  • IEC 60951-3:2009 provides general guidance on the design principles and performance criteria for equipment for continuous high range area gamma monitoring in nuclear power plants for accident and post-accident conditions.
  • IEC 60951-4:2009 provides general guidance on the design principles and performance criteria for equipment for continuous in-line or on-line monitoring of radioactivity in process stream in nuclear power plants for accident and post-accident conditions.
  • Specifies very accurate testing of steam turbines to obtain the level of performance with minimum measuring uncertainty. Defines uniform rules for preparing and carrying out an evaluation of the acceptance tests.
  • Provides for acceptance tests of steam turbines of various types and capacities with appropriate measuring uncertainty. Only the relevant portion of these rules will apply to any individual case. The resulting measuring uncertainty of the test result is determined by calculating methods(...)
  • This part of IEC 60953, also called "retrofit code" (RC), establishes a supplementary retrofit code for thermal verification tests of retrofitted steam turbines.
  • Considers the functional design criteria for a Safety Parameter Display System (SPDS) giving concise information to aid operating personnel, particularly in abnormal conditions.
  • IEC 60964:2009 provides functional design requirements to be used in the design of the main control room of a nuclear power plant to meet operational and safety requirements. Also provides functional interface requirements which relate to control room staffing, operating procedures, and the(...)
  • IEC 60965:2009 establishes requirements for the supplementary control points provided to enable the operating staff of nuclear power plants to shut down the reactor and maintain the plant in a safe shut-down state in the event that control of the safety functions can no longer be exercised(...)
  • This standard is applicable to equipment for arc welding and allied processes, including power sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilizing devices.
  • Applies to medical electron accelerators when used, for therapy purposes, in human medical practice. This standard applies to medical electron accelerators which deliver a radiation beam of either X-radiation or electron radiation with nominal energies in the range 1 MeV to 50 MeV at maximum(...)
  • Applies to insulating sleeves for the protection of workers from accidental contact with live electrical conductors, apparatus or circuits.
  • IEC 60987:2007+A1:2013 Is applicable to computer-system hardware for systems of Class 1 and 2 (as defined by IEC 61513) in nuclear power plants. This new edition reflects recent developments in computer system hardware design, the use of pre-developed hardware and changes in terminology.
  • IEC 60988:2009 is applicable to on-site systems used for continuous monitoring of structure-borne sound measured at the reactor coolant pressure boundary of light water reactors for the purpose of detecting loose parts.
  • IEC 61000-3-2:2014 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions. It is applicable to electrical and electronic(...)
  • The object of this part of IEC 61000 is to give applicability assistance to the technical committees of IEC or other bodies, users and manufacturers of electrical and electronic equipment on EMC standards within the IEC 61000-4 series on testing and measurement techniques and to provide(...)
  • IEC 61000-4-2:2008 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and from personnel to adjacent objects. It additionally defines ranges of test levels which relate to different(...)
  • IEC 61000-4-3:2006+A1:2007+A2:2010 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures. The object of this standard is to establish a common reference for evaluating(...)
  • IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It has the status of a basic EMC publication in accordance with IEC Guide 107. It gives immunity requirements and test procedures related to electrical fast(...)
  • IEC 61000-4-5:2005 relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and(...)
  • IEC 61000-4-6:2013 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. Equipment not having at least one conducting wire and/or(...)
