IEC Standards

This International Standard’s purpose is to specify the performance, general features, mechanical properties, environmental conditions, testing procedures, and documentation for installed monitors utilized in detecting gamma and neutron radiation emitters within objects, containers, or vehicles. The standard is intended for installed monitors that are designed to identify special nuclear and other radioactive materials through the […]

BS IEC 61226:2005 defines a classification method for the information and command functions within nuclear power plants, along with the instrumentation and control (I&C) systems and equipment that facilitate those functions. The classification categorizes these functions based on their importance to safety, which in turn informs the relevant design criteria. The design criteria serve as

BS IEC 61225:2005 outlines the performance and functional characteristics required for electrical supply systems that support the instrumentation and control (I&C) systems critical to the safety of nuclear power plants. It also provides guidance regarding the potential application of these supplies for other I&C systems. These power supplies should be sourced from primary systems that

BS IEC 60860:2014 is intended for equipment designed to alert of a criticality accident through the detection of gamma radiation, neutrons, or both. The standard primarily focuses on equipment design rather than the placement of such equipment. The placement requirements for criticality alarm systems, as well as their operational procedures, are detailed in ISO 7753

BS IEC 60568:2006 pertains to on-line in-core neutron detectors, along with their associated components and instrumentation, which are crucial for reactor safety in terms of protection, information, or control. The commonly used detector types include direct current ionization chambers, fission ion chambers, and self-powered neutron detectors. This standard offers guidance on designing in-core instrumentation for

BS IEC 60313:2002 pertains to coaxial connectors designed for electrical instruments utilized in nuclear laboratories. Although these connectors are especially beneficial for such applications, they can also be applicable in other contexts. However, this standard may not be suitable for nuclear power installations, where specific requirements might require the use of alternative connectors, some of
