44、 the work area telecommunications outlet. The conductors are solid. Backbone cables are normally used in that portion of the telecommunications cabling system between telecommunications closets, equipment rooms, and entrance facilities within a building. The conductors are solid. Patch cordage is a
45、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/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 sta
46、ndard is arranged in sections covering specific areas of cable requirements and may be referenced as complete Sections or as individual paragraphs. Paragraphs of this Standard where the user may specify a particular option are listed below: 2.1 Solid Conductors for Horizontal and Backbone Cables, an
47、d 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 for Patch Cordage 4.3 Ripcord 5.1 Shielding System 6.1.1 Heavy Metal Free Jacket 6.1.2 Low Halogen Jacket Material 6.4 Jacket Color 8.5 Flammability 8.6
48、Limited Smoke 8.7 Halogen Content 9.3 Length Marking 9.5 Packaging To assist the user in selection of options and to avoid possible misunderstandings 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 TOLE
49、RANCES: SI units (see NIST-SP 811) are specified throughout this Standard except for conductor size. Approximate US equivalents and Fahrenheit temperatures are provided for information only. The rounding-off method of ASTM E 29 shall be used for determining conformance with requirements. ANSI/NEMA WC 66/ICEA S-116-732-2013 2014 National Electrical Manufacturers Association 7 1.8 QUALITY ASSURANCE: It is the responsibility of the manufacturer to establish a quality assurance system consistent with ANSI/ASQC Q9000-1, Q9004-1, TL-9
