On February 1, 2024, CESI Certification, the certification body affiliated with China Electronics Standardization Institute (CESI), announced the standard change for the energy saving certification for display equipment.

Such change is due to the implementation of the new mandatory standard GB 21520-2023 Minimum allowable values of energy efficiency and energy efficiency grades for displays (hereinafter referred to as "the new standard"). It is released on May 23, 2023, and will replace the currently effective standard GB 21520-2015 (hereinafter referred to as "the old standard") since June 1, 2024. To ensure the effective implementation of the display energy saving certification, the relevant requirements for the implementation of the new version of the standard are clarified by CESI as follows:

-   From the notice issuing date to May 31, 2024, enterprises may voluntarily choose to implement certification in accordance with the new standard or the old standard.

-   Starting from June 1, 2024, all applications for certification shall be certified and issued in accordance with the new standard.

-   For products that have been certified according to the old standard, the holder of the old standard certification should submit the application for the certification conversion under the new standard in time before the first supervision and inspection after the implementation of the new standard on June 1, 2024. All the old standard certification conversion work should be completed by May 31, 2025, at the latest; The certification of the old standard will be suspended after the aforementioned due date. If the certificate conversion is not completed before August 31, 2025, the old standard certificate will be revoked by the certification body.

-   No certificate conversion is required for certified products that have been manufactured, placed on the market, and will no longer be in production before June 1, 2024.

-   The requirements for implementing the new standard for the energy saving certification of display products in this notice shall not exempt the relevant products from the responsibility of complying with the relevant provisions of the Standardization Law of China.

This notice is a very practical guideline for relevant manufacturers regarding how to act during the period of standard conversion.
