  • IEC 61196-10:2014(E) applies to semi-rigid coaxial communication cables with polytetrafluoroethylene (PTFE) dielectric and tubular outer conductor. These cables are intended for use in microwave and wireless equipments or other signal transmission equipments or units at frequencies above(...)
  • IEC 61196-10-1:2014(E) applies to coaxial communication cables described in IEC 61196-10. It specifies the requirements for semi-rigid radio frequency and coaxial cables with solid dielectric and semi-airspace dielectric. These cables are intended for use in microwave and wireless equipment or(...)
  • Lays down requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates, as defined in IEC 60721-2-1. Determines the electrical and thermal characteristics of the module and shows, as far as(...)
  • Applies to equipment and data related to the process of teleradiotherapy, including patient image data used in relation with radiotherapy treatment planning systems, radiotherapy simulators, isocentric gamma beam therapy equipment, isocentric medical electron accelerators, and non-isocentric(...)
  • Applies to equipment for temporary earthing or earthing and short-circuiting of electrically isolated parts of a.c. installations, the disconnection of which has been verified, for the protection of workers while work is in progress using lance(s) as the earthing or earthing and(...)
  • Defines the intended criteria for the choice, conception and use of equipment for the measurement of the response time of resistance temperature detectors (RTD) which are used in the safety and control systems of nuclear reactors. Describes the techniques which can be used for the in situ(...)
  • Specifies the performance and the functional characteristics of the electrical supply systems required for the instrumentation and control (I&C) systems important to safety of a nuclear power plant. Gives also guidance on the possible use of these supplies for other I&C systems.
  • IEC 61226:2009 establishes a method of classification of the information and command functions for nuclear power plants, and the instrumentation and control systems and equipment that provide those functions, into categories that designate the importance to safety of the function.
  • IEC 61227:2008 identifies the Human-Machine Interface (HMI) requirements for discrete controls, multiplexed conventional systems, and soft control systems. To be used with IEC 60964 and IEC 61772. Is intended for application to the design of new main control rooms in nuclear power plants(...)
  • Applies to rigid insulating covers for live working on a.c. installations, including those described in IEC 60743.
  • applicable to portable equipment, with or without matching connection points, for temporary earthing or earthing and short-circuiting of electrically isolated or de-energized a.c. and d.c. installations, distribution and transmission networks, whether they are overhead or underground or of low(...)
  • Describes the test method for determination of hydrolytic stability of moulded thermosets made of room temperature or oven-curing reaction resins when subjected to simultaneous influence of water and high temperature.
  • Applies to insulating hollow tubes made of synthetic materials and intended for tools and equipment for work on systems operating at voltages above 1 kV.
  • Applies to saddles, stick clamps and their accessories, used for live working. The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use.
  • This standard is applicable to portable voltage detectors with or without a built-in power source to be used on electrical systems for voltages of 1 kV to 36 kV a.c., and frequencies from 15 Hz to 60 Hz. This part applies only to resistive voltage detectors used in contact with the part to be(...)
  • Applicable to hand-held two-pole voltage detectors with its accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: - for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or - for d.c. voltages(...)
  • This standard is applicable to voltage detecting systems that are single-pole and are capacitively-coupled to live parts. They are used to detect the presence or absence of operating voltage on a.c. electrical systems for voltages from 1 kV to 52 kV, and for frequencies from 16 2/3 Hz to 60(...)
  • Defines the requirements for instrumentation needed to detect leakage from reactor coolant systems of light water nuclear reactors. Methods of leak detection are described, and characteristics of different methods of detection and of differentiating between allowable and abnormal leakages are given.
  • Applies to instruments for measurement of A-frequency- weighted sound exposure resulting from steady, intermittent, fluctuating, irregular, or impulsive sound. Specifies acoustical and electrical performance requirements for personal sound exposure meters of one accuracy grade.
  • Relates to assemblies that are used to monitor clothing for radioactive contamination. Applies to monitoring that is performed after the clothing has been washed and prior to re-use to determine its acceptability for re-use.
