This document applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This document applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size. Nevertheless, this document may be used for such machines by agreement between the purchaser and the supplier. In this document, the term "turbine" includes a pump-turbine operating as a turbine and the term "pump" includes a pump-turbine operating as a pump. This document excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests. This document is concerned with neither the structural details of the machines nor the mechanical properties of their components, so long as these do not affect model performance or the relationship between model and prototype performances. This document covers the arrangements for model acceptance tests to be performed on hydraulic turbines, storage pumps and pump-turbines to determine if the main hydraulic performance contract guarantees (see 4.2) have been satisfied. It contains the rules governing test conduct and prescribes measures to be taken if any phase of the tests is disputed. The main objectives of this document are: - to define the terms and quantities used; - to specify methods of testing and of measuring the quantities involved, in order to ascertain the hydraulic performance of the model; - to specify the methods of computation of results and of comparison with guarantees; - to determine if the contract guarantees that fall within the scope of this document have been fulfilled; - to define the extent, content and structure of the final report. The guarantees can be given in one of the following ways: - guarantees for prototype hydraulic performance, computed from model test results considering scale effects; - guarantees for model hydraulic performance. Moreover, additional performance data (see 4.4) can be needed for the design or the operation of the prototype of the hydraulic machine. Contrary to the requirements of Clauses 4 to 6 related to main hydraulic performance, the information of these additional data given in Clause 7 is considered only as recommendation or guidance to the user (see 7.1). It is particularly recommended that model acceptance tests be performed if the expected field conditions for acceptance tests (see IEC 60041:1991) would not allow the verification of guarantees given for the prototype machine. A transposition method taking into account the model and prototype wall surface roughness for the performance conversion on pump-turbines, Francis turbines, and axial machines is described in IEC 62097. This method requires model and prototype surface roughness data and is takes into account the shift in nED, QED and PED factors for determining the transposition of efficiency between model and prototype. However, in the case of Francis machines with semispiral casing and axial machines, the transposition method has not been fully validated due to a lack of data. In addition, IEC 62097 does not apply to storage pumps, Pelton turbines, and Dériaz. Therefore, for these and otherwise specifically agreed upon cases where hydraulically smooth flow conditions are assumed on the model and the prototype, the transposition formula and procedure given in Annex D and Annex I can be applied. Applications and limitations of both this document and IEC 62097 transposition methods are discussed in Annex E. The method for performance conversion from model to prototype needs to be clearly defined in the main hydraulic performance contract.

IEC 62364:2019 is available as IEC 62364:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62364:2019 gives guidelines for: a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites; b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site; c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems; d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings; e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers; f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life. It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues. It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation. Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydro-abrasive erosion resistant coatings can also be damaged locally by impact of large solids. It is beyond the scope of this document to address these issues. This document focuses mainly on hydroelectric powerplant equipment. Certain portions can also be applicable to other hydraulic machines. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the formula for TBO in Pelton reference model has been modified; b) the formula for calculating sampling interval has been modified; c) the chapter in hydro-abrasive erosion resistant coatings has been substantially modified; d) the annex with test data for hydro-abrasive erosion resistant materials has been removed; e) a simplified hydro-abrasive erosion evaluation has been added.

This document focuses on recommended condition monitoring techniques for detecting and diagnosing developing machine faults associated with the most common potential failure modes for hydro unit components. It is intended to improve the reliability of implementing an effective condition monitoring approach for hydroelectric generating units (hydro units). It is also intended to help create a mutual understanding of the criteria for successful hydro unit condition monitoring and to foster cooperation between the various hydropower stakeholders. This document is intended for end-users, contractors, consultants, service providers, machine manufacturers and instrument suppliers. This document is machine-specific and is focused on the generator, shaft/bearing assembly, runner (and impeller for pumped storage applications), penstock (including the main inlet valve), spiral case and the upper draft tube of hydro units. It is primarily intended for medium to large sized hydro units with more than 50 MVA installed capacity, but it is equally valid for smaller units in many cases. It is applicable to various types of turbines such as Francis, Kaplan, Pelton, Bulb and other types. Generic auxiliary systems such as for lubrication and cooling are outside the scope, with the exception of some monitoring techniques that are related to condition monitoring of major systems covered by this document, such as oil analysis. Transmission systems, civil works and the foundation are outside the scope. This document covers online (permanently installed) and portable instrument condition monitoring and diagnostic techniques for operational hydro units. Offline machine testing, i.e. that which is only done during shutdown, although very important, is not part of the scope of this document. Nor is one-time acceptance and performance testing within the scope. The condition monitoring techniques presented in this document cover a wide range of continuous and interval-based monitoring techniques under generalized conditions for a wide range of applications. Therefore, the actual monitoring approach required for a specific application can be different than that which is recommended in this generalized document.

This document applies to laboratory models of any type of impulse or reaction hydraulic turbine,
storage pump or pump-turbine.
This document applies to models of prototype machines either with unit power greater than
5 MW or with reference diameter greater than 3 m. Full application of the procedures herein
prescribed is not generally justified for machines with smaller power and size. Nevertheless,
this document may be used for such machines by agreement between the purchaser and the
supplier.
In this document, the term "turbine" includes a pump-turbine operating as a turbine and the
term "pump" includes a pump-turbine operating as a pump.
This document excludes all matters of purely commercial interest, except those inextricably
bound up with the conduct of the tests.
This document is concerned with neither the structural details of the machines nor the
mechanical properties of their components, so long as these do not affect model performance
or the relationship between model and prototype performances.
This document covers the arrangements for model acceptance tests to be performed on
hydraulic turbines, storage pumps and pump-turbines to determine if the main hydraulic
performance contract guarantees (see 4.2) have been satisfied.
It contains the rules governing test conduct and prescribes measures to be taken if any phase
of the tests is disputed.
The main objectives of this document are:
– to define the terms and quantities used;
– to specify methods of testing and of measuring the quantities involved, in order to ascertain
the hydraulic performance of the model;
– to specify the methods of computation of results and of comparison with guarantees;
– to determine if the contract guarantees that fall within the scope of this document have been
fulfilled;
– to define the extent, content and structure of the final report.
The guarantees can be given in one of the following ways:
– guarantees for prototype hydraulic performance, computed from model test results
considering scale effects;
– guarantees for model hydraulic performance.
Moreover, additional performance data (see 4.4) can be needed for the design or the operation
of the prototype of the hydraulic machine. Contrary to the requirements of Clauses 4 to 6 related
to main hydraulic performance, the information of these additional data given in Clause 7 is
considered only as recommendation or guidance to the user (see 7.1).
It is particularly recommended that model acceptance tests be performed if the expected field
conditions for acceptance tests (see IEC 60041:1991) would not allow the verification of
guarantees given for the prototype machine.
A transposition method taking into account the model and prototype wall surface roughness for
the performance conversion on pump-turbines, Francis turbines, and axial machines is
described in IEC 62097. This method requires model and prototype surface roughness data and
is takes into account the shift in nED, QED and PED factors for determining the transposition of
efficiency between model and prototype. However, in the case of Francis machines with semispiral
casing and axial machines, the transposition method has not been fully validated due to
a lack of data. In addition, IEC 62097 does not apply to storage pumps, Pelton turbines, and
Dériaz. Therefore, for these and otherwise specifically agreed upon cases where hydraulically
smooth flow conditions are assumed on the model and the prototype, the transposition formula
and procedure given in Annex D and Annex I can be applied. Applications and limitations of
both this document and IEC 62097 transposition methods are discussed in Annex E.
The method for performance conversion from model to prototype needs to be clearly defined in
the main hydraulic performance contract.

This document gives guidelines for:
a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites;
b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site;
c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems;
d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings;
e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers;
f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life.
It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues.
It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation.
Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydroabrasive erosion resistant coatings can also be damaged locally by impact of large solids. It isbeyond the scope of this document  to address these issues.
This document focuses mainly on hydroelectric powerplant equipment. Certain portions can
also be applicable to other hydraulic machines.
