Time：
2023-09-13
IECEE officially released the standard IEC 62368-1:2023 (4th edition) TRF for audio, video, information technology, and communication technology equipment, preparing for the implementation and application of the new standard.
After the International Electrotechnical Commission (IEC) released the fourth edition of the standard IEC 62368-1:2023 for audio, video, information technology, and communication technology equipment on May 26, 2023, IECEE finally released the TRF template on August 18, 2023, preparing for the implementation and application of the new standard.
Update and changes to the fourth edition of IEC62368-1 standard:
The main changes included in the fourth edition of IEC 62368-1 compared to the third edition are as follows:

-Clause 4.1.9:
Added requirement for voltage measuring instruments, unless otherwise specified, the internal resistance of voltage measuring instruments must be at least 1M Ω
-Clause 4.8.1:
If the product is unable to remove the button battery from the product due to the position of the battery, the requirements of this clause do not apply, but the warning requirements of 4.8.2 still apply
-Clause 4.8.3:
Updated requirements for button battery compartment opening method
