Rotodynamic pumps — Hydraulic performance acceptance tests — Grades 1, 2 and 3

Edition date: 2012-04-26
In Force
Available languages: English, French
Summary:

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.



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.
