It is thesecond edition of N
32、MX-J-534-ANCE, the second edition of CSA C22.2 No. 45.1, and the 14th edition ofUL 6. This edition of CSA C22.2 No. 45.1 supersedes the previous edition published in 2004. This editionof UL 6 supersedes the previous edition published June 30, 2004.This common standard was prepared by the Association
33、 of Standardization and Certification (ANCE),CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the conduit manufacturingindustry and the Technical Harmonization Subcommittee for Conduit and Tubing of the Council of theHarmonization of Electrotechnical Standards for the N
34、ations of the Americas (CANENA) are gratefullyacknowledged.This standard is considered suitable for use for conformity assessment within the stated scope of thestandard.The present Mexican standard was developed by CT Technical Committee 23 Electrical Accessories fromthe Comite de Normalizacion de l
35、a Asociacion de Normalizacion y Certificacion, A.C., CONANCE, with thecollaboration of the metal conduit and tubing manufacturers and users.This standard was reviewed by the CSA Subcommittee on Metal Conduit and Tubing, under thejurisdiction of the CSA Technical Committee on Wiring Products and the
36、CSA Strategic SteeringCommittee on Requirements for Electrical Safety, and has been formally approved by the CSA TechnicalCommittee.This standard has been approved by the American National Standards Institute as an American NationalStandard.Application of StandardWhere reference is made to a specifi
37、c number 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 thatit remains the responsibility of the users of the standard to judge its suitability for th
38、eir particular purpose.Level of harmonizationThis standard uses an IEC format, but is not based on, nor is it to be considered an IEC standard. Thisstandard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standardis a standard that is substantially the same in techn
39、ical content, except as follows: Technical nationaldifferences are allowed for codes and governmental regulations as well as those recognized as being inaccordance with NAFTA Article 905, for example, because of fundamental climatic, geographical,technological, or infrastructural factors, scientific
40、 justification, or the level of protection that the countryconsiders appropriate. Presentation is 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
41、 the scope of this standard. The IEC standards for electrical conduit andtubing are recognized as being generally system-specific, containing the requirements for the relevantconduits and cables and associated fittings in several discrete IEC standards.NOVEMBER 14, 2014NMX- J-534-ANCE-2007 CSA C22.2
42、 NO. 45.1-07 UL 64The THSC determined the safe use of electrical conduit 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
43、 lead to harmonizationof traditional North American electrical conduit and tubing and associated fittings with those presentlyaddressed in the known IEC standards. The THSC agreed such future investigation might be facilitatedby completion of harmonization of the North American standards for electri
44、cal conduit and tubing and theirfittings.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard shallbe based on the literal text to determine compliance with the standard in accordance with the proceduralrules of the standards development
45、organization. If more than one interpretation of the literal text has beenidentified, a revision shall 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
46、Diario Oficial de la Federacin (OfficialGazette) and is indicated on the cover page.CSA Group Effective DateThe effective date for CSA International will be announced through a CSA Informs or CSA GroupCertification Notice.UL Effective DateAs of November 14, 2014 all products Listed or Recognized by
47、UL must comply with the requirements inthis standard.A UL effective date is established by Underwriters Laboratories Inc. and is not part of the ANSI approvedstandard.NOVEMBER 14, 2014 NMX- J-534-ANCE-2007 CSA C22.2 NO. 45.1-07 UL 6 5Electrical Rigid Metal Conduit Steel1 Scope1.1 These requirements
48、cover electrical rigid metal conduit steel (ERMC-S), elbows, couplings, andnipples for use as a metal raceway for installation of wires and cables in accordance with CSA C22.1,Canadian Electrical Code, Part 1, NOM-001-SEDE, Standard for Electrical Installations, and NFPA 70,National Electrical Code
49、(see Reference Item No. 1, Annex A). ERMC-S is provided with a zinc,zinc-based, nonmetallic, or other alternate corrosion-resistant exterior coating and an organic or zincinterior coating. It is the users responsibility to determine the appropriate product for their application.1.2 Non-ferrous and stainless steel conduit are covered by the standards listed in Reference Item No. 2,Annex A.2 Normative references2.1 Products covered by this standard shall comply with the reference installation codes
