43、PRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized ANCE, CSA, and UL standard for Conduit, Tubing, and Cable Fittings. It is the Third edition of NMX-J-017-ANCE, the Second edition of CSA C22.2 No. 18.3, and the Sixth edition of UL 514B. This edition of CSA-C22.2 No

44、. 18.3 supersedes the previous edition(s) published in 2004. This edition of UL 514B supersedes the previous edition(s) published in 2004. This harmonized standard was prepared by the Association of Standardization and Certication (ANCE), the Canadian Standards Association (CSA), and Underwriters La

45、boratories Inc. (UL). The efforts and support of the Technical Harmonization Subcommittee, Conduit and Cable Fittings, 23A, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This standard is considered suitable for

46、 use for conformity assessment within the stated scope of the standard. This Standard was reviewed by the CSA Integrated Committee on Fittings, Hardware, and Positioning Devices, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requ

47、irements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Where reference is made to a specic number of samples to be tested, the specied number

48、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 that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This

49、standard uses the IEC format but is not based on, nor is it to be considered equivalent to, an IEC standard. This standard is published as an equivalent standard for ANCE, CSA, 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
