DESCRIPTION
BS ISO 20155:2017
This standard BS ISO 20155:2017 Ships and marine technology. Test method of flow induced in-pipe noise source characteristics for a ship-used pump is classified in these ICS categories:
- 47.020.01 General standards related to shipbuilding and marine structures
This document specifies a test method for determining flow induced in-pipe noise source characteristics of a ship-used pump as a two-port sound source in laboratory conditions by measuring acoustic pressures in the pipe reaches of inlet and outlet.
The test method is applicable to all types of centrifugal pumps with a diameter over 50 mm operating under steady conditions.
The suitable frequency range of the test method is about 10 Hz to 1 000 Hz, and the upper frequency is dependent on the inner diameter of the pipe, in which the plane acoustic wave propagates.
