What is the difference between EN62368 and EN60950?

EN62368 and EN60950 are both safety standards commonly used in the electrical and electronic industries. These standards provide guidelines to ensure that devices and equipment are safe for use. While they may seem similar, there are significant differences between the two.

Scope and Application

EN62368, also known as IEC62368, is a relatively new standard that replaced EN60950-1, which applies specifically to audio/video, information, and communication technology equipment. It covers a wide range of products such as computers, monitors, printers, modems, and telecommunication devices. On the other hand, EN60950 focuses on general-purpose electrical equipment that operates at voltages not exceeding 1000V AC or 1500V DC. This includes home appliances, power supplies, and laboratory equipment.

Risk Assessment Approach

One of the key differences between EN62368 and EN60950 lies in the risk assessment approach. EN62368 utilizes a hazard-based safety engineering (HBSE) method, which requires manufacturers to identify potential hazards and assess risks associated with product use. This allows for a more comprehensive evaluation of safety hazards and facilitates the implementation of control measures to mitigate these risks. In contrast, EN60950 uses a prescriptive approach, specifying certain design and construction requirements that must be met to comply with the standard.

Global Harmonization and Transition

Another important distinction between EN62368 and EN60950 is their global harmonization status and transition period. EN62368 is part of a global standard series called IEC62368, which has been adopted by various countries worldwide, including the European Union, United States, Canada, and Japan. The transition period from EN60950 to EN62368 varies depending on the region. In some countries, it is already mandatory to comply with EN62368, while in others, manufacturers may still choose to use either standard. However, most countries are moving towards full adoption of EN62368 as the new safety benchmark.
