  • Provides guidance for the design of in-core instrumentation for neutron fluence rate measurements in thermal neutron reactors designed for power production. Applies to on-line in-core neutron detectors, together with associated components and instrumentation, designed for purposes important to(...)
  • Establishes mandatory requirements and gives a list of characteristics of equipment for grading and sorting radioactive ores in containers at minehead and in opencast workings.
  • IEC 60601-1-2:2014 applies to the basic safety and essential performance of Medical Equipment (ME) equipment and ME systems in the presence of electromagnetic disturbances and to electromagnetic disturbances emitted by me equipment and me systems. 
  • Applies to X-ray equipment and to subassemblies of such equipment, where radiological images of a human patient are used for diagnosis, planning or guidance of medical procedures. The object of this collateral standard is to establish general requirements for protection against X-radiation in(...)
  • The objective of this collateral standard is to improve the environmental impact for the entire range of medical electrical equipment, taking into account all stages of the product life cycle:
  • Medical electrical equipment – Part 1-12: General requirements for basic safety and essential performance – Collateral Standard: Requirements for medical electrical equipment and medical electrical systems intended for use in the emergency medical services environment.
  • IEC 60601-2-1:2009+A1:2014 applies to the basic safety and essential performance of electron accelerators in the range 1 MeV to 50 MeV, used for treatment of patients. This particular standard establishes requirements to be complied with by manufacturers in the design and construction of(...)
  • IEC 60601-2-64:2014 applies to the basic safety and essential performance of Light Ion Beam Medical Electrical equipment, hereafter referred to as ME equipment, used for treatment of patients.
  • IEC 60601-2-68:2014 applies to the basic safety and essential performance of X-ray based image-guided radiotherapy (IGRT) equipment for use with External Beam Equipment (EBE). This particular standard covers safety aspects of kilovoltage and megavoltage X-ray imaging devices in a known(...)
  • This standard serves as a basis for the formulation of guarantees on cavitation pitting on Pelton turbine runners. It also provides a basis for the measurement and evaluation of the amount of cavitation pitting on Pelton turbine runners of a given turbine, which is defined in the contract by(...)
  • Summarizes the present position on difference in limits and attitudes towards non-ionizing hazards adopted by a number of different countries, and by the IEC and other international organizations, in standards and recommendations.
  • Lays down principles for testing I&C systems performing category A, B and C functions, per IEC 61226, during normal power operation and shutdown, so as to check the functional availability especially with regard to the detection of faults that could prevent the proper operation of the(...)
  • Recommendations are presented for uniform practice with regard to block transfers in CAMAC modular instrumentation and digital interface systems of IEC 60516.
  • Provides general guidance on how to reduce to acceptable levels the risk of fire and the potential effects of fires involving electrotechnical products. It also describes the relationship between fire risk and the potential effects of fire, it also emphasises the importance of the scenario(...)
  • IEC 60695-1-11:2014 provides guidance for assessing the fire hazard of electrotechnical products and for the resulting development of fire hazard testing as related directly to harm to people, animals or property. It outlines a hazard-based process to identify appropriate fire test methods and(...)
  • Provides guidance for assessing and choosing candidate materials, components or sub-assemblies for making an end-product based upon preselection testing. It describes how preselection provides comparative fire hazard test methods to evaluate the performance of a test specimen and how(...)
  • Provides guidance on the minimization of fire hazard arising from the use of electrical insulating liquids, with respect to: electrotechnical equipment and systems and people, building structures and their contents.
  • Specifies the glow-wire apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors, for short periods, in order to assess the fire hazard by a simulation technique.
  • Specifies the details of the glow-wire test to be applied to end-products for fire hazard testing. For the purpose of this standard, end-product means electrotechnical equipment, its subassemblies, and components.
  • Specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for flammability testing to determine the glow-wire flammability index (GWFI).
