24、 standard for electrical rigid metal conduit steel. It is the second edition of NMX-J-534-ANCE, the second edition of CSA C22.2 No. 45.1, and the 14th edition of UL 6. This edition of CSA C22.2 No. 45.1 supersedes the previous edition published in 2004. This edition of UL 6 supersedes the previous e

25、dition published June 30, 2004. This common standard was prepared by the Association of Standardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the conduit manufacturing industry and the Technical Harmonization Subcommittee for Conduit a

26、nd Tubing of the Council of the Harmonization of Electrotechnical Standards for the Nations of the Americas (CANENA) are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. The present Mexican standard was developed

27、 by CT Technical Committee 23 Electrical Accessories from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with the collaboration of the metal conduit and tubing manufacturers and users. This standard was reviewed by the CSA Subcommittee on Metal Conduit an

28、d Tubing, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the American National Standards Institu

29、te as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its scope, it is important to note

30、 that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard uses an IEC format, but is not based on, nor is it to be considered an IEC standard. This standard is published as an equivalent standard for A

31、NCE, CSA Group, and UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for exampl

32、e, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. Reasons for differences from IEC The Technical Harmonizati

33、on Subcommittee identied several IEC standards that address electrical conduit and tubing included in the scope of this standard. The IEC standards for electrical conduit and tubing are recognized as being generally system-specic, containing the requirements for the relevant conduits and cables and

34、associated ttings in several discrete IEC standards. NOVEMBER 14, 2014 NMX- J-534-ANCE-2007 CSA C22.2 NO. 45.1-07 UL 6 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL The THSC determined the safe use of electrical conduit and tubing is depe

35、ndent on the design and performance of the conduit and tubing systems with which they are intended to be installed. Signicant investigation is required to assess safety and system compatibility issues that may lead to harmonization of traditional North American electrical conduit and tubing and asso

36、ciated ttings with those presently addressed in the known IEC standards. The THSC agreed such future investigation might be facilitated by completion of harmonization of the North American standards for electrical conduit and tubing and their ttings. Interpretations The interpretation by the standar

37、ds development organization of an identical or equivalent standard shall be based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a

38、revision shall be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent. ANCE Effective Date The effective date for ANCE will be announced through the Diario Ocial de la Federacin (Official Gazette) and is indicated on the cover page. CSA

39、 Group Effective Date The effective date for CSA International will be announced through a CSA Informs or CSA Group Certication Notice. UL Effective Date As of November 14, 2014 all products Listed or Recognized by UL must comply with the requirements in this standard. A UL effective date is establi

40、shed by Underwriters Laboratories Inc. and is not part of the ANSI approved standard.

41、cope 1.1 These requirements cover electrical rigid metal conduit steel (ERMC-S), elbows, couplings, and nipples 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 NFP

42、A 70, National Electrical Code (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 zinc interior coating. It is the users responsibility to determine the appropriate product for their

43、application. 1.2 Non-ferrous and stainless steel conduit are covered by the standards listed in Reference Item No. 2, Annex A. 2 Normative references 2.1 Products covered by this standard shall comply with the reference installation codes and standards as appropriate for the country where the produc

44、t is to be used. When the product is intended for use in more than one country, the product shall comply with the installation codes and standards for all countries where it is intended to be used. A Reference Item No. is provided at the point of use for each reference in this standard. See Annex A

45、for a list of reference publications and the correlating list of reference item numbers to applicable country publications. 2.2 For undated references to standards, such reference shall be considered to refer to the latest edition and all revisions to that edition up to the time when this standard w

46、as approved. For dated references to standards, such reference shall be considered to refer to the dated edition and all revisions published to that edition up to the time the standard was approved. 3 Denitions 3.1 The following denitions apply in this standard. 3.2 Bare threaded tube. A standard le

47、ngth of threaded tube intended to be coated with an alternate corrosion-resistant coating and having a separate coupling. 3.3 Coating(s), alternate corrosion-resistant.

48、vel of corrosion resistance required on the exterior of conduit. See Clause 6.2.4. Note: The coating(s) may include zinc. 3.4 Coating(s), organic. An interior coating(s), other than one consisting solely of zinc, which, upon evaluation, has demonstrated the ability to provide the level of corrosion

49、resistance necessary where the coating is not subject to physical damage. See Clause 6.2.3. Note: The coating(s) may include zinc. 3.5 Coating(s), zinc. A primary coating consisting solely of zinc, which upon evaluation has demonstrated the ability to provide the level of corrosion resistance required on the exterior or interior of conduit as applicable.
