GB/T 19249-2017Reverse osmosis water treatment equipment (English PDF)

1 Scope

GB/T 19249-2017 is the Chinese national standard on reverse osmosis water treatment equipment, in the field of construction materials and building. 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 29 December 2017 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 November 2018. Classification: ICS 91.140.60, CCS P41. 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 terms and definitions, classification and types, requirements, test methods, inspection rules, marking, packaging, transportation and storage of reverse osmosis water treatment equipment (hereinafter referred to as equipment). This Standard applies to equipment which uses reverse osmosis water membrane (including spiral wound type and disk-tube type) technology for the desalting, purification and separation treatment of water.
