    Definition
  • IEC 61400-12-2:2013 specifies a procedure for verifying the power performance characteristics of a single electricity-producing, horizontal axis wind turbine, which is not considered to be a small wind turbine per IEC 61400-2.
  • IEC 61400-21:2008 covers the definition and specification of the quantities to be determined for characterizing the power quality of a grid connected wind turbine; measurement procedures for quantifying the characteristics; and procedures for assessing compliance with power quality(...)
  • IEC 61400-22:2010 defines rules and procedures for a certification system for wind turbines (WT) that comprises both type certification and certification of wind turbine projects installed on land or off-shore.
  • IEC 61400-24:2010(E) applies to lightning protection of wind turbine generators and wind power systems. Defines the lightning environment for wind turbines and application of the environment for risk assessment for the wind turbine. Defines requirements for protection of blades, other(...)
  • Gives an overall description of the principles and models used in the IEC 61400-25 series of standards. The IEC 61400-25 series deals with communications between wind power plant components such as wind turbines and actors such as SCADA Systems. It is designed for a communication environment(...)
  • Specifies the information model of devices and functions related to wind power plant applications. Specifies in particular the compatible logical node names, and data names for communication between wind power plant components, including the relationship between logical devices, logical nodes(...)
  • Specifies an abstract communication service interface describing the information exchange between a client and a server for: data access and retrieval, device control, event reporting and logging, publisher/subscriber, self-description of devices (device data dictionary), data typing and(...)
  • IEC 61400-25-4:2008(E) specifies the specific mappings to protocol stacks encoding the messages required for the information exchange between a client and a remote server for data access and retrieval, device control, event reporting and logging, publisher/subscriber, self-description of(...)
  • Specifies standard techniques for testing of conformance of implementations, as well as specific measurement techniques to be applied when declaring performance parameters.
  • IEC 61400-25-6:2010(E) specifies the information models related to condition monitoring for wind power plants and the information exchange of data values related to these models.
  • IEC 61427-1:2013 is part of a series which gives general information relating to the requirements for the secondary batteries used in photovoltaic energy systems (PVES) and to the typical methods of test used for the verification of battery performances.
  • IEC 61435:2013(E) is applicable to high-purity germanium crystals used for radiation detectors for gamma-rays and X-rays. Such germanium is monocrystalline and has a net concentration of fewer than 1011 electrically active impurity centers per cm3. This International Standard specifies(...)
  • Specifies methods of calibration and routine tests of scintillation detector systems for the measurement of gamma-ray energies and emission rates of radionuclides and the assay of radioactivity. Is applicable to scintillation detector systems based on inorganic scintillators for photon measurements.
  • Applies to in-core neutron detectors and instrumentation, which are designed for purposes important to safety, such as protection, control and information. Gives requirements, recommendations and guidance on selection of the type and characteristics of self powered neutron detectors used in(...)
  • Describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and/or workers at different electric potentials.
  • Gives the minimum requirements relative to specification, manufacture, selection, application and maintenance of tools, devices and equipment for live working. It provides the type of information which is useful to skilled persons in order to make the use of tools, devices and equipment safer.
  • Is applicable to fully insulating spliced or hook ladders with extension or having a combination of insulating and conductive sections and used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. This standard concerns only(...)
  • Is applicable to flexible insulating covers (line hoses) for the protection of workers from accidental contact with live or earthed electrical conductors and for the avoidance of short circuits during live working.
  • Is applicable to portable phase comparators with or without a built-in power source to be used on electrical systems for voltages from 1 kV to 36 kV a.c. and frequencies from 50 Hz to 60 Hz. This standard is applicable to two-pole phase comparators having a connecting lead between them,(...)
  • Specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials.
