1 Scope

GB/T 11705-2009 is the Chinese national standard on test method for marine electric three-spindle screw pump, in the field of shipbuilding and marine structures. 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 9 March 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 November 2009. Classification: ICS 47.020.50, CCS U47. 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 electric three screw (hereinafter referred to as pump) test items, test methods, calculation of test results, etc. This standard applies to the ship transporting fuel, oil and hydraulic oil clean lubricating medium (flow 0.18m3/h ~ 720m3/h, Outlet pressure 0.2MPa ~ 25MPa, shaft power 0.25kW ~ 600kW, net absorption height + 0.02MPa ~ -0.06MPa) pump Test.
