In IEC 80000-6:2008, names, symbols, and definitions for quantities and units of electromagnetism are given. 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, units, symbols, conversion factors.

Specifies procedures for applying and preparing compliance test plans for success ratio or failure ratio. The procedures are based on the assumption that each trial is statistically independent. Supersedes IEC 605-5 and its amendment 1.

Should be used in conjunction with IEC 61120-1 and IEC 61120-3.
