This document specifies the conditions for conducting axial, constant-amplitude, force-controlled, fatigue tests at ambient, elevated, and low temperature on metallic specimens, without deliberately introduced stress concentrations. The object of testing while employing this document is to provide fatigue information, such as the relation between applied stress and number of cycles to failure for a given material condition, such as microstructure, at various stress ratios. While the form, preparation and testing of specimens of circular and rectangular cross-section are described, component testing and other specialized forms of testing are not included in this document. NOTE 1 Fatigue tests on notched specimens are not covered by this document since the shape and size of notched test pieces have not been standardized. However, fatigue-test procedures described in this document can be applied to fatigue tests of such notched specimens. NOTE 2 Throughout this document, the engineering stress is employed. Engineering stress is equal to the axially applied force divided by the cross-sectional area of the test specimen, S = Force/Area, [MPa], at the test temperature.

This document specifies an accelerated method for the determination of wet-scrub resistance. The determination of cleanability is not covered in the scope of this document. NOTE The ability of coatings to withstand wear caused by repeated cleaning operations is an important consideration both from a practical point of view and when comparing and rating such coatings. Since wet-scrub resistance depends not only on the quality of a coating but also on the substrate, the method of application, the drying conditions and other factors, the results obtained are not directly transferable to actual practice. In this document, the evaluation of the coating is based on a defined substrate, a fixed application method, specified drying conditions and a defined method of wet scrubbing.

It deals with steady-state and short-time direct current (as e.g. encountered in high-power DC testing), steady-state and short-time alternating current (as e.g. encountered in high-power AC testing), and impulse-current. In general, currents above 100 A are considered in this International Standard, although currents less than this can occur in tests.
This standard:
• defines the terms used;
• defines parameters and their tolerances;
• describes methods to estimate uncertainties of high-current measurements;
• states the requirements applicable to a complete measuring system;
• describes the methods for approving a measuring system and checking its components;
• describes the procedure by which the user shows that a measuring system meets the requirements of this document, including limits set for uncertainty of measurement.

This document applies to all high-voltage direct current (HVDC) converter stations with linecommutated converters (LCC) as well with voltage-sourced converters (VSC) used for power exchange (power transmission or back-to-back installation) in utility systems. For linecommutated converters (LCC), this document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters.
Where VSC is referred to in this document, it is assumed to be of the MMC-type or similar, with very low harmonic generation. It is important to treat other types of VSC as appropriate.
In some applications, synchronous compensators, static var compensators (SVC), or static synchronous compensator (STATCOM) are connected to the AC bus of the HVDC converter station. The loss determination procedures for such equipment are not included in this document.
This document presents a set of standard procedures for determining the total losses of an HVDC converter station, except for VSC valves which are covered by the IEC 62751 series.
The procedures cover all parts, except as noted above, and address no-load operation and operating losses together with their methods of calculation which use, wherever possible, measured parameters.
Converter station designs employing novel components or circuit configurations compared to the typical design assumed in this document, or designs equipped with unusual auxiliary circuits that can affect the losses, are assessed on their own merits.

This document specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This document covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source.
Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and could be suitable for energizing other essential safety equipment, for example:
- electric circuits of automatic fire extinguishing installations;
- paging systems and signalling safety installations;
- smoke extraction equipment;
- carbon monoxide warning systems;
- special safety installations related to specific buildings, e.g. high-risk areas.
The power supply of CPS systems is expected to be dedicated only to the essential safety equipment, and not for other type of loads such as general purpose IT or industrial systems etc.
Combinations of the aforementioned safety equipment types can be used together on the same central safety power supply system providing the availability for safety equipment loads is not impaired. A fault occurring in a circuit is expected to not cause the interruption in any other circuit used to supply essential safety equipment.
Schematic representations of typical central safety power supply equipment are depicted in Clause 4.
Power supply systems for fire alarm equipment that are covered by EN 54 (series) are excluded.

This document specifies the methods, parameter sets and models to develop and utilize a data package for a part created using AM technologies (AM part). This document is applicable to the information requirements associated with workflow of the fabrication of an AM part, from design to acceptance. Peripheral information related to entities such as organization, facility, operator, security, and others is addressed for sake of completeness; but is not the focus of this document and can be defined elsewhere. This document provides the means to develop an organizational or application-specific data package for the communication between and amongst the designer, the manufacturer, and all acceptance authorities, among other potential stakeholders.
This document does not impose a plan of execution to produce an AM part, though a digital thread is provided to establish a referenceable information workflow.
The requirements set forth in this document are based on the fabrication of a part using the PBF-LB/M (powder bed fusion-laser based/metal) process. While specific details directly relate to PBF-LB/M, generalized workflow requirements can be related to any AM process.

This document specifies procedures for the evaluation of basic performance parameters of the radiographic film digitisation process, such as spatial resolution and spatial linearity, density range, density contrast sensitivity and characteristic transfer curve, which are applied in ISO 14096-2. These procedures can be integrated into the system software, and together with a standard reference film (see Annex B), used for quality control of the digitisation process. This reference film provides a series of test targets for performance evaluation. The test targets are suitable for evaluating a digitisation system with a basic spatial resolution down to 10 µm, a density contrast sensitivity down to 0,02 optical density, a density range of 0,5 to 4,5 and a film size capacity of (350 × 430) mm2.
This document does not address signal processing and display of the digitised data.

IEC 62541-9:2026 specifies the representation of Alarms and Conditions in the OPC Unified Architecture. Included is the Information Model representation of Alarms and Conditions in the OPC UA address space. Other aspects of alarm systems like alarm philosophy, life cycle, alarm response times, alarm types and many other details are captured in standards such as IEC 62682 and ISA 18.2. The Alarms and Conditions Information Model in this document, is designed in accordance with IEC 62682 and ISA 18.2. Annex C specifies a recommended mapping between OPC Classic Alarm & Events (A&E) servers to the model described in this document. Annex A describes recommended localized names for Alarm states. Annex B describes examples (e.g. Event sequences, Alarm areas in AddressSpace). This fourth edition cancels and replaces the third edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of "Comment" parameter to Alarm shelving methods;
b) addition of method that allows a client to get the members of a group, since it is possible that the AddressSpace does not expose instances of alarms;
c) addition of deadband properties for all limits in the limit AlarmType (from which all other types described in this issue are derived);
d) addition of text explaining the disabling of alarms is no longer supported in ISA 18.2 and that it is maintained in this document for backward compatibility, but that it is recommended that Alarm not be disabled;
e) addition of optional severities for limit alarms;
f) addition of new AlarmState variable type that can be used to collect alarm information for displays on graphics;
g) addition of SupportsFilterRetain property to improve Client filtering;
h) removal of ConditionSubClassId and ConditionSubClassNames from the conditiontype definition since they are now defined in BaseEventType.
