DANSK DS/EN IEC 80000-6 PDF

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.
