1 Scope

GB 19454-2009 is the Chinese national standard on safety code for inspection of portable tanks for dangerous goods. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 21 June 2009 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 May 2010. Classification: ICS , CCS A80. 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 requirements for dangerous goods in portable tanks, marking, performance testing, the use of identification. This standard applies to the shipment of Class 3 to Class 9 dangerous goods portable tank inspection.
