It is the thirdedition of NMX-J-536-ANCE, the

32、 second edition of CSA C22.2 No. 83.1, and the ninth edition of UL 797.This edition of CSA C22.2 No. 83.1 supersedes the previous edition published in 2004. This edition of UL797 supersedes the previous edition published June 30, 2004.This common standard was prepared by the Association of Standardi

33、zation and Certification (ANCE),CSA Group, and Underwriters Laboratories Inc. (UL), and the conduit manufacturing industry. The effortsand support of the Technical Harmonization Subcommittee for Conduit and Tubing, of the Council of theHarmonization of Electrotechnical Standards for the Nations of t

34、he Americas (CANENA) are gratefullyacknowledged.This standard is considered suitable for use for conformity assessment within the stated scope of thestandard.This standard was reviewed by the CSA Subcommittee on Metal Conduit and Tubing, under thejurisdiction of the CSA Technical Committee on Wiring

35、 Products and the CSA Strategic SteeringCommittee on Requirements for Electrical Safety, and has been formally approved by the TechnicalCommittee.This standard has been approved by the American National Standards Institute as an American NationalStandard.Where reference is made to a specific number

36、of samples to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remainsthe responsibility of the users of the standard to judge its suitability for their parti

37、cular purpose.Level of harmonizationThis standard uses an IEC format, but is not based on, nor is it to be considered equivalent to an IECstandard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. Anequivalent standard is a standard that is substantially the same in

38、technical content, except as follows:Technical deviations are allowed for codes and governmental regulations and those recognized as beingin accordance with NAFTA Article 905, for example, because of fundamental, climatic, geographical,technological or infrastructural factors, scientific justificati

39、on, or the level of protection that the countryconsiders appropriate. Presentation is to be word for word except for editorial changes.Reasons for differences from IECThe Technical Harmonization Subcommittee identified several IEC standards that address electricalconduit and tubing included in the s

40、cope of this standard. The IEC standards for electrical conduit andtubing are recognized as being generally system-specific, containing the requirements for the relevantconduits, tubing, and associated fittings in several discrete IEC standards.The THSC determined the safe use of electrical conduit

41、and tubing is dependent on the design andperformance of the conduit and tubing systems with which they are intended to be installed. Significantinvestigation is required to assess safety and system compatibility issues that may lead to harmonizationof traditional North American electrical conduit an

42、d tubing and associated fittings with those presentlyDECEMBER 21, 2012NMX-J-536-ANCE CSA C22.2 NO. 83.1-07 UL 7974addressed in the known IEC standards. The THSC agreed such future investigation might be facilitatedby completion of harmonization of the North American standards for electrical conduit

43、and tubing and theirfittings.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard is tobe based on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development organization

44、. If more than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each of the standards developmentorganizations to more accurately reflect the intent.ANCE effective dateThe effective date for ANCE will be announced through the Diario Ofici

45、al de la Federacin (OfficialGazette) and is indicated on the cover page.CSA Group effective dateThe effective date for CSA Group will be announced through CSA Informs or a CSA Group CertificationNotice.UL effective dateAs of December 21, 2012, all products Listed or Recognized by UL must comply with

46、 the requirements inthis standard except for Clauses 7.8, 7.9, and Annex F (Clause F.1 and Table F1) which are effective June21, 2014.A UL effective date is established by Underwriters Laboratories Inc. and is not part of the ANSI approvedstandard.DECEMBER 21, 2012 NMX-J-536-ANCE CSA C22.2 NO. 83.1-
