What is UL 62368

Underwriters Laboratories (UL) is a renowned global safety certification organization. UL 62368 is a standard developed by UL for the safety of audio/video, information, and communication technology equipment. This thorough technical article aims to provide an in-depth understanding of UL 62368.

Introduction to UL 62368

UL 62368, also known as the "Audio/Video, Information and Communication Technology Equipment - Safety Requirements" standard, is applicable to a wide range of products, including but not limited to desktop computers, servers, televisions, monitors, printers, routers, and speakers. It provides guidelines and requirements for manufacturers to ensure the safety of their products during normal operation, foreseeable misuse, and fault conditions.

Main Principles of UL 62368

UL 62368 is based on the principle of hazard-based safety engineering, which focuses on identifying potential hazards associated with the product's design, materials used, and intended use. It emphasizes proactive mitigation strategies through design techniques such as insulation, protective barriers, and grounding. The standard also includes requirements for temperature rise, flame resistance, electrical hazards, mechanical hazards, and radiation hazards.

Transition from UL 60950 to UL 62368

UL 62368 is replacing the earlier UL 60950 standard for IT and audio/video equipment. The transition from UL 60950 to UL 62368 is driven by technological advancements and the recognition of emerging hazards. UL 62368 takes a more holistic approach towards safety, encompassing new types of equipment and addressing various risk factors that were not adequately covered in the previous standard. Manufacturers are encouraged to understand and comply with UL 62368 in order to ensure the safety of their products and meet market requirements.
