Scope

This standard only specifies the requirements for the geometric similarity of prototypes and models of hydraulic turbines, and stipulates the accuracy of control dimensions and the surface quality of flow components that affect the hydraulic performance of hydraulic turbines, storage pumps, and pump-turbines. This standard applies to models and prototypes of hydraulic turbines, storage pumps, and pump-turbines that meet one of the following conditions: a) Power of 10 MW or more; b) Francis turbines with a nominal diameter of 1.0 m or more; c) Axial flow, radial flow, and diagonal flow turbines with a nominal diameter of 3.3 m or more; d) Centrifugal storage pumps with a nominal diameter of 1.0 m or more; e) Impulse hydraulic turbines with a nominal diameter of 1.0 m or more. Prototypes of hydraulic turbines, storage pumps, and pump-turbines with smaller dimensions and capacities than the above conditions may be used for reference.
