What is 62368 Class of Equipment?

The 62368 class of equipment refers to a set of safety standards established by the International Electrotechnical Commission (IEC), specifically IEC 62368-1. These standards define the requirements for the safety and performance of audio, video, information, and communication technology equipment.

Background and Purpose

The previous standards, IEC 60065 for audio equipment and IEC 60950 for information technology equipment, were combined to create a unified standard for modern devices that integrate various technologies. The purpose of IEC 62368-1 is to ensure that these products are safe to use and do not pose any risks to the operators or end-users.

Unlike the previous standards which were prescriptive in nature, the 62368 standard takes a more comprehensive approach by focusing on the identification and assessment of hazards associated with equipment. It employs principles of safety engineering to eliminate, reduce, or control these hazards to an acceptable level.

Key Requirements

One of the key requirements set forth by IEC 62368-1 is the adoption of a hazard-based safety engineering process. This involves identifying potential hazards during both normal and abnormal operation of the equipment and taking appropriate measures to mitigate the risks associated with them. Manufacturers must conduct thorough risk assessments and document their findings, ensuring that effective safety controls are implemented throughout the design and production process.

Another important aspect is the consideration of foreseeable misuse, such as unintended or incorrect operation of the equipment. Manufacturers must take steps to prevent potential risks arising from such misuse by incorporating safety features and providing clear instructions and warnings to the users.

Implementation and Compliance

Manufacturers and designers of audio, video, information, and communication technology equipment are responsible for ensuring their products meet the requirements set forth by IEC 62368-1. Compliance with these standards is essential for obtaining relevant certifications and securing market access in many countries.

Before a product to the market, it is crucial for manufacturers to conduct thorough testing and evaluation to ensure their equipment meets the safety and performance criteria specified in the 62368 standard. Third-party testing laboratories can assist in this process, providing reliable certification services.

In conclusion, the 62368 class of equipment encompasses a comprehensive safety standard for audio, video, information, and communication technology devices. Adhering to these standards ensures that products are safe to use, mitigating potential risks to both operators and end-users. Manufacturers must incorporate hazard-based safety engineering principles, consider foreseeable misuse, and comply with all requirements to meet the highest safety standards in today's rapidly evolving technological landscape.
