    Definition
  • This part of IEC 61482 specifies methods to test material and garments intended for use in heat- and flame-resistant clothing for workers exposed to electric arcs. In contrast to the test methods in IEC 61482-1-1 a directed and constrained electric arc in a low voltage circuit is used to(...)
  • Applicable to protective clothing used in work if there is an electric arc hazard. Specifies requirements and test methods applicable to materials and garments for protective clothing for electrical workers against the thermal hazards of an electric arc based on: relevant general properties of(...)
  • Specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety related system.
  • Specifies requirements for the design, construction and testing of electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety-related system, employing active opto-electronic protective devices (AOPDs) for the sensing function.
  • Specifies additional requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety related system, employing active opto-electronic protective devices responsive to diffuse(...)
  • IEC 61500:2009 establishes requirements for data communication which is used in systems performing category A functions in nuclear power plants. It covers also interface requirements for data communication of equipment performing category A functions with other systems including those(...)
  • Describes the principles, the terminology, the characteristics, the requirements and the testing methods related to instrumentation and measurement of the neutron fluence rate using mean square voltage techniques for nuclear reactor control.
  • Applies to systems used for monitoring the vibratory behaviour of the internal structures of pressurized water reactors (core barrel, thermal shield, upper and lower core support, etc.) and fuel assemblies on the basis of neutron fluctuations observed outside the vessel and vessel vibrations.(...)
  • Covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions
  • IEC 61508-2:2010 applies to any safety-related system, as defined by IEC 61508-1, that contains at least: one electrical, electronic or programmable electronic element; applies to all elements within an E/E/PE safety-related system; specifies how to refine the E/E/PE system safety requirements(...)
  • IEC 61508-3:2010 applies to any software forming part of a safety-related system or used to develop a safety-related system within the scope of IEC 61508-1 and IEC 61508-2; provides specific requirements applicable to support tools used to develop and configure a safety-related system within(...)
  • IEC 61508-4:2010 contains the definitions and explanation of terms that are used in parts 1 to 7 of the IEC 61508 series of standards. The definitions are grouped under general headings so that related terms can be understood within the context of each other. However, it should be noted that(...)
  • IEC 61508-5:2010 provides information on the underlying concepts of risk and the relationship of risk to safety integrity (see Annex A); a number of methods that will enable the safety integrity levels for the E/E/PE safety-related systems to be determined (see Annexes C, D, E, F and G). The(...)
  • IEC 61508-6:2010 contains information and guidelines on IEC 61508-2 and IEC 61508 3. Annex A gives a brief overview of the requirements of IEC 61508-2 and IEC 61508-3 and sets out the functional steps in their application. Annex B gives an example technique for calculating the probabilities of(...)
  • IEC 61508-7:2010 contains an overview of various safety techniques and measures relevant to IEC 61508-2 and IEC 61508-3.The references should be considered as basic references to methods and tools or as examples, and may not represent the state of the art.
  • Gives requirements for the specification, design, installation, operation and maintenance of a safety instrumented system, so that it can be confidently entrusted to place and/or maintain the process in a safe state.
  • Provides guidance on the specification, design, installation, operation and maintenance of Safety Instrumented Functions and related safety instrumented system as defined in IEC 61511-1.
  • IEC 61513:2011 provides requirements and recommendations for the overall I&C architecture which may contain either or both technologies.
  • Specifies general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose(...)
  • IEC 61558-2-10:2014 deals with the safety of separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V. Transformers incorporating electronic circuits are also covered by this standard.
