SG 126/24
China has released two new national standards for physical and chemical performance of garments – GB/T 21294-2024 and GB/T 21295-2024 – that will become effective on October 1, 2024.
The Standardization Administration of China has issued two new national product standards:
- GB/T 21294-2024 Testing methods of physical and chemical performance of garments
- GB/T 21295-2024 Requirements of physical and chemical performance of garments
These were included in China’s No. 1 announcement of approved national standards in 2024. They replace the previous versions, GB/T 21294-2014 and GB/T 21295-2014, and will become effective on October 1, 2024.
Scope
The standards contain requirements and testing methods for garments that are mainly made of woven fabrics.
