The present International Standard is designated for radiation detectors that are situated outside the core of nuclear reactors and supply electrical input signals to the reactor’s control and instrumentation system. These detectors are predominantly gas-filled neutron detectors, and the standard pertains exclusively to this category, although its principles may be adaptable to other types, such […]

IEC 60470:2000 applies to a.c. contactors and/or contactor-based motor starters designed for indoor use, operating at frequencies up to and including 60 Hz, on systems with voltages exceeding 1,000 V but not exceeding 12,000 V. It specifically addresses three-pole contactors and starters intended for three-phase systems, as well as single-pole contactors and starters for single-phase

IEC 60447:2004 outlines general principles for manually operated actuators that are part of the man-machine interface related to electrical equipment. Its objectives are to: Enhance safety (for individuals, property, and the environment) through the safe operation of the equipment. Support the proper and timely functioning of the actuators. These principles are applicable not only during

This standard determines the capability of insulating materials to induce electrolytic corrosion on metals when in contact with them under the influence of electric stress, high humidity, and elevated temperature. To evaluate the effect of electrolytic corrosion, two methods are employed in one test: The visual semi-quantitative method involves comparing the corrosion observed on the

IEC 60423:2007 details the outer diameters of conduits utilized in electrical installations or within communication systems, along with the dimensional specifications for threads. Additionally, it outlines the dimensional requirements for threads employed in the corresponding fittings. The standard does not cover extra-heavy-duty electrical rigid steel conduits as defined in IEC 60981.
