29、0-22 4 D1UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL PREFACE This is the common CSA and UL Standard for Information Technology Equipment Safety Part 22: Equipment to be Installed Outdoors. It is the rst edition of CAN/CSA-C22.2 No. 60950

30、-22 and the rst edition of UL 60950-22. This standard is based on IEC 60950-22, rst edition. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories Inc. (UL). The efforts and support of representatives of leading industry companies and organizatio

31、ns 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 Safety of Electronic Equipment within the Field of Audio/Video, Information, and Communication Technol

32、ogy, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial 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 Cana

33、da by the Standards Council of Canada. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Note: Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibi

34、lity of the users of the Standard to judge its suitability for their particular purpose. Level of harmonization This standard adopts the IEC text with national differences. This standard is published as an equivalent standard for CSA and UL. An equivalent standard is a standard that is substantially

35、 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 example, because of fundamental climatic, geographical, technological, or infrastructura

36、l factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. All national differences from the IEC text are included in the CSA and UL versions of the standard. While the technical content is the same

37、in each organizations version, the format and presentation may differ. Reasons for differences from IEC The national differences in this binational Part 22 Standard are included to reference the binational version of IEC 60950-1, which is designated as CAN/CSA-C22.2 No. 60950-1/UL 60950-1, to addres

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 accordance with

41、 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.

The national difference type is noted in the margin next to the affected text. The standard

44、may not include all types of these national differences. D1 national differences based on national regulatory requirements which result in equivalent or more stringent requirements than in IEC 60950-22. D2 national differences based on other than national regulatory requirements which result in equi
