8、NCE WITH ISO/IEC 11801 Part 2-25: Work area with M12 4 poles connectors Blank detail specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object
9、 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 to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications
10、 (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising
11、 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, a
12、s nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees i
13、n 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 way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Comm
14、ittees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not prov
15、ide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the lat
16、est edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whe

25、es connectors Blank detail specification 1 Scope This part of IEC 61935, which is a blank detail specification, describes work area cord with M12 4 poles d-code connectors, as used in the ISO/IEC 24702 and IEC 61918. According to the above cabling specifications, although these cords have only two p
26、airs, their transmission performances, when applicable, are at least category 5 compliant for which the requirements are given in ISO/IEC 11801:2002/AMD2:2010, Clause 13. This specification should be used in conjunction with IEC 61156-1, IEC 61156-6 and IEC 61076-2-101 type D. The blank detail speci
27、fication determines the layout and style for detail specifications describing cords with transmission characteristics up to 100 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
28、configuration applicable to cords is detailed in IEC 61935-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

34、teristics indicated in the relevant sectional specification for the referenced category number, e.g. 5 and the characteristic impedance. The detail specification shall be written in accordance with the layout of the blank detail specification, which forms part of this standard. When a characteristic
35、 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, the appropriate requirement in the sectio
36、nal 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 the document. 2 IEC document number, issue
37、 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 number of elements; b) nominal impedance;
38、c) screening; d) application; e) specific category of cord, cable and connectors; f) other distinguishing performance characteristics. EXEMPLE 2-pair, shielded twisted pair cable for use in work area wiring, having a nominal impedance of 100 , and meeting the transmission requirements of category 5
39、and the coupling attenuation requirements of type III. 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, mechanical and environmental characteristic
40、s. 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 cable. BS IEC 61935-2-25:2015IEC 61935
41、-2-25:2015 IEC 2015 7 The temperature requirements are addressed in 8. Rapid change of temperature is irrelevant for cables. Electromagnetic requirements coming from the MICE table of ISO/IEC 24702 have been dealt with by using the requirements that are given for transfer impedance, screening attenu
42、ation and 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 to this co
43、rd. The values shall meet the requirements of the relevant sectional specification IEC 61156-6 for 2 pairs cable up to 100 MHz. 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 Commen
