Attention! The new standard GB 21520-2023 for energy-saving certification of displays has been officially implemented since June 1, 2024

Author:中認聯(lián)科 time:2024-06-18 Ctr:367

On May 23rd, 2023, the new standard GB 21520-2023 "Limited Value and Grade of Energy Efficiency of Display" (hereinafter referred to as the "new standard") was released, and will be officially implemented on June 1st, 2024, replacing the original GB 21520-2015 standard (hereinafter referred to as the "old standard").

The main changes of the new standard are:

Product name and scope of application: The new version of the standard changes "computer monitor" to "monitor", and increases the energy efficiency requirements of organic light-emitting diode (OLED) display and LED integrated display terminal.

◆ Certification standard: The new standard GB 21520-2023 replaced the old standard GB 21520-2015, and became the latest basis for energy-saving certification of displays.

◆ Revision of certification rules: China Quality Certification Center (CQC) revised the certification rules for display energy conservation and issued CQC31-452629-2023 "Certification Rules for Display Energy Conservation", which replaced the original CQC31-452629-2016 "Certification Rules for Computer Display Energy Conservation".

Detailed changes in the new version of the standard

◆ Expanded scope of application: The new standard is not only applicable to traditional computer monitors, but also covers OLED displays and LED integrated display terminals, which reflects the concern for new technologies and new products.

Update of terms and definitions: The new version of the standard adds terms and definitions such as "LED integrated display terminal", "working state" and "working state power", and changes terms such as "off state", "sleep state" and "energy efficiency" to better adapt to the development of new technologies and new products.

◆ Changes in energy efficiency grade requirements: The new version of the standard has changed the energy efficiency grade requirements of LCD monitors, OLED monitors and LED integrated display terminals, and increased the energy efficiency grade requirements of high-performance LCD monitors, high-performance OLED monitors and high-performance LED integrated machines, so as to promote the further improvement of product energy efficiency.

◆ Test method update: The new standard has changed the test methods of energy efficiency, sleep state power and off state power of displays, and added relevant test requirements for OLED displays and LED integrated machines to ensure the accuracy and reliability of test results.

The relevant requirements for the implementation of the new standard are as follows:

★ Transitional period arrangement: From the date of publication of the new standard to May 31, 2024, enterprises can voluntarily choose to implement certification according to the new standard or the old standard. Since June 1, 2024, the new version of the standard should be adopted for certification and the new version of the standard certification certificate should be issued, and the old version of the standard certification certificate will no longer be issued.

★ Certificate renewal: For products that have been certified according to the old standard, the holder of the old standard certification certificate shall submit an application to CQC for converting the new standard certification certificate in time, and complete the product confirmation and certificate renewal according to the new standard after the implementation date of the standard and before the end of the first follow-up inspection. The conversion of all old standard certificates should be completed by May 31, 2025 at the latest; If it is not completed within the time limit, CQC will suspend the old standard certification certificate; For certificates that have not been converted on August 31, 2025, CQC will revoke the old standard certificate.

★ Annual review: For products that have been certified according to the old standards, the annual review must be completed after June 1, 2024. If the version has not been changed, the factory will not pass.
