A Shift to Hazard Based Safety Engineering


IEC 62368-1 is an international safety standard that applies to electronic equipment designed for information and communication technology (ICT) and audio-visual (AV) applications. It combines and replaces the long-standing IEC 60950 (ITE applications) and IEC 60065 (AV applications) standards. The standard approaches product safety differently than those it replaced by applying the principles of Hazard Based Safety Engineering (HSBE), which uses a three-block model to identify hazards and determine appropriate safeguards.

Unification and Harmonization


IEC 62368-1 supersedes and unifies 60950-1 and 60065


The US and EU have harmonized the implementation date

The Three Block Model

HBSE visualizes hazards and safeguards utilizing a three-block model that describe the links between energy source, energy-transfer mechanism (figure 1) or safeguard (figure 2), and the user.
