Rotodynamic pumps - Hydraulic performance acceptance tests - Grades 1 and 2 (ISO 9906:1999)

This standard deals with hydrolic performance tests for acceptance of rotodynamic pumps.

Kreiselpumpen - Hydraulische Abnahmeprüfung Klassen 1 und 2 (ISO 9906:1999)

Diese Internationale Norm hat Abnahmeprüfungen an Kreiselpumpen (Radial-, Halbaxial- und Axialpumpen, im Folgenden einfach als ¿Pumpen" bezeichnet) zum Gegenstand. Sie bezieht sich auf Pumpen jeglicher Größe, die mit Flüssigkeiten geprüft werden, die sich wie reines, kaltes Wasser verhalten (siehe 5.4.5.1). Sie befasst sich weder mit den baulichen Einzelheiten der Pumpen noch mit den Festigkeitseigenschaften ihrer Bauteile.
Wie im Vorwort beschrieben, enthält die vorliegende Internationale Norm zwei Messgenauigkeitsklassen: Klasse 1 für höhere Genauigkeit und Klasse 2 für geringere Genauigkeit. Diese Klassen beinhalten verschiedene Werte für Toleranzfaktoren, zulässige Schwankungen und Messunsicherheiten.
Die höheren Toleranzfaktoren für Serienpumpen, die nach Katalog-Kennlinien ausgewählt werden, sowie für Pumpen mit einem Leistungsbedarf von weniger als 10 kW sind in Anhang A enthalten.
Diese Internationale Norm kann entweder allein auf die Pumpe ohne Rohrleitungsteile oder auf die Pumpe mit allen oder einem Teil der zugehörigen stromaufwärts bzw. stromabwärts angeordneten Rohrleitungsteilen angewendet werden.

Pompes rotodynamiques - Essais de fonctionnement hydraulique pour la réception - Niveaux 1 et 2 (ISO 9906:1999)

La présente Norme internationale spécifie des essais de fonctionnement hydraulique pour la réception des pompes rotodynamiques (pompes centrifuges, hélico-centrifuges et hélices simplement désignées «pompes» dans la suite). Elle peut s'appliquer aux pompes de toutes tailles et à tous les liquides pompés se comportant comme l'eau propre et froide telle que définie en 5.4.5.2. Elle ne concerne pas les détails de structure de la pompe ni les propriétés mécaniques de ses composants.La présente Norme internationale contient deux niveaux de précision de mesurage: le niveau 1 pour la précision la plus élevée et le niveau 2 pour la précision la plus faible. Ces niveaux incluent différentes valeurs pour les facteurs de tolérance, les fluctuations admissibles et les incertitudes de mesurage.Pour les pompes produites en série selon le choix fait à partir des courbes de performances typiques et pour les pompes de puissance inférieure à 10 kW, voir l'annexe D pour des facteurs de tolérance supérieure.La présente Norme internationale est applicable soit à la pompe elle-même sans accessoire, soit à une combinaison d'une pompe associée à tout ou partie de ses accessoires à l'aval et/ou à l'amont.
