1 Scope

GB/T 22112-2008 is the Chinese national standard on industrial process measurement and control instruments - arrangement and marking of connecting terminals, in the field of manufacturing engineering. 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 30 June 2008 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 January 2009.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the industrial automation instruments and sheet connected terminals are arranged and logo. This standard applies to disk-mounted terminal blocks of industrial automation instruments and sheet connected (hereinafter referred to as terminal); terminal non-panel-mounted instrument Also refer to the use of child. This standard does not apply to non-terminal terminal board (eg connector) or special occasion requirements (eg explosion) instrument table outer joins.
