About this edition
GB/T 12240-2008 is the current edition. It was issued on 25 June 2008 and has been in force since 1 January 2009, replacing GB/T 12240-1989.
GB/T 12240-1989 has been superseded: a specification that still cites it is citing a withdrawn edition.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 12240-2008 is classified under ICS 23.060.20, in the field of fluid systems and general-purpose components. 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 J16. 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.
