This standard applies to 60 ?C 250??single- or multiple-conductor jacketed or unjacketed@ integral or nonintegral cables and single or multiple coaxial cables for telephone and other communication circuits such as voice@ data@ and audio for on-premise customer systems. These cables are may contain one or more optical fibre members. For the purpose of this standard@ a coaxial cable or coaxial member conductor is a single conductor with a shield. For the purpose of this standard@ a single- or multiple-conductor unjacketed cable is a cross-connect wire. This standard applies to communications cables that are intended primarily for installation in accordance with Section 60 of the Canadian Electrical Code Part I@ and Article 800 of the National Electrical Code (NEC)@ ANSI/NFPA 70. They are rated for 300 V applications@ but are not so marked. Note: See Annex A for a complete list of wire types covered by this Standard and the specific electrical codes for which they are intended. This standard does not apply to communications cords. In Canada@ the Type ??I??ircuit integrity markings are not recognized by the Canadian Electrical Code@ Part I. In the US@ Type CMH is not recognized in the NEC. If a value for measurement is followed by a value in other units in parenthesis@ the second value may be only approximate. The first stated value is the requirement.
