Electroacoustics - Hearing aids - Part 0: Measurement of the performance characteristics of hearing ...
IEC 60118-0:2022 gives recommendations for the measurement of the performance characteristics of air conduction hearing aids measured with an acoustic coupler or occluded ear simulator.
This document is applicable to the measurement and evaluation of the electroacoustical characteristics of hearing aids, for example for type testing and manufacturer data sheets.
This document is also applicable…
Generic smart grid requirements - Part 1: Specific application of the use case methodology for defin...
IEC SRD 62913-1:2022 (E) describes a common approach for IEC technical committees to define generic smart grid requirements for further standardization work. It uses as input the use case methodology defined as part of the IEC 62559 series, and provides a more detailed methodology for describing use cases and extracting requirements from these use cases. This will achieve a consistent and…
Personal safety — Personal protective equipment — Guidelines on compatibility testing of PPE
This document describes compatibility for ensembles of personal protective equipment (PPE) to be used by personnel where operating situations and processes require more than one piece of PPE. Where there is more than one risk to health and safety, it is necessary to wear or use more than one item of PPE at the same time. Such equipment should be compatible and continue to be effective to minimise…
Radiators and convectors — Methods and rating for determining the heat output
This document defines procedures for determining the standard thermal outputs and other characteristics of radiators and convectors installed in a permanent manner in construction works, fed with water or steam at temperatures below 120 °C, supplied by a remote energy source.
This document specifies the laboratory arrangements and testing methods to be adopted, the admissible tolerances, the…
Communication networks and systems for power utility automation - Part 1-2: Guideline on extending I...
IEC TS 61850-1-2:2020+AMD1:2022, which is a technical specification, is intended for any users but primarily for standardization bodies that are considering using IEC 61850 as a base standard within the scope of their work and are willing to extend it as allowed by the IEC 61850 standards. This document identifies the required steps and high-level requirements in achieving such extensions of IEC…
Paints and varnishes — Determination of resistance to cyclic corrosion conditions — Part 3: Testing ...
This document specifies a method based on a cyclic corrosion test for testing the corrosion protection of automobiles using coating systems on aluminium, steel or galvanized steel.
The test method uses corrosive conditions (temperature and humidity ramps and salt spray) to create realistic corrosion patterns. These corrosion patterns are typical for automobiles, and they are comparable in the…
This document establishes the basic principles and methods for preparing and compiling terminologies both inside and outside the framework of standardization. It describes the links between objects, concepts, definitions and designations. It also establishes general principles for the formation of terms and proper names and the writing of definitions.
This document is applicable to terminology…
