About this edition
GB/T 18175-2014 is the current edition. It was issued on 8 July 2014 and has been in force since 1 December 2014, replacing GB/T 18175-2000.
GB/T 18175-2000 has been superseded: a specification that still cites it is citing a withdrawn edition.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 18175-2014 is classified under ICS 71.040.40, in the field of chemical 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 G76. 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.
