Classification: ICS 91.100.30, CCS Q14. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there.

Foreword

This document was issued on 6 August 2023 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 March 2024.

Classification: ICS 91.100.30, CCS Q14.

About this edition

GB/T 13476-2023 is the current edition. It was issued on 6 August 2023 and has been in force since 1 March 2024, replacing GB/T 13476-2009.

GB/T 13476-2009 has been superseded: a specification that still cites it is citing a withdrawn edition.

The interval between issue and effect is the transition period. It exists so that producers, laboratories and buyers can requalify products, revise procedures and use up documentation before the new text becomes the one that applies. The date on this page is the official one from the record of the Standardization Administration.

Classification and status

GB/T 13476-2023 is classified under ICS 91.100.30, in the field of construction materials and building. 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 Q14. 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.
