UL LLC also announced recently the publication of our Certification Impact Analysis on this new edition. This latest analysis is intended to identify and analyze the impact of notable differences between the latest Edition No. 3 of IEC 62368-1:2018, Audio/Video, Information and Communication Technology Equipment – Part 1: Safety Requirements, and its immediate predecessor, IEC 62368-1:2014 (Ed. No. 2).  

 

This analysis will permit persons already familiar with Ed. No. 2 of IEC 62368-1 to become familiar with the likely impact of the latest edition on safety of AV & ICT Equipment. Other select observations are included that may be of interest to the reader. This analysis will be updated periodically as additional information on the application of the new Standard becomes known.
