This part of IEC 61850 specifies the logical node classes for use in the domain of hydroelectric power stations, steam and gas turbines.
This IEC61850 domain information model standard utilizes the existing Logical Node (LN) classes defined in IEC 61850-7-4, Basic communication structure – Compatible logical node classes and data object classes where possible, while defining new and extended domain specific LN classes to provide the necessary data objects for application to functions and systems in the domain of hydroelectric power stations, steam and gas turbines. The domain information model includes the interface towards a central operator centre’s control functions.
The Scope of this document, related to steam and gas turbine specifics, is limited to overall control functions and generator and turbine control functions. For hydroelectric power, the scope includes the entire power station automation system.
Edition 3 is intended to form a basis for extensions in local implementations. Such extensions may be defined in profiles. Many of the Logical Nodes defined in this document are designed to be suitable for use in domains beyond the scope of hydro power plants and steam and gas turbines. A suggested structure of the Logical Nodes into packages for integration with other domains is provided in Annex G (informative), Migration of this document to the future edition of IEC 61850.

IEC 60953-4:2026 is intended to establish a Supplementary Standard for routine test of steam turbines. The rules given in this document follow the guidance given in IEC 60953-0, but contain amendments and supplements regarding the analysis and supervision of relative performance by routine testing of steam turbine.
General principles for the preparation, performance evaluation, trends of performance parameters and the determination of the measurement uncertainty of periodic routine tests are given in this document.
This document is applicable to routine testing covering a wide range of accuracy on steam turbines of every type, rating and application, operating with superheated or saturated steam.
This document is not intended for application in acceptance tests of new units or retrofits and its application for such is strongly not recommended.
The purpose of this document is to cover the existing steam turbine components which influence the efficiency of the power plant. This document helps the parties determine the most appropriate parameters that characterize the relative performance change and that could be used as long-term performance monitoring and analysis.

This document applies to hearing aid fitting management (HAFM) services offered by hearing aid professionals (HAP) when providing benefit for their clients. The provision of hearing aids relies on the knowledge and practices of a hearing aid professional, to ensure the proper fitting and adequate service in the interest of the client with hearing loss. This document specifies general processes of HAFM from the client profile to the follow-up through administering, organising and controlling hearing aid fitting through all stages. It also specifies important preconditions such as education, facilities and systems that are required to ensure proper services. The focus of this document is the services offered to the majority of adult clients with hearing impairment. It is recognized that certain populations with hearing loss such as children, persons with other disabilities or persons with implantable devices can require services outside the scope of this document. This document generally applies to air conduction hearing aids and for the most part also to bone conduction devices. Hearing loss can be a consequence of serious medical conditions. Hearing aid professionals are not in a position to diagnose or treat such conditions. When assisting clients seeking hearing rehabilitation without prior medical examination, hearing aid professionals are expected to be observant of symptoms of such conditions and refer to proper medical care. Further to the main body of the document, which specifies the HAFM requirements and processes, several informative annexes are provided. Appropriate education of hearing aid professionals is vital for exercising HAFM. Annex A defines the competencies required for the HAFM processes. Annex B offers a recommended curriculum for the education of hearing aid professionals. Annex C is an example of an appropriate fitting room. Annex D gives guidance on the referral of clients for medical or other specialist examination and treatment. Annex E is a recommendation for important information to be exchanged with the client during the process of HAFM. Annex F is a comprehensive terminology list offering definitions of the most current terms related to HAFM. It is the intention that these annexes be helpful to those who wish to deliver HAFM of the highest quality.

This document specifies the data exchange requirements between related systems within the smart city for electric vehicle (EV)-based demand response (DR) services utilizing nomadic devices as follows: EV-based DR service for demand reduction, called “demand response” during the shortage of reserve on electric grid or in response to a fine dust warning issued according to an air quality forecast; EV-based DR for demand increase, called “reverse demand response”, instead of curtailment during excess electricity generation by renewable energy sources such as the sun and wind. This document defines the requirements of main actors such as the EV, nomadic device, smart city cloud, charging station and service provider to support EV-based DR services. This document also defines the data set and data processing procedure requirements for EV-based DR services.

The application of LCI results, including life cycle impact assessment (LCIA), is outside the scope of this document.

This document specifies the mounting dimensions required for interchangeability of rod-end spherical eyes of pneumatic cylinders. The rod-end spherical eyes have been designed specifically for the use with 1 000 kPa [10 bar1)] series cylinders manufactured in accordance with ISO 6432 and ISO 15552, but this does not limit their application. The spherical bearing end eyes are used on piston rods of pneumatic cylinders for mechanically transmitting the cylinder force under oscillatory rotational and tilting movements. The design of the rod-end spherical eyes is based on the maximum forces resulting from the specified internal diameter of the cylinders and pressure according to ISO 6432, ISO 15552 and ISO 21287. 1)1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

These fuses are normally intended to be mounted or replaced only by appropriately skilled persons using specialized equipment. This document applies in addition to the requirements of IEC 60127-1. The objectives of this part of IEC 60127 are as given in IEC 60127-1, with the additional requirement of a degree of non-interchangeability. This fourth edition cancels and replaces the third edition published in 2005, Amendment 1:2008 and Amendment 2:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) align to IEC 60127-1:2023, third edition; b) enhance the rated current of UMFs to 100A and provide the corresponding maximum voltage drop and maximum sustained dissipation; c) modify the figures; d) update the normative references to the latest version.
