IEC 61499-4-2013 is the fourth part of the IEC 61499 series, defining compliance profiles and rules for the application of function blocks in distributed industrial-process measurement and control systems. While Parts 1-3 of the standard specify the architecture, software tool…

IEC 61500-2018 specifies requirements for multiplexed data transmission within I&C systems important to safety in nuclear power plants. As nuclear plants have transitioned from hardwired analog control to digital I&C architectures, multiplexing has become essential for reducing cable count and…

✅ Standard at a Glance IEC 61479, first published in 2001 with a Corrigendum in 2002, specifies the requirements for insulating ropes made of synthetic fibres used in live working on electrical systems. Prepared by IEC Technical Committee 78 (Live…

✅ Standard at a Glance IEC 61481, first published in 2001 with a Corrigendum in 2004, specifies the requirements for phase comparators used in live working on electrical systems operating at voltages up to and including 800 kV AC. Prepared…

✅ Standard at a Glance IEC 61482-2, published in 2009, specifies the requirements for protective clothing designed to shield workers from the thermal effects of an electric arc. Part of the IEC 61482 series on live working arc protection, this…

IEC TR 61491-1995 is a technical report that defines block transfer protocols for the CAMAC (Computer Automated Measurement and Control) standard, a modular instrumentation system widely adopted in nuclear physics, fusion research, and high-energy physics experiments. Published as a companion…

✅ Standard at a Glance IEC 61468, published in 2000, specifies the design, performance, and testing requirements for in-core instrumentation used in nuclear reactor cores. This instrumentation includes neutron flux detectors (self-powered neutron detectors or SPNDs, fission chambers, and miniature…

✅ Standard at a Glance IEC 61472, published in 2013, specifies the methodology for determining minimum approach distances (MAD) for live working on energized electrical systems operating at nominal voltages from 1 kV to 800 kV AC and up to…

✅ Standard at a Glance IEC 61477, first published in 2009 with a Corrigendum in 2010, is the umbrella standard that defines minimum requirements, testing, and classification for all tools, devices, and equipment used in live working. It consolidates cross-cutting…

✅ Standard at a Glance IEC 61478, first published in 2001 with a Corrigendum in 2003, specifies the requirements for ladders made of insulating material used for live working on electrical systems operating at voltages up to and including 800…
