It is submitted to the Unique Acceptance Procedure. This European Standard will supersede EN 41003:1998. The following dates are proposed: latest date by which the existence of the EN has to be announced at national level (doa) dor + 6 months latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) dor + 12 months latest date by which the national standards conflicting with the EN have to be withdrawn (dow) dor + 36 months (to be confirmed or modified when voting) The first edition of this European Standard was prepared by CENELEC TC 74X, in close cooperation with a number of international organizations, e.g. IEC, ECMA, CEPT, CCITT, ETSI. In 1993 TC 74X was disbanded and responsibility for this European Standard passed to the Technical Committee CENELEC TC 74, Safety and energy efficiency of information technology equipment. CENELEC TC 74 was disbanded by D112/112 in 2002 and merged with CENELEC TC 92 into new CENELEC TC 108, which was renumbered CENELEC TC 108X by 130 BT. At that time, a standard was needed for uniform application by network operators in Europe when approving subscribers' equipment for attachment to their networks, and for purchasing purposes by network operators. In February 1986 the CENELEC Technical Board formed a working group 'Telecom Safety' which became CENELEC/TC 74X in early 1987. IEC TC 74 established WG7 to amend IEC 60950 for a similar purpose. ENV 41003 was ratified by the CENELEC Technical Board in March 1988 and subsequently amended and converted into this EN 41003 which was ratified in September 1990. In June 1992 the CENELEC Technical Board approved the reprint of EN 41003, which was technically unchanged from EN 41003:1991 and refers to EN 60950:1992 wherever possible. The edition of EN 41003:1996 was deemed necessary following the publication of EN 60950:1992/A3:1995 to reflect further convergence of the two standards. The edition of EN 41003:1998 was deemed necessary following the publication of EN 60950:1992/A4:1997, to reflect further convergence of the two standards. This edition of EN 41003 was deemed necessary following the publication of EN 60950-1:2006 Information technology equipment Safety Part 1: General requirements (IEC 60950-1:2005, modified), to reflect further convergence of the two standards. _ Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 02:51:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSI Draft for vote 3 prEN 41003:2007 Contents Introduction 4 1 Scope. 5 2 Normative references 5 3 Definitions . 6 4 Safety requirements and compliance criteria 6 4.1 Interconnection of equipment General requirements. 6 4.2 TNV circuits. 6 4.3 Protection against contact with TNV circuits. 7 4.4 Protection of telecommunication network and/or cable distribution network service persons, and users of other equipment connected to the network, from hazards in the equipment 7 4.5 Protection of equipment users from overvoltages on telecommunication networks and/or cable distribution systems 7 4.6 Protection of the telecommunication wiring system from overheating. 7 Annex A (informative) Relevant safety standards for the application of this European Standard 8 Annex B (informative) Telecommunication network voltages and signals. 9 Bibliography11 Figure Figure B.1 Current limit curves .16 Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 02:51:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSI Draft for vote prEN 41003:2007 4 Introduction This European Standard is needed for products intended to be connected to a telecommunication network and/or a cable distribution system not covered by the scope of EN 60950-1. It is to be used in conjunction with other product safety standards; examples of which are listed in Annex A. Upper levels for telecommunication/cable distribution system signals have been defined. They include also telephone ringing signals which have been defined taking into account voltages commonly used in the different networks. The electrical hazard criteria have been chosen to accord with the IEC TS 60479 series. Test levels used for the equipment take account of the possibility that overvoltages may occur on telecommunication and cable distribution networks. Special consideration has been given to equipment parts expected to be held or touched during normal use, e.g. telephone handsets. It is recognised that in high overvoltages risk areas, requirements of this European Standard may not be sufficient; additional protective devices, not covered by this European Standard, may be installed in the communication networks to better meet extreme conditions. For the adoption of this European Standard, the relevant special national conditions and A-deviations apply that are listed in Annexes ZB and ZC of EN 60950-1. Licensed Copy: London South Bank University, London South Bank University, Thu Dec 20 02:51:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSI Draft for vote 5 prEN 41003:2007 1 Scope This European Standard applies to equipment designed and intended to be connected as a terminal to a TELECOMMUNICATIONS NETWORK and/or a CABLE DISTRIBUTION SYSTEM termination. It does not apply to equipment covered by EN 60950-1. This European Standard specifies the safety requirements of the interface to the telecommunication network and/or the cable distributions system only and it does not specify any other safety requirements. It applies regardless of ownership or responsibility for installation or maintenance of the equipment, and regardless of the source of power. This European Standard, in accordance with the 'principles of safety' given in the introduction of EN 60950-1, covers the requirements and compliance criteria under three headings. Protection of equipment users from hazards in the equipment. The user is considered to be protected from hazards in the equipment if the equipment complies with a relevant safety standard, for example one of those listed in Annex A, but compliance with those standards is not part of this European Standard. Protection of SERVICE PERSONNEL working on a TELECOMMUNICATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM and other users of a TELECOMMUNICATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM, from hazardous conditions on a TELECOMMUNICATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM resulting from the connection of the equipment. Protection of equipment users from voltages on a TELECOMMUNICATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM. Requirements additional to those specified in this European Standard may be necessary for equipment intended for operation while exposed, for example, to extremes of temperature, to excessive dust, moisture, or vibration, to flammable gases, to corrosive or explosive atmospheres, electromedical applications with physical connections to the patient. The requirements for the following items are not covered by this European Standard: functional reliability of equipment; communication facilities with remote supply using hazardous voltage; protection of equipment, TELECOMMUNICATION NETWORKS and/or CABLE DISTRIBUTION SYSTEMS from damage. 2 Normative references The following referenced documents are indisp
