16、3:1998 BSI 05-1999 Foreword The first edition of this 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 standard passed to CENELEC TC 74. In September
17、 1985, IEC published its Guide 105, produced jointly with CCITT, for use by technical committees responsible for equipment safety standards who wished to enhance their specific standards by adding harmonized requirements for telecommunication safety. Guide 105 is concerned with safety aspects which
18、arise when equipment is connected to a telecommunication network. However, it is not written as a standard for testing and approval purposes. At that time, a standard was needed for uniform application by network operators in Europe when approving subscribers equipment for attachment to their networ
19、ks, 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 Boar
20、d in March 1988 and subsequently amended and converted it 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
21、of EN 41003:1996 was deemed necessary following the publication of EN 60950:1992/A3:1995, to reflect further convergence of the two standards. This edition of EN 41003 was deemed necessary following the publication of EN 60950:1992/A4:1997, to reflect further convergence of the two standards. This n
22、ew edition was ratified by the CENELEC Technical Board on 1998-08-01. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 1999-06-01 latest date by which the national standards co

29、n This standard follows and extends the principles of IEC Guide 105 and reconciles the safety requirements set by the IEC for the use of electrical products with the considerable safety experience of telecommunication network operators in the operation of their networks. The standard recognises that
30、 although telecommunication networks have been shown to be safe to the touch in normal operation, some particular requirements should nevertheless be applied when equipment connected to these networks is used in subscribers premises. These requirements ensure that possible hazards from equipment wil
31、l not be propagated to the network. They also ensure that no contact can be made to network voltages through the equipment itself, and that at connection sockets where some access must be available, inadvertent contact or any contact with a large area of skin is prevented. Upper levels for telecommu
32、nication 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 IEC 60479-1. Test levels used for the equipment take account of
33、 the possibility that overvoltages may occur on the telecommunication network. 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 overvoltage risk areas, requirements of this standard may no
34、t be sufficient; additional protective devices, not covered by this standard, may be installed in the telecommunication network to better meet extreme conditions. For the adoption of this standard, the relevant special national conditions and A-deviations apply that are listed in annexes ZB and ZC o
35、f EN 60950:1992, including amendments. 1 Scope This standard applies to equipment designed and intended to be connected to a TELECOMMUNICATIONS NETWORKtermination. It does not apply to equipment covered by EN 60950. It applies regardless of ownership or responsibility for installation or maintenance
36、 of the equipment, and regardless of the source of power. This standard, in accordance with the principles of safety given in the introduction of EN 60950, covers the requirements and compliance criteria under three headings: protection of equipment users from hazards in the equipment. The user is c
37、onsidered 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 standard; protection ofSERVICE PERSONNELworking on the TELECOMMUNICATION NETWORKand o
38、ther users of theTELECOMMUNICATION NETWORK, from hazardous conditions on theTELECOMMUNICATION NETWORK resulting from the connection of the equipment; protection of equipment users from voltages on theTELECOMMUNICATION NETWORK. Requirements additional to those specified in this standard may be necess
39、ary 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 follo
40、wing items are not covered by this standard: functional reliability of equipment; telecommunication facilities with remote supply usingHAZARDOUS VOLTAGE; protection of equipment or TELECOMMUNICATION NETWORKSfrom damage. 2 Normative references This European Standard incorporates by dated or undated r
41、eference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incor
42、porated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
