ISO/IEC 80000

From Wikipedia, the free encyclopedia

International standard ISO 80000 or IEC 80000 (depending on which of the two rivaling international standards bodies International Organization for Standardization and International Electrotechnical Commission is in charge of each respective part), is the successor of ISO 31 and IEC 60027, the most widely respected style guide for the use of physical quantities and units of measurement, and formulas involving them, in scientific and educational documents worldwide. In most countries, the notations used in mathematics and science textbooks at schools and universities follow closely the guidelines given by these standards.

The ISO/IEC 80000 family of standards is still under development and only some of its parts have been published as of 2008. It has been proposed that the quantities and equations used with the SI will be known as the International System of Quantities.

[edit] Parts

The "Quantities and units" standard will eventually come in 14 parts:

  • ISO 80000-1: General (formerly ISO 31-0 and IEC 60027-1)
  • ISO 80000-2: Mathematical signs and symbols to be used in the natural sciences and technology (formerly ISO 31-11)
  • ISO 80000-3: Space and time (formerly ISO 31-1 and ISO 31-2)
  • ISO 80000-4: Mechanics (formerly ISO 31-3)
  • ISO 80000-5: Thermodynamics (formerly ISO 31-4)
  • IEC 80000-6: Electromagnetism (formerly ISO 31-5)
  • ISO 80000-7: Light
  • ISO 80000-8: Acoustics
  • ISO 80000-9: Physical chemistry and molecular physics
  • ISO 80000-10: Atomic and nuclear physics
  • ISO 80000-11: Characteristic numbers
  • ISO 80000-12: Solid state physics
  • IEC 80000-13: Information science and technology (formerly subclauses 3.8 and 3.9 of IEC 60027-2:2005)
  • IEC 80000-14: Telebiometrics related to human physiology
