This standard sets forth the requirements for installation, inspection, and testing of Class IE electric power, instrumentation, and control equipment and systems during the construction phase of a nuclear power generating station. These requirements are intended to assure that only materials and equipment of acceptable quality are incorporated into the plant, that quality is maintained and quality workmanship prevails throughout the construction process, and that completed installations… read more conform to specified requirements, so as to promote public safety, prevent accidents, and mitigate the consequences of accidents if they occur, and provide a high degree of plant reliability. read less

This project provides recommended practices for the prediction and practical determination of safe distances from radio and radar transmitting antennas when using electric initiators to remotely detonate an explosive charge. Specifically, this document includes mathematical formulas, tables, and charts that allow the user to determine safe distances from RF transmitters with spectrum bands from 0.5 MHz to 300 GHz, including VHF, UHF television antennas, FM, AM radio transmitting antennas, radar… read more navigation beacons, and portable communication devices. This document excludes criteria for the use of electro-explosive devices (EEDs) within electrically conductive enclosures or weapons and does not include discussion of hazards deriving from electromagnetic fields generated by other sources of energy such as electrical storms, electromechanical equipment, electrical power plants or power transmission lines. read less

The standard establishes a set of processes by which engineers and technologists can include consideration of ethical values throughout the stages of concept exploration and development, which encompass system initiation, analysis, and design. This standard provides engineers and technologists with an implementable process aligning innovation management processes, system design approaches, and software engineering methods to help address ethical concerns or risks during system design. IEEE Std 7… read more 000 does not give specific guidance on the design of algorithms to apply ethical values such as fairness and privacy. read less

This document recommends best practices for the measurement of partial discharges using AC voltages and VHF/UHF electromagnetic sensors for quality control during routine tests on factory and pre-moulded joints of HVDC extruded cable systems with rated voltage up to 800 kV. This recommended practice addresses the whole phenomenon of partial discharges, rather than solely on partial discharge pulse amplitude, in order to assess whether critical partial discharges are present in the tested object… read more (either a factory joint or a pre-moulded joint of a HVDC extruded cable system). By "critical partial discharge" it is meant here a discharge within the insulation of the object under test, excluding all external discharges that can be present during the AC voltage test, e.g. corona discharges due to HV electrodes, conducting leads, etc. related to the test setup. read less
