Rotodynamic pumps - Hydraulic performance acceptance tests - Grades 1, 2 and 3 (ISO 9906:2012)
ISO 9906:2012 specifies hydraulic performance tests for customers' acceptance of rotodynamic pumps (centrifugal, mixed flow and axial pumps). It is intended to be used for pump acceptance testing at pump test facilities, such as manufacturers' pump test facilities or laboratories. ISO 9906:2012 can be applied to pumps of any size and to any pumped liquids which behave as clean, cold water.
It specifies three levels of acceptance:
grades 1B, 1E and 1U with tighter tolerance;
grades 2B and 2U with broader tolerance;
grade 3B with even broader tolerance.
It 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.

Pompes rotodynamiques - Essais de fonctionnement hydraulique pour la réception - Niveaux 1, 2 et 3 (ISO 9906:2012)
L'ISO 9906:2012 spécifie les essais de performance hydraulique pour l'acceptation par les clients de pompes rotodynamiques (pompes centrifuges, hélico-centrifuges et hélices). Elle est destinée à être utilisée pour l'essai de réception des pompes dans des installations d'essai des pompes, comme les laboratoires ou les installations d'essai des pompes du fabricant. L'ISO 9906:2012 peut s'appliquer aux pompes quelle que soit leur taille et à tous les liquides pompés qui se comportent comme de l'eau froide propre.
Elle spécifie trois niveaux de réception:
niveaux 1B, 1E et 1U pour des tolérances les plus serrées;
niveaux 2B, 2U pour des tolérances plus larges;
niveau 3B pour des tolérances encore plus larges.
Elle est applicable soit à la pompe elle-même sans autre accessoire, soit à une combinaison associant une pompe à tout ou partie de ses accessoires en aval et/ou en amont.
Centrifugalne črpalke - Prevzemni preskus za hidravlične lastnosti - Razredi 1, 2 in 3 (ISO 9906:2012)
Ta mednarodni standard določa preskuse za hidravlične lastnosti za odobritev centrifugalnih črpalk (centrifugalne, mešane in aksialne črpalke, v nadaljnjem besedilu: črpalke) s strani stranke. Ta mednarodni standard je namenjen uporabi za preskuse za odobritev črpalk v objektih za preskušanje črpalk, na primer objektih za preskušanje črpalk ali laboratorijih proizvajalca. Uporablja se lahko za črpalke vseh velikosti in za vsako črpano tekočino, ki ima lastnosti čiste, mrzle vode. Ta mednarodni standard določa tri stopnje odobritve: – stopnje 1B, 1E in 1U z manjšo toleranco; – stopnji 2B in 2U z večjo toleranco; – stopnja 3B s še večjo toleranco. Ta mednarodni standard zadeva samo črpalko brez kakršne koli opreme ali črpalko v povezavi z vso ali delom njene opreme za uporabo proti toku in/ali v smeri toka.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9906 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 2, Methods of
measurement and testing.
This second edition cancels and replaces the first edition (ISO 9906:1999), which has been technically revised.

Introduction
The tests in this International Standard are intended to ascertain the performance of the pump and to compare
this with the manufacturer’s guarantee.
The nominated guarantee for any quantity is deemed to have been met if, where tested according to this International
Standard, the measured performance falls within the tolerance specified for the particular quantity (see 4.4).
INTERNATIONAL STANDARD ISO 9906:2012(E)
Rotodynamic pumps — Hydraulic performance acceptance
tests — Grades 1, 2 and 3
1 Scope
This International Standard specifies hydraulic performance tests for customers’ acceptance of rotodynamic
pumps (centrifugal, mixed flow and axial pumps, hereinafter “pumps”).
This International Standard is intended to be used for pump acceptance testing at pump test facilities, such as
manufacturers’ pump test facilities or laboratories.
It can be applied to pumps of any size and to any pumped liquids which behave as clean, cold water.
This International Standard specifies three levels of acceptance:
— grades 1B, 1E and 1U with tighter tolerance;
— grades 2B and 2U with broader tolerance;
— grade 3B with even broader tolerance.
This International 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.
