10 unusual facts about International Electrotechnical Commission


AIS-SART

The specification (IEC 61097-14 Ed 1.0) for AIS-SART was developed by the IEC's TC80 AIS work group.

Elihu Thomson

He was a founding member, as well as the second president, of the International Electrotechnical Commission.

Extra-low voltage

The International Electrotechnical Commission and its member organizations define an ELV circuit as one in which the electrical potential of any conductor against earth (ground) is not more than either 25 volts RMS (35 volts peak) for alternating current, or ripple-free 60 volts for direct current under dry conditions.

International Electrotechnical Commission

Originally located in London, the commission moved to its current headquarters in Geneva in 1948.

International Society of Automation

Many ISA standards have also gone to be adopted as international (International Electrotechnical Commission (IEC) standards as well.

This standard was approved by the International Electrotechnical Commission (IEC) as a publicly available specification, or PAS in September 2011.

Nominal impedance

The International Electrotechnical Commission defines a similar set of nominal impedances, but also has a coarser classification of low, medium and high impedance with medium being 600 Ω to 10 kΩ.

Soil resistivity

Because of the variability of soil resistivity, IEC standards require that the seasonal variation in resistivity be accounted for in transmission system design.

Telebiometrics

"Telebiometrics related to human physiology, IEC 80000-14" specification is one of a set of International Standards produced jointly by the International Organisation for Standardisation (ISO) and the International Electrotechnical Commission (IEC) under their Joint Technical Committee.

Vector group

In electrical engineering, a vector group is the International Electrotechnical Commission (IEC) method of categorizing the high voltage (HV) windings and low voltage (LV) winding configurations of three-phase transformers.


AAA battery

A carbon-zinc battery in this size is designated by IEC as "R03", by ANSI C18.1 as "24", by old JIS standard as "UM 4", and by other manufacturer and national standard designations that vary depending on the cell chemistry.

C++

In 1998, the C++ standards committee (the ISO/IEC JTC1/SC22/WG21 working group) standardized C++ and published the international standard ISO/IEC 14882:1998 (informally known as C++98).

CR2032 battery

Battery nomenclature is defined by the International Electrotechnical Commission (IEC) in its 60086 standard "Primary batteries".

National Imagery Transmission Format

NITF has adopted the ISO/IEC 15444-1 standard for imagery compression, JPEG 2000.

Scalable Video Coding

H.264/MPEG-4 AVC was developed jointly by ITU-T and ISO/IEC JTC 1.

Volt-ampere reactive

The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power.
