  • Term
    Definition
  • Specifies quantitative test methods for determining the heat release from the combustion of insulating liquids of electrotechnical products when exposed to a defined heat flux with spark ignition.
  • Provides a summary of test methods that are used to determine the surface spread of flame of electrotechnical products or materials from which they are formed. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance(...)
  • Describes a test method used to determine the characteristic heat flux for ignition (CHFI) from a non-contacting flame source for materials used in electrotechnical products and sub-assemblies. It provides a relationship between ignition time and incident heat flux.
  • Describes a small-scale laboratory procedure for determining the comparative burning characteristics of tubular polymeric materials. A flame is applied to test specimens held in a vertical position, supported by a wire or mandrel.
  • Presents a general characterization of small-scale test flames and associated confirmatory tests based on copper block calorimetry, and defines theoretical modelling for the associated dynamics. Guidance is presented for the selection of critical parameters in confirmatory test designs.
  • This technical report defines how protective devices for High Altitude Nuclear Electromagnetic Pulse (HEMP) protection of civilian systems are specified. Performance requirements will be given in future IEC standards. This technical report is intended to be used for the harmonization of(...)
  • IEC/TS 61000-5-9:2009(E) is to present a methodology to assess the impact of High-altitude Electromagnetic Pulse (HEMP) and High Power Electromagnetic (HPEM) environments on electronic systems. In this context a system refers to a collection of sub-systems, equipment and components brought(...)
  • Provides guidance on the use of conventional touch voltage limits with reference to thresholds given in IEC 60479-5. Consideration is given to different physiological effects, environmental conditions, contact conditions, etc. This specification only discusses voltages for sinusoidal a.c. at(...)
  • Describes the importance of the chemical characteristics of steam supplied to steam turbines and the need to prevent corrosion and deposition in steam space, in order to minimize the risk of turbine corrosion failures or loss of efficiency or output. Is applicable to turbines of all electrical(...)
  • Acts as a guide for carrying out measurements used for verification of codes and for direct determination of the structural loading. Focuses mainly on large electricity generating horizontal axis wind turbines.
  • Gives guidelines for declaring the apparent sound power level and tonality of a batch of wind turbines. Is to be used in conjunction with IEC 61400-11 which gives measurement procedures for apparent sound power level and tonality.
  • Is a technical specification providing guidelines for the full-scale structural testing of wind turbine blades and for the interpretation or evaluation of results, as a possible part of a design verification of the integrity of the blade. Includes static strength tests, fatigue tests, and(...)
  • IEC 61400-26-1:2011(E) defines generic information categories to which fractions of time can be assigned for a wind turbine generating system (WTGS) considering internal and external conditions based on fraction of time and specifying the following: generic information categories of a WTGS(...)
  • Provides an informative guide on care, maintenance and in-service testing requirements of aerial devices with insulating booms used for live working.
  • Provides terms, definitions and symbols from national and international solar photovoltaic standards and relevant documents used within the field of solar photovoltaic (PV) energy systems.
  • Contains the glossary of specific terms and definitions used in the context of Substation Automation Systems which are standardized in the various parts of the IEC 61850 series.
  • Provides a glossary for the volume of work produced as part of the IEC 61970 series of publications. Supplies terms and abbreviations that are either specific to the series, or that require explanation because of the way that they are used.
  • Specifies the framework for the specification of Component Interface Specifications (CIS) for Energy Management System Application Program Interfaces. A CIS specifies the interfaces that a component (or application) should implement to be able to exchange information with other components (or(...)
  • Specifies requirements for the selection, positioning, configuration and commissioning of protective equipment to detect the presence of persons in order to protect those persons from dangerous part(s) of machinery in industrial applications.
  • Describes a 3 layer data exchange architecture used for communication with large industrial and commercial customer's metering equipment (remote reading for billing purpose). The public switched telephone network (PSTN) is used as a communication medium for this data exchange.
