9、TERNATIONAL ELECTROTECHNICAL COMMISSION _ GENERIC CABLING SYSTEMS SPECIFICATION FOR THE TESTING OF BALANCED COMMUNICATION CABLING IN ACCORDANCE WITH ISO/IEC 11801 Part 2-23: Cord and work area cord category 7 Blank detail specification FOREWORD 1) The International Electrotechnical Commission (IEC)

10、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 standardization in the electrical and electronic fields. To this end and in addition t

11、o 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 entrusted to technical committees; any IEC National Committee interested in

12、 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 International Organization for Standardization (ISO) in accordance with condi

13、tions 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 since each technical committee has representation from all interested IEC Nati

14、onal 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 of IEC Publications is accurate, IEC cannot be held responsible for the wa

15、y 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 in their national and regional publications. Any divergence between any IEC

16、 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 assessment services and, in some areas, access to IEC marks of conformity. I

17、EC 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, employees, servants or agents including individual experts and members of it

18、s 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 the publication, use of, or reliance upon, this IEC Publication or any oth

19、er 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 the possibility that some of the elements of this IEC Publication may be the

20、 subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61935-2-23 has been prepared by IEC technical committee 46: Cables, wires, waveguides, R.F. connectors, R.F. and microwave passive components and accessories. The te

21、xt of this standard is based on the following documents: FDIS Report on voting 46/556/FDIS 46/562/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

26、 IN ACCORDANCE WITH ISO/IEC 11801 Part 2-23: Cord and work area cord category 7 Blank detail specification 1 Scope This part of IEC 61935, which is a blank detail specification, describes cords and work area cords category 7, as defined in ISO/IEC 11801 series. According to the above cabling specifi

27、cations, these cords are category 7 compliant for which the requirements are given in ISO/IEC 11801 series. This specification should be used in conjunction with IEC 61935-2, IEC 61156-1 and IEC 61156-6 and IEC 60603-7-7. The blank detail specification determines the layout and style for detail spec

28、ifications describing cords with transmission characteristics up to 600 MHz for digital communications. Detail specifications, based on the blank detail specification, may be prepared by a national organization, a manufacturer, or a user. Test configuration applicable to cords is detailed in IEC 619

29、35-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

35、ecessary to keep the transmission characteristics indicated in the relevant sectional specification for the referenced category number, i.e. 7 and the characteristic impedance. The detail specification shall be written in accordance with the layout of the blank detail specification, which forms part

36、 of this standard. When a characteristic does not apply, then na (for not applicable) should be entered in the appropriate space. When a characteristic applies but a specific value is not considered necessary, then ns (for not specified) should be entered in the appropriate space. When ns is used, t

37、he appropriate requirement in the sectional specification should apply. The numbers shown in brackets in this and the following pages correspond to the following items of required information, which should be entered in the spaces provided. 1 Name and address of the organization that has prepared th

38、e document. 2 IEC document number, issue number and date of issue. 3 Address of the organization from which the document is available. 4 Related documents. 5 Any other reference to the cable, national reference, trade name, etc. 6 A complete description of the cord which shall include a) type and nu

39、mber of elements; b) nominal impedance; c) screening; d) application; e) Specific category of cord, cable and connectors; f) other distinguishing performance characteristics. EXEMPLE 4-pair, shielded twisted pair cable for use in work area wiring, having a nominal impedance of 100 , and meeting the

40、transmission requirements of category 7 and the coupling attenuation requirements of type I. 7 Details of the cable material and construction. 8 Special requirements for bending radius or operating temperatures. 9 List of cable characteristics. They are separated into electrical, transmission, mecha

41、nical and environmental characteristics. The recommended environmental severities are derived from the MICE table requirements of ISO/IEC 24702. These recommendations were made to better reflect the cable behaviour. It should be noted that ingress requirements using particles is not applicable to a

42、cable. The temperature requirements are addressed in 8. Rapid change of temperature is irrelevant for cables. BS IEC 61935-2-23:2015IEC 61935-2-23:2015 IEC 2015 7 Electromagnetic requirements coming from the MICE table of ISO/IEC 24702 have been dealt with by using the requirements that are given fo

43、r transfer impedance, coupling attenuation. ESD requirements are considered non-applicable. 10 Appropriate subclause references in the generic specification IEC 61156-1/IEC 61935-2. 11 Appropriate subclause references in the sectional specification IEC 61156-6/IEC 61935-2. 12 Requirements applicable

44、 to this cord. The values shall meet the requirements of sectional specification IEC 61156-6 for category 7. For those limits that are not related to the cord category and for which a choice is proposed, they have to be chosen to meet the related MICE table requirements. 13 Comments Relevant remarks
