CERTIFICATION IMPACT ANALYSIS: (UL) IEC 60950-1, …

1 : January 16, 2015. Page 1 of 23. CERTIFICATION IMPACT ANALYSIS: (UL) IEC 60950 -1, EDITION No. 2, AMENDMENT No. 2. Safety of Information Technology Equipment Technical Editor: Thomas M. Burke Principal Engineer ICT, Consumer Technology Division UL LLC. This analysis is intended to identify and analyze the IMPACT of notable differences between the latest versions of the IEC and UL standards for Safety of Information Technology Equipment (ITE) and their predecessors. In particular, the Second Amendment to IEC.

2 60950 -1 Second Edition is being analyzed and compared to its predecessors, mainly IEC. 60950 -1 Second Edition, Amendment No. 1 and UL 60950 -1 Second Edition. Amendment No. 2 to IEC 60950 -1 Second Edition was published in May 2013. The corresponding revisions to CSA No. 60950 -1/UL 60950 -1, Second Edition, were published on October 14, 2014, and this Analysis also includes analysis of any changes to the National Differences associated with the latest bi-national standard. This Analysis also will make note of any new Common and Special National Conditions associated with EN 60950 -1:2006/A1:2010/A2:2013 (August 2014) that are considered noteworthy due to potential IMPACT on global products.

3 (To date, non-have been identified specifically associated with A2.). This analysis will permit persons already familiar with IEC 60950 -1 and UL 60950 -1 to become familiar with the likely IMPACT on ITE of the latest IEC and UL ITE Safety Standards. Other select observations are included that may be of interest to the reader. This analysis will be updated as additional information on the application of the new Standards becomes known. One key thing to keep in mind is that IEC TC108 has made a commitment to limit further revision of IEC 60950 -1 and concentrate its work and effort on IEC 62368-1, Audio/video, information and communication technology equipment Part 1: Safety requirements, the Standard that eventually will replace IEC 60065 (AV Equipment).

4 And IEC 60950 -1 (ICT Equipment). (Edition No. 2 of IEC 62368-1 was published in February 2014.) Therefore, most of these changes in Amendment No. 2 were adopted to allow for continued effective application of IEC 60950 -1 during the transition. Background IEC 60950 -1 is the International Standard for Safety of Information Technology Equipment. It encompasses under its scope information technology equipment, communication technology equipment, office appliances and multi-media equipment for use in the home, office, business, school, computer room and similar locations.

IEC TC 108 also is responsible for, IEC 60950 -21, Information technology equipment Safety Part 21: Remote power feeding;. IEC 60950 -22, Safety of Information Technology Equipment Part 22: Equipment Installed Outdoors;. IEC 60950 -23, Safety of Information Technology Equipment Part 23: Large Data Storage Equipment.

6 IEC 60990, Methods of Measurement of Touch Current and Protective Conductor Current;. IEC 62151, Safety of Equipment Electrically Connected to a Telecommunication Network;. IEC/TR 62102, Electrical Safety - Classification of Interfaces for Equipment to be Connected to Information Technology and Communications Technology Networks; and IEC/TS 62367 Safety aspects for xDSL signals on circuits connected to telecommunication networks. In the and Canada, the current ITE Bi-National Standard (BNS), formally designated CSA No.

7 60950 -1/UL 60950 -1, Second Edition, is based on the Second Edition of IEC. 60950 -1, including Amendment Nos. 1 and 2. Like its predecessors includes deviations (National Differences) to address needed national requirements that are not in the base IEC document. The technical content of the BNS is developed and maintained by the Technical Harmonization Committee (THC), Maintenance Team No. 2 (MT2), which consists of representation from UL, CSA, and several and Canadian IT and communication technology equipment industry groups.

8 The Effective Date for UL 60950 -1 Second Edition is outlined on the UL website - Notes to this Analysis: Unless otherwise noted, all Sub-clause/Annex references are to the Amendment No. 2 of IEC 60950 -1, Edition No. 2. Discussion of changes and differences associated with Amendment No. 2 to IEC 60950 - 1, Second Edition is in plain text. Discussion of new or revised national differences specifically associated with October 14, 2014 revisions of the Bi-National Standard, CSA No. 60950 -1/UL 60950 -1, Second Edition are noted, ND.

9 Discussion of new or revised special national conditions (differences) associated with CENELEC EN 60950 -1:2006/A1:2010/A2:2013 are noted, CENELEC ND. Explanation of IMPACT Statements: Statement IMPACT None Anticipate no IMPACT on the present CERTIFICATION practice of most ITE due to the change. Minor* Anticipate limited IMPACT on the present CERTIFICATION practice of some, or all ITE due to the change. Considerable* Anticipate considerable IMPACT on the present CERTIFICATION practice of some, or all ITE due to the change.

For new/revised requirements that are considered at this time less onerous than existing requirements, the IMPACT Statement (Minor, Considerable) will be followed by a (-). No symbol next to a Minor statement indicates that, although there could be limited IMPACT associated with the change, it is indeterminate whether it will be slightly more or less.
