This blank detail specification determines the layout and style for detail specifications describing cords with transmission characteristics up to 100 MHz for digital communications. Det
29、ail specifications, based on this blank detail specification, may be prepared by a national organization, a manufacturer, or a user. Test configuration applicable to cords is detailed in the IEC 61935-2. The designation “Category 5e“ is used herein to describe an enhanced category 5 cable (see 1 of

The detail specifica
37、tion shall be written in accordance with the layout of the blank detail specification, which forms part of this standard. NOTE 1 When a characteristic does not apply, then “na” (for not applicable) should be entered in the appropriate space. NOTE 2 When a characteristic applies but a specific value
38、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 sectional specification should apply. The numbers shown in brackets in this and the following pages correspond to the following items of required
39、 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 number and date of issue. 3 Address of the organization from which the document is available. 4 Related documents. 5 Any other reference t
40、o the cable, national reference, trade name, etc. 6 A complete description of the cable which shall include a) type and number of elements; b) nominal impedance; c) screening; d) application; e) category; f) other distinguishing performance characteristics.

41、able for use in work area wiring, having a nominal impedance of 100 , and meeting the transmission requirements of category 5e 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.
42、 9 List of cable characteristics. They are separated into electrical, transmission, mechanical and environmental characteristics. The recommended environmental severities are derived from the MICE table requirements of EN 50173-3 . These recommendations were made to better reflect the cable behaviou
43、r. It should be noted that ingress requirements using particles are not applicable to a cable. The temperature requirements are addressed in 8. Rapid change of temperature is irrelevant for cables. _ 1The EN 50289-1-13 will be replaced with equivalent IEC publication when available. BS EN 61935-2-20
