35、cables. It is the eighth edition of CSAC22.2 No. 214 and the fifth edition of UL 444. This edition of CSA C22.2 No. 214 supersedes the previouseditions published in 2008, 2002, 1994, 1990, 1988, 1986, and 1984. This UL edition supersedes theprevious editions published in 2008, 2002, 1994 and 1990.Th
36、is common Standard was prepared by the Canadian Standards Association and UnderwritersLaboratories Inc. The efforts of the UL 444/CSA 214 Harmonization Committee are greatly appreciated.This Standard is considered suitable for use for conformity assessment within the stated scope of theStandard.This
37、 Standard was reviewed by CSA ICWC05-Control, Instrument, Communication, and Marine Cables, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.This
38、standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere reference is made to a specific number of samples to be tested, the specified number isconsidered a minimum quantity.Note: Although the intended primary applica
39、tion of this Standard is stated in its Scope, it is important to note that itremains the responsibility of the users of the standard to judge its suitability for their particular purpose.Level of HarmonizationThis standard uses an IEC format, but is not based on, nor is it to be considered equivalen
40、t to, an IECstandard. This standard is published as an identical standard. An identical standard is a standard that isthe same in technical content except for conflicts in codes and governmental regulations. Presentation isword for word except for editorial changes.InterpretationsThe interpretation
41、by the standards development organization of an identical or equivalent standard isbased on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization. If more than one interpretation of the literal text has beenidentif
42、ied, a revision is to be proposed as soon as possible to each of the standards developmentorganizations to more accurately reflect the intent.JANUARY 20, 2017 CSA C22.2 NO. 214-17 UL 444 5Communication Cables1 Scope1.1 This standard applies to 60 250C single- or multiple-conductor jacketed or unjack
43、eted, integral ornonintegral cables and single or multiple coaxial cables for telephone and other communication circuitssuch as voice, data, and audio for on-premise customer systems. These cables are may contain one ormore optical fibre members. For the purpose of this standard, a coaxial cable or
44、coaxial memberconductor is a single conductor with a shield. For the purpose of this standard, a single- ormultiple-conductor unjacketed cable is a cross-connect wire.1.2 This standard applies to communications cables that are intended primarily for installation inaccordance with Section 60 of the C
45、anadian Electrical Code Part I, and Article 800 of the NationalElectrical 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 whichthey are intended.1
46、.3 This standard does not apply to communications cords.1.4 In Canada, the Type -CI circuit integrity markings are not recognized by the Canadian ElectricalCode, Part I.In the US, Type CMH is not recognized in the NEC.1.5 If a value for measurement is followed by a value in other units in parenthesi
47、s, the second value maybe only approximate. The first stated value is the requirement.2 Reference publicationsAny undated reference to a code or standard appearing in the requirements of this standard shall beinterpreted as referring to the latest edition of that code or standard.CSA GroupC22.115Can
