What is the difference between UL 60950 and 62368?

Electrical safety standards are crucial in ensuring that products are safe for consumers to use. Two commonly referenced standards in the industry are UL 60950 and UL 62368. While they both pertain to safety, there are significant differences between them. This article aims to provide a thorough comparison of these two standards.

UL 60950: Safety of Information Technology Equipment

UL 60950 is a safety standard specifically designed for information technology equipment (ITE). This includes devices such as computers, servers, routers, and telecommunication equipment. The primary objective of UL 60950 is to assess the potential electrical, fire, and mechanical hazards associated with these devices.

One key aspect of UL 60950 is that it follows a component-level approach. This means that each individual component within the device must comply with certain safety requirements. Additionally, the standard takes into consideration environmental factors such as humidity, temperature, and altitude, which can affect the performance and safety of the equipment.

UL 62368: Audio/Video, Information, and Communication Technology Equipment

UL 62368 is a newer safety standard that replaces UL 60950 in many regions. It encompasses a broader range of equipment, including audio/video, information, and communication technology (AV-ICT) devices. This standard was developed to address the convergence of technologies and the need for more comprehensive safety regulations.

Unlike UL 60950, which focuses on specific components, UL 62368 adopts a functional safety approach. It evaluates the entire system, considering how different components interact and identifying potential risks. This holistic approach is especially relevant for modern AV-ICT devices, which often integrate multiple functions and technologies.

Differences in Testing and Certification

When it comes to testing and certification, UL 60950 and UL 62368 also diverge. UL 60950 uses predefined testing procedures, which are well-established and widely accepted within the industry. The focus is on verifying compliance with specific safety criteria, ensuring that electrical insulation, grounding, and other safety measures are adequate.

On the other hand, UL 62368 allows for more flexibility in the testing process. Instead of following rigid testing protocols, manufacturers have the freedom to choose appropriate methods and techniques to demonstrate compliance with the standard's requirements. This shift enables innovation and accommodates the evolving nature of AV-ICT products.

The Roadmap to Transition

Many countries around the world have adopted UL 62368 as the new safety standard for AV-ICT equipment. However, this transition does not happen overnight. Manufacturers and regulatory bodies need time to adjust their processes and ensure a smooth switch from UL 60950 to UL 62368.

It is important to note that both UL 60950 and UL 62368 serve the same fundamental purpose – to protect users from potential hazards. As technology continues to advance, safety standards must evolve accordingly. Understanding the differences between these two standards can help manufacturers, regulators, and consumers stay informed and make well-informed decisions regarding product safety.
