Foreword
This document was issued on 24 July 2024 by the State Administration for Market Regulation and the Standardization Administration of the People's Republic of China, and has been in force since 1 August 2025.
It replaces GB/T 40559-2021.
Classification: ICS 29.220.99, CCS K82.
3 Classification and status
GB 40559-2024 is classified under ICS 29.220.99, in the field of electrical engineering. ICS is the International Classification for Standards, the same scheme used by ISO and by the national bodies of most countries, which is what allows a Chinese standard to be placed beside its foreign counterparts on subject rather than on number.
Its Chinese Standard Classification code is CCS K82. CCS is the domestic scheme, a letter for the sector and two digits for the subject within it, and it is the code by which the standard is filed and searched in China.
The GB prefix without a suffix marks a mandatory national standard: compliance is required by law for the products or activities within its scope, and a product that does not meet it may not lawfully be placed on the Chinese market.
