Description / Abstract:

This standard primarily defines minimum electrical performance and allowable conductor sizes, stranding, and shielding for premise wiring cables for voice and data applications. The material and mechanical characteristics for these cables are covered under UL 444/CSA C 22.2 No. 214 where applicable. Definitions and applicable test methods are included herein.

This standard covers Category 3, Category 5, and Category 5e, 100 ohm unshielded and shielded twisted pair, and 150 ohm shielded twisted pair cables for voice and/or data communication systems.

This standard also includes several appendices that were developed for U.S. Government reference.

Requirements for Category 4 cable were removed from this edition as this cable is no longer widely used.

The products covered in this Standard shall conform to the requirements of Part 68 of the FCC rules and regulations, as well as the applicable article(s) of the National Electrical Code and/or other national and local codes and safety standards.

The performance requirements contained in this document are for cables as manufactured. The installed cabling system will have different characteristics. The performance of the installed cabling is a function of its components (i.e. cable, connecting hardware, work area, equipment, and patch cords) and installation methods. Requirements for the performance of the installed cabling system are outside the scope of this document.
