1 Scope

GB 5369-2008 is the Chinese national standard on gerneral-specification for drinking water tank coating of shipbuilding, in the field of paint and colour industries. 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 30 December 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 December 2009. Classification: ICS 87.040, CCS G51. 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 marine water tank coatings requirements, test methods, inspection rules, marking, packaging, transportation and storage. This standard applies to the coated surface of the coating system of the ship drinking water tanks.
