Scope

GB/T 10288-2026 is the English-translated version of 羽绒羽毛检验方法.

GB/T 10288-2026 is the Chinese national standard covering how down is tested — the composition analysis that separates down cluster from feather and fibre, the fill power, the oxygen number and the cleanliness, and the species identification that decides whether it is goose or duck.

Down is sold on numbers that are almost impossible to verify by eye, which makes the test method the whole basis of the trade. It replaces GB/T 10288-2016 and has been in force since 1 September 2026.

It was issued on 30 April 2026 and has been in force since 1 September 2026, replacing GB/T 10288-2016. The document is under the responsibility of the China National Light Industry Council.

Foreword

This document was issued on 30 April 2026 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 September 2026.

It replaces GB/T 10288-2016.

The document is under the responsibility of the China National Light Industry Council.

Classification: ICS 59.040, CCS B 45.

3 Classification and status

GB/T 10288-2026 is classified under ICS 59.040, in the field of textile and leather technology. 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 B 45. 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/T prefix marks a recommended national standard. It is not, in itself, law: it becomes binding when a contract names it, when a regulation or a mandatory standard refers to it, or when a producer declares conformity with it. In practice that covers most of the cases in which it will be read — a purchase specification, an inspection agreement or a certification scheme.

The document is under the responsibility of the China National Light Industry Council, which is the body that maintains it and that will answer a formal question about its interpretation.
