Cavitation pitting evaluation in hydraulic turbines, storage pumps and pump-turbines

Cavitation pitting evaluation in hydraulic turbines, storage pumps and pump-turbines

Serves as a basis for the formulation of guarantees applying to cavitation pitting, and also for the measurement and evaluation of the amount of cavitation pitting on certain specified parts of a given machine.

Evaluation de l'érosion de cavitation dans les turbines, les pompes d'accumulation et les pompes-turbines hydrauliques

Sert de base à la formulation des garanties s'appliquant à l'érosion de cavitation et, d'autre part, à la mesure et à l'évaluation de l'extension de l'érosion de cavitation sur certaines parties spécifiées d'une machine donnée.

Hydraulic machines - Guide for dealing with hydro-abrasive erosion in Kaplan, Francis, and Pelton turbines (IEC 62364:2019)
EN IEC 62364:2019

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.

Thermal insulation for buildings - Reflective insulation products - Determination of thermal performance (ISO 22097:2023)
EN ISO 22097:2023

This document describes a set of procedures for using existing standardized CEN or ISO test and calculation methods to determine the thermal performance of reflective insulation products. This document supports and does not replace existing CEN or ISO test methods.
This document applies to any thermal insulation product that derives a proportion of its claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s). It does not replace the existing procedures for the determination of the thermal performance of products already covered by an existing harmonized product standard where the declared value of these products does not specifically include any claims attributable to the emissivity of the facing. It does not, and cannot, give an in-use or design value of thermal performance, but provides standardized information from which these can be determined.

Gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW - Part 1: Terms and definitions
EN 12309-1:2023

1.1   Scope of EN 12309
Appliances covered by this European Standard include one or a combination of the following:
-   gas-fired sorption chiller;
-   gas-fired sorption chiller/heater;
-   gas-fired sorption heat pump.
This European Standard applies to appliances designed to be used for space heating or cooling or refrigeration with or without heat recovery.
This European Standard applies to appliances having flue gas systems of type B and C (according to CEN/TR 1749) and to appliances designed for outdoor installations. EN 12309 does not apply to air conditioners, it only applies to appliances having:
-   integral burners under the control of fully automatic burner control systems,
-   closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated,
-   mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in prEN 12309 1:2012).
In the case of packaged units (consisting of several parts), this standard applies only to those designed and supplied as a complete package.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
All the symbols given in this text should be used regardless of the language used.
1.2   Scope of this Part 1 of EN 12309
This part of this European Standard specifies the terms and definitions for gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW.

Glass-reinforced thermosetting plastics (GRP) pipes - Determination of the ring creep properties under wet or dry conditions (ISO 10468:2023)
EN ISO 10468:2023

This document specifies methods for determining the ring creep properties for glass-reinforced thermosetting plastics (GRP) pipes. Properties include the creep factor and the long-term specific creep stiffness. Testing is performed under either wet (total immersion in water) or dry conditions.
Dry creep testing is typically performed for the assessment and control of raw material consistency. Wet creep testing is typically undertaken to determine the long-term creep performance in simulated use conditions.
