Letter symbols to be used in electrical technology - Part 3: Logarithmic and related quantities, and their units

Applies to logarithmic quantities and units. Quantities that can be expressed as the logarithm of a dimensionless quantity, such as the ratio of two physical quantities of the same kind, can be regarded and treated in different ways. In many cases, differences do not affect practical treatment.

Formelzeichen für die Elektrotechnik - Teil 3: Logarithmische und verwandte Größen und ihre Einheiten

Symboles littéraux à utiliser en électrotechnique - Partie 3: Grandeurs logarithmiques et connexes, et leurs unités

La présente norme s'applique aux grandeurs et unités logarithmiques. Les grandeurs exprimables au moyen du logarithme d'une grandeur sans dimension, qui peut être, par exemple, un rapport de deux grandeurs physiques de même nature, peuvent être interprétées et traitées de différentes manières. Mais, dans beaucoup de cas, ces différences dans les principes n'affectent pas l'utilisation pratique.
