What is the difference between UL 62368-1 and 60950-1

In the field of electrical safety standards, there are two important regulations that dictate the design and safety requirements for electronic equipment – UL 62368-1 and 60950-1. While both address similar concerns, they differ in their approach and scope. This article will explore the key differences between UL 62368-1 and 60950-1, highlighting their distinct features and applications.

UL 62368-1: A Modern Approach to Safety

UL 62368-1, also known as the standard for audio/video, information, and communication technology equipment, outlines the safety requirements for various modern electronic products. It employs a hazard-based approach, focusing on identifying potential risks associated with energy sources, component failure, and other factors. This new approach allows for more flexibility and adaptability to evolving technologies, ensuring the safety of users and facilitating innovation in product designs.

60950-1: Classic Safety Standards

60950-1, on the other hand, is an older safety standard that addresses the general safety requirements for information technology equipment. It emphasizes compliance with a set of predefined specifications, providing specific guidelines for different types of electronic products. Compared to UL 62368-1, it is less flexible when it comes to accommodating new technologies, but it remains widely recognized and accepted in many industries.

Key Differences Between UL 62368-1 and 60950-1

One of the main differences between UL 62368-1 and 60950-1 lies in their risk assessment methodology. While UL 62368-1 utilizes a hazard-based system encompassing three levels of severity (low, medium, and high), 60950-1 follows a more prescriptive approach, outlining specific safety requirements based on historical experience and industry consensus.

Another notable distinction is the scope of coverage. UL 62368-1 has a broader range of applicability, encompassing a wide variety of products that fall within the category of audio/video, information, and communication technology equipment. Conversely, 60950-1 focuses primarily on traditional IT equipment, such as computers, printers, and servers.

Conclusion

In summary, UL 62368-1 and 60950-1 are two important safety standards for electronic equipment, each with its own unique approach and focus. UL 62368-1 takes a hazard-based perspective, catering to modern technologies and enabling innovative designs, while 60950-1 follows a more traditional, specification-based approach that is widely recognized in the industry. Both standards play significant roles in ensuring product safety and should be considered based on the specific requirements and applications of the electronic products being developed or manufactured.
