The existence of an IEEE standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is ap

In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or

In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard.
12、Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal
13、position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE. Comments on standards Commen
14、ts for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a p
15、roposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its
16、societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate i
17、n revisions to an IEEE standard is welcome to join the relevant IEEE working group. Comments on standards should be submitted to the following address: Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USA Laws and regulations Users of IEEE Standards documents should consult all
18、applicable laws and regulations. Compliance with the provisions of any IEEE Standards document does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the
19、 publication of its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so. Copyrights IEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws. They are made available by IEEE
20、 and are adopted for a wide variety of both public and private uses. These include both use, by reference, in laws and regulations, and use in private self-regulation, standardization, and the promotion of engineering practices and methods. By making these documents available for use and adoption by
21、 public authorities and private users, IEEE does not waive any rights in copyright to the documents. Photocopies Subject to payment of the appropriate fee, IEEE will grant users a limited, non-exclusive license to photocopy portions of any individual standard for company or organizational internal u
22、se or individual, non-commercial use only. To arrange for payment of licensing fees, please contact Copyright Clearance Center, Customer Service, 222 Rosewood Drive, Danvers, MA 01923 USA; +1 978 750 8400. Permission to photocopy portions of any individual standard for educational classroom use can
23、also be obtained through the Copyright Clearance Center. Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, c
24、orrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and
25、 has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard. In order to determine whether a g
26、iven document is the current edition and whether it has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/xpl/standards.jsp or contact IEEE at the address listed previously.

Users are encouraged to check this URL for errata perio

By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection ther
29、ewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing or
30、unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination to applicants desiring to obtain such licenses. Essential Patent Claims may exist for which a Letter of Assuran
31、ce has not been received. The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with submiss
32、ion of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further

All rights reserved. viii Introduction This introduction is not part of IEEE Std 1478-2013, IEEE Standard for Environmental Conditions for Transit Railcar Electronic Equipment. This standard establishes environmental conditions under which transit railcar electronic equi
41、pment shall both operate and/or survive, but not the conditions to be considered for the calculation for reliability. Environmental conditions specified include: temperature, humidity, vibration, mechanical shock, corrosives and abrasives, precipitation, flooding, ultraviolet radiation, and altitude
42、. This standard does not cover electromagnetic interference (EMI) or radio frequency interference (RFI). Environmental conditions depend upon equipment location such as vehicle exterioraxle mounted, truck sprung and body mounted and vehicle interiornon-conditioned and conditioned. This standard is i
43、ntended to cover the application of electronic equipment. It may be applied with consideration to electrical equipment and subsystems. Copyright 2013 IEEE. All rights reserved. ix Contents 1.
