IEC 63461:2024 is concerned with laboratory model testing for Pelton hydraulic turbine models that have a power rating greater than 5 MW. The document outlines the rules for conducting these tests and provides guidelines for handling any disputes that may arise during the testing phases.

The primary objectives of this standard are to:

Identify the relevant terms and quantities used in the context of the test;
Specify the testing methods and measurement techniques to evaluate the hydraulic performance of the model;
Outline the computation methods for results and their comparison with contractual guarantees;
Determine if the contractual guarantees specified within the document have been fulfilled;
And define the scope, content, and structure of the final report.

While the procedures outlined in this document are not typically applicable to machines with lower power ratings, they can be utilized in such cases if there is mutual agreement between the purchaser and the supplier.
