Scope: This standard provides the cavitation guarantee specifications for the bucket turbine runner and serves as the basis for the measurement and evaluation of the cavitation amount of the bucket turbine. The power, hydraulic specific energy (water head), rotational speed, material and operation of the bucket turbine Conditions should be specified in the contract. ' The measurement and assessment terms of the amount of cavitation in this standard are carried out on the basis of material weight loss within a given period of time and under specified operating conditions. When cavitation erosion is likely to occur in the whole or some operating range of the Pelton turbine, it is necessary to limit the degree of cavitation erosion at the end of the operation period specified in the contract in the form of guarantee. Such assurance shall include limitations on the range of operation consistent with the specified operating conditions.
