BS EN ISO 9906: 2000 Rotodynamic pumps - Hydraulic Performance Acceptance Tests - Grades 1 and 2

This International Standard combines and replaces the former acceptance test standards ISO 3555:1977 and ISO 2548:1975, but there is an important change in the verification of guarantees, because the uncertainty of measurement must not influence the acceptability of a pump and the tolerances are due to constructional differences only.
