The IEC standard 60041 'field acceptance tests to determine the hydraulic performance of hydraulic turbines, storage pumps and pump turbines' proposes in section 4.2 that both parties, i.e. the purchaser (operator) and the manufacturer of the hydraulic machinery, should have the same rights to select the efficiency measurement method and to appoint the appropriate measuring team. However the details should be fixed in a contract. It is suggested that an independent expert accompanies the entire process. This expert should be present at the kick-off meeting of the efficiency measurement and during the actual testing.
