This International Standard covers the Class I (most severe) requirements for centrifugal pumps used in various industries. It consists of a basic text covering general requirements. The technical requirements refer only to the pump unit. Storage pumps are not included in this International Standard. A separate standard will be issued by IEC. This International Standard includes design features concerned with installation, maintenance and safety of such pumps, including baseplate, coupling and auxiliary piping. Where this International Standard specification has been called for:
a) and requires a specific design feature, alternative designs may be offered which meet the intent of this International Standard, provided that the alternative is described in detail;
b) pumps not complying with all requirements of this International Standard may be offered for consideration, provided that all deviations are stated.
Die technischen Anforderungen an Kreiselpumpen der Klasse 1 (höchste Anforderungsstufe) sind festgelegt; diese gelten nur für das Pumpenaggregat. Kriterien für die Auswahl der Anforderungsklasse für einen bestimmten Anwendungsfall können auf Verfügbarkeit, Arbeitsbedinungen, Umweltbedingungen u. a. basieren. Die Grundlagen für eine Werksinspektion sowie die notwendigen Prüfungen der Pumpe sind angegeben. Die Verantwortlichkeiten sind eindeutig geregelt.
