What is the difference between EN 60950 and EN 62368?

In the field of electrical safety, standards play a crucial role in ensuring consumer protection and product compliance. Two well-known standards, EN 60950 and EN 62368, cover safety requirements for information technology equipment (ITE) and audio/video (AV) equipment respectively. While both standards address similar safety concerns, there are important differences between them. In this article, we will explore these differences and explain how they impact the design, production, and usage of these types of equipment.

EN 60950: Safety Requirements for ITE Equipment

EN 60950, also known as IEC 60950, covers the safety requirements for ITE equipment. ITE equipment includes devices such as computers, routers, switches, and other electronic products used in offices, homes, and data centers. This standard focuses on protecting users from electric shock, fire hazards, and other potential risks associated with electrical equipment.

One key aspect of EN 60950 is insulation, which ensures that energized parts are properly isolated to prevent accidental contact. This standard also addresses issues like mechanical strength, thermal management, and proper grounding. Compliance with EN 60950 requires rigorous testing and verification to certify that the equipment meets all safety requirements.

EN 62368: Safety Requirements for AV Equipment

EN 62368, previously known as EN 60065 and EN 60950-1, is the newer and more comprehensive standard that replaces EN 60950 for AV equipment. AV equipment includes products like televisions, audio systems, video recorders, and multimedia devices.

The main difference between EN 60950 and EN 62368 lies in their approach to safety. Unlike the prescriptive nature of EN 60950, EN 62368 follows a hazard-based standard. This means that instead of specific requirements, it focuses on identifying hazards associated with the product and implementing measures to mitigate them.

EN 62368 also addresses risks related to energy sources, such as electrical, thermal, optical, and mechanical hazards. It emphasizes risk assessment, the use of safeguards, and protection against abnormal conditions. This approach allows for better adaptability to new technologies and innovations, ensuring long-term safety compliance for AV equipment.

Conclusion

In summary, while both EN 60950 and EN 62368 cover safety requirements for electronic equipment, they differ in their scope and approach. EN 60950 focuses on ITE equipment and follows prescriptive safety requirements, while EN 62368 covers AV equipment and adopts a hazard-based approach. Understanding these differences is essential for manufacturers, designers, and consumers to ensure compliance, safety, and reliable performance of the equipment we use every day.
