is the definitive international standard titled "Field acceptance tests to determine the hydraulic performance of hydraulic turbines, storage pumps and pump-turbines" . Established by the International Electrotechnical Commission (IEC), it provides a rigorous framework for verifying that hydropower machinery meets its contractual performance guarantees in real-world operating conditions.
: It allows for the analysis of a machine's actual behavior in the field compared to its design model.

: Covered extensively in Clause 14, this method is used for measuring efficiency, particularly in high-head applications.
: The standard excludes purely commercial topics and detailed structural or mechanical design. If you successfully obtain the , here is
The standard is divided into logical sections to guide engineers through the complex process of field testing:
: Procedures for computing results and assessing systematic uncertainties to ensure accuracy. The standard is divided into logical sections to
Applies to hydraulic energy engineering (ICS 27.140), focusing on steady-state and transient operating conditions while excluding purely commercial topics. Where to Find the PDF
This is the longest section. For each method, the standard provides:
: Specifications for the precision and types of instruments needed for measurements like flow, pressure, and temperature. Efficiency Measurement Methods :
One of the most challenging aspects of hydraulic testing is measuring the volume of water passing through the turbine. IEC 60041 details several methods for this, ranking them by accuracy:
