What is IEC 62368-1 Ed.3:2018?

IEC 62368-1 Ed.3:2018, also known as IEC 62368-1 Third Edition, is an international safety standard for audio/video and information technology equipment. It was developed by the International Electrotechnical Commission (IEC) to provide a comprehensive set of requirements for product manufacturers to ensure the safety of their equipment.

The Purpose and Scope of IEC 62368-1 Ed.3:2018

The primary purpose of IEC 62368-1 Ed.3:2018 is to harmonize the safety requirements for audio/video and information technology equipment globally. The standard takes into consideration the convergence of technologies and the blurring of boundaries between traditional AV and IT products. Its scope covers a wide range of equipment, including but not limited to televisions, computers, printers, projectors, audio systems, and routers.

Key Changes in IEC 62368-1 Ed.3:2018

Compared to its predecessor IEC 62368-1 Ed.2, the third edition introduces several significant changes. One notable change is the shift from prescriptive requirements to a more performance-based approach. Instead of specifying specific materials or construction methods, the standard focuses on evaluating the potential hazards associated with a product's energy sources and assessing its overall performance in mitigating those hazards.

Another key change is the inclusion of Annex ZZ, which provides a transitional period for manufacturers to comply with the new requirements. This allows existing products that were certified under the previous edition of the standard to continue being sold without immediate retesting or redesign, as long as they meet certain criteria. However, it is important for manufacturers to plan for the transition and ensure their products are compliant with the latest edition within the specified timeframe.

Benefits of Compliance

Complying with IEC 62368-1 Ed.3:2018 offers several benefits for both manufacturers and consumers. By adopting a performance-based approach, the standard allows manufacturers greater flexibility in design and innovation while still ensuring product safety. This can lead to improved product quality and enhanced user experience.

For consumers, compliance with the standard provides assurance that the equipment they purchase has undergone thorough testing to meet stringent safety requirements. It reduces the risk of accidents, injuries, or property damage caused by faulty or unsafe products. Additionally, compliance with international standards enhances global market access for manufacturers, as many countries align their safety regulations with IEC standards.
