The New Safety Standard for ITE and AV Equipment: IEC62368-1

Posted on 10 Apr 2017

Background of IEC62368-1

The boundaries between information technology and audio/ video technology have become increasingly blurred. For example, “when is a 15” TFT device a TV and when is it a PC monitor?” or “is a smartphone a telephone, a PC or is it a MP3 player”.   Application of safety standards such as IEC 60065 and IEC 60950-1 has led to certain devices being tested twice and sometimes there are conflicting requirements between the two product standards.  There is therefore a need for a single safety standard to replace the two existing IEC 60065 (Audio and Video) and IEC 60950-1 (Information and Communication Technology) product safety standards.

IEC60601: understanding the changes from 2nd to 3rd edition

Posted on 10 Sep 2014
The general standard IEC 60601 is the accepted standard for medical equipment, especially for medical electrical equipment and general requirements for basic patient safety. The standard 60601 is a widely accepted benchmark series for medical electrical equipment and compliance with IEC60601 has become a de-facto requirement for the commercialization of electrical medical equipment in many countries
