Scope
GB/T 16774-2012 is the English-translated version of 自增压式液氮容器.
GB/T 16774-2012 is the Chinese national standard on autoboosting caliber liquid nitrogen container, in the field of fluid systems and general-purpose components.
The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it.
It was issued on 31 December 2012 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2013.
Classification: ICS 23.020, CCS B90. 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.
The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
