This document gives general information and definitions concerning quantities, systems of quantities, units, quantity and unit symbols, and coherent unit systems, especially the International System of Quantities (ISQ).
The principles laid down in this document are intended for general use within the various fields of science and technology, and as an introduction to other parts of this International Standard.
The ISO/IEC 80000 series does not, as yet, cover ordinal quantities and nominal properties.

IEC 80000-6:2022 gives names, symbols, and definitions for quantities and units of electromagnetism. Where appropriate, conversion factors are also given. International Standard IEC 80000-6 has been prepared by IEC technical committee 25: Quantities and units, and their letter symbols in close cooperation with ISO/TC 12, Quantities and units.
This standard is based on classical electromagnetism, i.e. mainly Maxwell’s equations. No reference is made to quantum field theories.
IEC 80000-6:2022 cancels and replaces the first edition published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
1) With the new definitions in SI, some previously exact values for quantities now must be determined experimentally while other quantities are given as exact values;
2) Item 6-2.2, elementary charge added;
3) Item 6-11.4, induced voltage, added;
4) Index of entries added;
5) Editorial alignment to other parts of the IEC and ISO 80000 series.

This document defines terms related to the concepts and quantities characterizing some classes of aircraft motion and their fundamental dynamic characteristics. The aircraft is assumed to be rigid, of constant mass and of constant inertia. It is not equipped with systems modifying its natural dynamic behaviour. However, most of the definitions can be applied to the case of a flexible aircraft, of variable mass and of variable inertia. The general concepts defined in this document are applicable to the atmospheric flight phase.
