1 Scope

GB/T 16907-2014 is the Chinese national standard on technical specifications for centrifugal pumps (class i), in the field of fluid systems and general-purpose 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 6 May 2014 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 2014. Classification: ICS 23.080, CCS J71. 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 centrifugal pump (hereinafter referred to as the pump) terms and definitions, design, materials, factory inspection and testing, shipment preparation, responsibility. This standard applies to industrial pumps under high demand conditions. This standard does not apply to storage pumps, oil, natural gas and heavy chemical industrial pumps.
