It is the fourth editi

25、on of CSA C22.2 No. 227.1 and the second edition of UL 1653. This edition of CSA C22.2 No. 227.1 supersedes the previous edition published in 1997. This edition of UL 1653 supersedes the previous edition published in 1997. This harmonized standard has been jointly revised on December 23, 2014. For t

26、his purpose, CSA Group and UL are issuing revision pages dated December 23, 2014. This harmonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee 23A ENT Working Group of the Council on the Harmonization

27、 of Electrotechnical Standards of 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. This standard was reviewed by the CSA Subcommittee on Nonmetallic Conduit, Tubing, and F

28、ittings, 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 as a National Standard of Canada by the Sta

29、ndards Council of Canada (SCC). This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number shall be considered a minimum quantity.

30、 Note: Although the intended primary application of this standard is stated in its scope, it is important to note 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 the IEC format but is not

31、 based on, nor shall it be considered equivalent to, an IEC standard. This standard is published as an equivalent standard for 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

32、 codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriat

33、e. Presentation is word for word except for editorial changes. Reasons for differences from IEC The Technical Harmonization Committee determined the safe use of electrical nonmetallic tubing and ttings is dependent on the design and performance of the raceway and cable systems with which they are in

34、tended to be installed. Signicant investigation is required to assess safety and system compatibility issues that may lead to harmonization of traditional North American nonmetallic tubing and ttings with DECEMBER 23, 2014 CSA C22.2 NO. 227.1-06 UL 1653 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FU

35、RTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL those presently addressed in the known IEC standards. The THC agreed such future investigation might be facilitated by completion of harmonization of the North American standards for electrical nonmetallic tubing and ttings. Interpretatio

36、ns The interpretation by the standards development organization of an identical or equivalent standard is 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 lite

37、ral text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent. CSA Group Effective Date The effective date for CSA Group will be announced through a CSA Informs or CSA Group Certication Notice. UL E

38、ffective Date As of December 23, 2014 all products Listed or Recognized by UL must comply with the requirements in this standard.

40、ectrical Code, Part I (CEC), and NFPA 70, National Electrical Code (NEC). These requirements also apply to mechanically-attached ttings integral with an outlet box. 1.2 Products covered by this Standard are intended for use: a) at a maximum continuous operating temperature of 75C (167F); b) at a max

41、imum ambient temperature of 50C (122F); c) in attics provided that the ENT is installed no higher than 900 mm (3 ft) above the bottom of the ceiling joist, and the ENT material is rated minimum 60C (140F); and d) underground (direct burial), in Canada only. 1.3 This Standard does not apply to ttings

42、 that are intended to be joined by solvent cement. Solvent-attached ttings are covered by UL 651 or CSA C22.2 No. 211.2. Solvent-attached ttings integral with an outlet or ush device box are covered by UL 514C or CAN/CSA-C22.2 No. 85. 2 Denitions 2.1 The following denitions apply to this Standard: A

43、dapter a tting used to terminate the ENT at an electrical enclosure. Coupling a tting intended to connect two lengths of ENT. Coupling, Split-Type a two-piece coupling normally used to connect two lengths of ENT after conductors have been pulled. Electrical Nonmetallic Tubing (ENT) a pliable corruga

44、ted raceway of circular cross-section, capable of being bent by hand with a reasonable force, but without other assistance. Fitting, Mechanically Attached a component in the ENT system used to terminate a length of ENT and secured to the ENT by means other than solvent cement. Fitting, Solvent-Attac
