Description / Abstract:
This part of ISO 17769 specifies terms, letter symbols and units
related to the flow of liquids through rotodynamic and positive
displacement liquid pumps and associated installations. It serves
as a means of clarifying communications between the installation
designer, manufacturer, operator and plant constructor. This part
of ISO 17769 identifies the units in common usage, but all
additional legal units can be used.
This part of ISO 17769 deals solely with conditions described by
positive values for the rate of flow and pump head.
This part of ISO 17769 is not concerned with terms, letter
symbols and units referring to the component parts of rotodynamic
and positive displacement pumps and installations.
Whenever possible, symbols and definitions conform to those used
in ISO 80000-1, with further explanations where these are deemed
appropriate. Some deviations are incorporated for reasons of
consistency.
NOTE In addition to terms used in the three official ISO
languages (English, French and Russian), this document gives the
equivalent terms in German; these are published under the
responsibility of the member bodies for France (AFNOR), Russia
(GOST R) and Germany (DIN), and are given for information only.
Only the terms and definitions given in the official languages can
be considered as ISO terms and definitions.
