 60297-3-109:2015 IEC 2015 INTRODUCTION The main applications for embedded computing devices are in machine control, medical, transportation, aerospace and communication environments. For such applications
46、 single board computers are typically used. In order to meet the different environmental conditions and handling requirements, single board computers require for mechanical, thermal and environmental protection by means of appropriate chassis designs. These devices currently reflect a very fragmente
47、d situation in the view of any existing mechanical structures dimensional standard. Due to the lack of standardization the individual solutions are realized with proprietary dimensions. The rapidly growing market for single board computing devices calls for dimensional coordination of chassis and as
48、sociated printed boards, in order to replace proprietary solutions. This standard will establish a three dimensional grid of 44,45 mm (1,75 in) for chassis and the associated printed boards, which meets best the most frequent dimensional environment of the IEC 60297 series. Once this standard is est
49、ablished, the design and manufacturing of embedded computing solutions will gain significant cost efficiency.
