This Standard specifies performance acceptance tests for centrifugal, mixed flow and axial pumps (hereafter all referred to as pumps) that are conducted for delivery inspection.

It can be applied to any size and to any pumped liquids which behave as clean, cold water (see 5.7.1A).

It does not cover structural requirements or requirements regarding mechanical characteristics of the pump.

This Standard specifies three levels of acceptance, grade 1, grade 2, and grade 3, which are further classified into the following: grades IB, IE and 1 U with tighter tolerance; grades 2B and 2U with broader tolerance; and grade 3B with even broader tolerance.

Apart from above, there are acceptance grades with other sets of tolerances intended for pumps with a power input of below 10 kW, and acceptance grade 3J (see Annex JA), which is applicable to pumps without reduction of impeller diameter.

This Standard applies either to a pump itself without any fittings or to a combination of a pump associated with all or part of its upstream and/or downstream fittings.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 9906: 2012 Rotodynamic pumps—Hydraulic performance acceptance tests—Grades 1, 2 and 3 (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
