What is the difference between UL62368 and UL60950?

Introduction

When it comes to electrical safety standards, UL62368 and UL60950 are two widely recognized certifications. Both standards ensure the safety and reliability of electronic equipment, but they have some distinct differences. In this article, we will take an in-depth look at these standards and explore their variances.

UL62368: The Modern Standard

UL62368, also known as the "Audio/Video, Information, and Communication Technology Equipment – Safety Requirements," is a relatively new standard that replaces UL60950. It takes into account advancements in technology and aims to provide a more comprehensive approach to safety.

The key difference between UL62368 and its predecessor is the basis of their evaluation. While UL60950 focused on specific product types, UL62368 adopts a hazard-based approach. This means that instead of looking at individual product categories, UL62368 assesses the potential risks associated with any electronic equipment.

UL60950: The Traditional Standard

UL60950, or the "Safety of Information Technology Equipment," has been the dominant safety standard for many years. It was developed when traditional computing and telecommunication devices were the primary focus.

Unlike UL62368, which evaluates hazards in a broader sense, UL60950 is product-specific. This means that manufacturers need to meet different requirements depending on the type of product being certified, such as power supplies, IT equipment, or audio/video devices.

Differences in Test Methods

Another notable difference between UL62368 and UL60950 lies in their test methods. UL60950 primarily revolves around mechanical and electrical safety concerns, while UL62368 expands on these areas by emphasizing additional aspects like energy hazards.

UL62368 also introduced a new concept called "energy source independence." This means that equipment should be designed to operate safely with various types of power sources, including batteries and renewable energy systems. UL60950 does not have such a requirement.

Conclusion

In summary, UL62368 and UL60950 are two important safety standards for electronic equipment. UL62368 takes a hazard-based approach and considers energy source independence, making it a more versatile and comprehensive standard. On the other hand, UL60950 remains relevant for specific product categories and is well-established in the industry. Ultimately, the choice between the two standards depends on the type of equipment being certified and the desired level of safety assurance.
