1 Scope

GB/T 13306-2011 is the Chinese national standard on plates, in the field of mechanical systems and 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 12 May 2011 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 October 2011. Classification: ICS 21.010, CCS J29. 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.

This Standard specifies the PLATES' types and dimensions, marking, technical requirements, inspection methods, inspection rules, packing, storage and transportation. This Standard is applicable to the nameplates, operational sign plates, illustration plates, line schematic diagram plates, design data chart plates, safety sign plates and others (generally referred to as "plates") of various electromechanical equipment, instruments and apparatuses, and various components. The Chapter "Types and Dimensions" in this Standard is not applicable to the panels, dial plates, trademarks and artistic decoration plates of instruments, apparatuses and household electrical appliances. However, the technical requirements (see Chapter 5) in this Standard may be acted as a reference for the above products.
