What is the difference between IEC 62368 and 60950?

When it comes to ensuring the safety of electronic equipment, there are various international standards that manufacturers need to comply with. Two such standards are IEC 62368 and 60950. In this article, we will explore the differences between these two standards and how they affect the design and manufacturing of electronic products.

of IEC 62368

IEC 62368, also known as "Audio/Video, Information and Communication Technology Equipment – Safety Requirements," is a standard developed by the International Electrotechnical Commission (IEC) that covers a wide range of electronic equipment. It is a relatively new standard that was published in 2010 and later revised in 2018 to replace IEC 60950.

This standard is based on the principle of hazard-based safety engineering and focuses on the identification and elimination of potential hazards during the design and manufacturing process. It takes into account various factors, such as electrical safety, fire hazards, mechanical risks, and energy hazards.

Understanding IEC 60950

IEC 60950, also referred to as "Information Technology Equipment – Safety – General Requirements," was a widely adopted standard before the of IEC 62368. It was first published in 1999 and covered a broad range of electronic devices used in information technology applications.

This standard emphasized compliance with specific safety requirements, including protection against electric shock, energy hazards, and fire risks. However, over time, it became evident that the rapid advancements in technology necessitated a more comprehensive and flexible approach to safety standards.

Differences in Scope and Approach

One significant difference between IEC 62368 and 60950 is the scope of equipment covered. While IEC 60950 primarily focused on information technology equipment, IEC 62368 extends its coverage to include audio/video and communication technology devices as well. This expansion allows for a more comprehensive approach to safety, considering the increasing convergence of technologies.

Another fundamental difference lies in the approach taken by these standards. IEC 60950 follows a prescriptive approach, providing specific guidelines and requirements that manufacturers must meet. On the other hand, IEC 62368 adopts a hazard-based approach, which encourages designers and manufacturers to identify potential hazards and mitigate them using engineering principles.

Transition from IEC 60950 to 62368

With the publication and revision of IEC 62368, the transition from IEC 60950 to the newer standard has been initiated. The phase-out period began in 2010, allowing manufacturers and certification bodies sufficient time to adapt to the new requirements. However, it is important to note that some regions or countries may have their own specific timelines for the transition.

Manufacturers are encouraged to familiarize themselves with the requirements of IEC 62368 and seek guidance from certification bodies to ensure compliance. The updated standard provides a more flexible framework, enabling manufacturers to adapt to changing technology trends while maintaining a high level of safety.

In conclusion, while IEC 60950 was widely adopted for many years, the of IEC 62368 signifies a shift towards a more comprehensive and flexible approach to safety standards. The broader scope and hazard-based approach of IEC 62368 enable better protection against potential risks associated with modern electronic equipment.
