25、IREMENTS FOR HOME AND BUILDING ELECTRONIC SYSTEMS FOREWORD 1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the developm
26、ent of International Standards. Their preparation is entrusted to technical committees; any ISO and IEC member body interested in the subject dealt with may participate in this preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC also participate
27、in this preparation. 2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requi
28、res approval by at least 75 % of the national bodies casting a vote. 3) The formal decisions or agreements of IEC and ISO 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 int
29、erested IEC and ISO member bodies. 4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC, ISO and ISO/IEC publications
30、is accurate, IEC or ISO cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and ISO/IEC publications transparently to the maximum extent poss
31、ible in their national and regional publications. Any divergence between any ISO/IEC publication and the corresponding national or regional publication should be clearly indicated in the latter. 6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible
32、 for any equipment declared to be in conformity with an ISO/IEC publication. 7) All users should ensure that they have the latest edition of this publication. 8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts and members of their
33、technical committees and IEC or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC publication or a
34、ny other IEC, ISO or ISO/IEC publications. 9) 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. 10) Attention is drawn to the possibility that some of the elements of this Int
35、ernational Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 14762 has been prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC joint technical committee 1: Informati
36、on technology. This International Standard cancels and replaces ISO/IEC TR 14762, published in 2001, and constitutes a technical revision. The main changes with respect to the Technical Report are the following: While the Technical Report lists reasons for harms and some possible counter measures th
37、is International Standard enhances the list of hazards and specifies specific measures to counter them. This International Standard applies to all physical media while additional aspects of wireless and powerline covered in ISO/IEC 24767 meanwhile are not repeated. Copyright International Organizati

39、 be used as a normative reference in a dedicated product standard for the safety of home and building electronic systems. It is not intended to be used as a stand-alone publication.

41、No reproduction or networking permitted without license from IHS -,-,- 6 FDIS 14762 ISO/IEC:2007(E) INTRODUCTION Home and Building Electronic System (HBES) products integrated in a HBES should be safe for the use in intended applications. This International Standard specifies the general functional
42、safety requirements for HBES following the principles of the basic standard for functional safety IEC 61508. This International Standard identifies functional safety issues related to products and their installation. The requirements are based on a risk analysis in accordance with IEC 61508. The int
43、ention of this International Standard is to allocate, as far as possible, all safety requirements for HBES products in there life cycle. This International Standard only addresses HBES products. This International Standard is addressed to committees that develop or modify HBES product/system standar
44、ds, or, where not suitable HBES product standards addressing functional safety exist, to product manufacturers. HBES and HES products in this International Standard are for non-safety related applications. Currently, ISO/IEC 14543, Information technology Home Electronic System (HES) architecture, co
