22、 MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL PREFACE This is the harmonized ANCE, CSA Group, and UL standard for Sealed Twist-On Connecting Devices. It is the rst edition of NMX-J-745-ANCE, the rst edition of CSA C22.2 No. 355, and the rst edition of U

23、L 486G. This harmonized standard was prepared by the Association of Standardization and Certication, (ANCE), CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee, CANENA Technical Harmonization Committee 99 Electrical Connectors on the H

24、armonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. are gratefully appreciated. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Subcommit

25、tee on Wiring Devices for Household and General Use, under the jurisdiction of the CSA Technical Committee on Industrial 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 deve

26、loped in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application o

27、f 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 that it remains the responsibility of the users o

28、f the standard to judge its suitability for their particular purpose. Level of Harmonization This standard is published as an identical standard for ANCE, CSA Group, and UL. An identical standard is a standard that is exactly the same in technical content except for national differences resulting fr

29、om conicts in codes and governmental regulations. Presentation is word for word except for editorial changes. Interpretations 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

30、accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal 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.
