Updates to ISO 8426

摘要

An ISO Standards sub-committee journey to rigorously study and recommend best methods for determining the displacement of a pump SINCE 2018, A GROUP of fluid power volunteer experts has been diligently researching the various methods available for determining the volumetric flow delivery of a pump from experimental data. Two common available standards used for finding the volumetric displacement of a pump are the ISO 8426:2008 standard and the SAE J745-2009-06. The former normative produces diverse values of the displacement at various shaft speeds, and the latter produces different displacement values at various pressure levels.
