IEC 60027 (formerly IEC 27) is a

letter symbols published by the International Electrotechnical Commission
(IEC), comprising the following parts:

  • IEC 60027-1: General
  • IEC 60027-2: Telecommunications and electronics
  • IEC 60027-3: Logarithmic and related quantities, and their units
  • IEC 60027-4: Symbols for quantities to be used for rotating electrical machines
  • IEC 60027-6: Control technology
  • IEC 60027-7: Physiological quantities and units

A closely related international standard on

units is ISO 31. The ISO 31 and IEC 60027 Standards are being revised by the two standardization organizations in collaboration. The revised harmonized standard is known as ISO/IEC 80000
, Quantities and units. It supersedes both ISO 31 and part of IEC 60027.

IEC 60027-2

IEC 60027-2 Amendment 2, as published in January 1999, was the first international standard defining the

IEC 80000-13:2008 standard supersedes subclauses 3.8 and 3.9 of IEC 60027-2:2005. The only significant change is the addition of explicit definitions for some quantities.[7]
