15、 Manufacturers Association iii Foreword This standard publication sponsored and published by ICEA and approved by NEMA on cables to be used for voice, data, video, and other high-frequency signal transmission. This standards publication is published in the public interest and is intended to promote
16、product uniformity and quality throughout the industry. Existence of this publication does not in any respect preclude the manufacture or use of products not conforming to the Standard. Compliance with this standard may require use of an invention covered by patent rights. By publication of this doc
17、ument, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a license under these rights on reasonable and non-discriminatory terms and conditions to applicants desir
18、ing to obtain such a license. Details may be obtained from the publisher. The user of this standard is cautioned to observe any applicable health or safety regulations and rules relative to the manufacture and use of cable made in conformity with this standard. This standard hereafter assumes that m
19、anufacture, testing, installation, and maintenance of cables defined by this standard will be performed only by properly trained personnel using suitable equipment and employing appropriate safety precautions. This standards publication has been jointly developed by the Communications Division (memb
20、ers as listed below) of the Insulated Cable Engineers Association and the Premise Wiring Subcommittee (members as listed below) of the High Performance Wire and Cable Section of NEMA in close coordination between manufacturers, users, third party certifying agencies, and others having specialized ex

43、ION OF CABLE TYPES: Horizontal cables are normally used in that portion of the telecommunications cabling system between the telecommunications closet and the work area telecommunications outlet. The conductors are solid. Backbone cables are normally used in that portion of the telecommunications ca
44、bling system between telecommunications closets, equipment rooms, and entrance facilities within a building. The conductors are solid. Patch cordage is a length of cable used in the manufacture of patch cords where it is combined with connectors on one or both ends to join telecommunication circuits
45、/links at the cross-connect and to connect workstations to the wall outlet. The conductors may be solid or stranded. 1.6 OPTIONS AND INFORMATION: This standard is arranged in sections covering specific areas of cable requirements and may be referenced as complete Sections or as individual paragraphs
46、. Paragraphs of this Standard where the user may specify a particular option are listed below: 2.1 Solid Conductors for Horizontal and Backbone Cables, and Patch Cordage 2.2 Stranded Conductors for Patch Cordage 3.1.1 Heavy Metal Free Insulation 3.1.2 Low Halogen Insulation Material 3.4.3 Color Code

48、ngs between the manufacturer and user, it is suggested that a check-off sheet similar to that shown in Informative Annex A be utilized. 1.7 UNITS AND TOLERANCES: SI units (see NIST-SP 811) are specified throughout this Standard except for conductor size. Approximate US equivalents and Fahrenheit tem
49、peratures are provided for information only. The rounding-off method of ASTM E 29 shall be used for determining conformance with requirements.
