IEC 62097:2019

IEC 62097:2019 is the technical reference for hydraulic machines, radial and axial, and the methodology used for performance transposition from model to prototype. It is relevant where engineering teams need a defensible way to compare test results from scaled models with full-size equipment during design review, verification activities, and conformity assessment. For organizations involved in procurement, laboratory evaluation, or technical documentation, IEC 62097:2019 supports more consistent performance interpretation and a clearer basis for documented evaluation.

Purpose of IEC 62097:2019

The purpose of this document is to define how performance data obtained from a hydraulic machine model can be transposed to the prototype in a controlled and technically consistent manner. That matters in projects where radial or axial hydraulic machines are evaluated before installation or acceptance. By aligning the methodology, engineers can support technical validation, reduce ambiguity in performance comparison, and improve the reliability of review processes used for operational consistency, risk management, and compliance preparation.

Compliance applications of IEC 62097:2019

IEC 62097:2019 is commonly used in engineering documentation and testing workflows for hydropower-related equipment where model testing forms part of the acceptance or assessment process. It may be referenced by manufacturers, test laboratories, consultants, and asset owners when reviewing prototype performance expectations, preparing procurement specifications, or documenting technical compliance. The methodology is particularly useful when a project requires a traceable basis for comparing model results with prototype behavior during technical assessment or regulatory preparation.

Benefits of IEC 62097:2019

Using IEC 62097:2019 helps support more consistent evaluation of performance data across model and prototype stages, which can improve engineering validation and reduce interpretation differences between stakeholders. It can also strengthen quality workflows by giving teams a recognized framework for documented evaluation and testing consistency. For procurement and conformity assessment, the document provides a clearer technical reference for comparing offers, reviewing verification activities, and managing performance-related risk in hydraulic machine projects.
