Parts
The standard comes in 14 parts:
- ISO 31-0: General principles
- ISO 31-1: Space and time (replaced by ISO/IEC 80000-3:2007)
- ISO 31-2: Periodic and related phenomena (replaced by ISO/IEC 80000-3:2007)
- ISO 31-3: Mechanics (replaced by ISO/IEC 80000-4:2006)
- ISO 31-4: Heat (replaced by ISO/IEC 80000-5:2007)
- ISO 31-5: Electricity and magnetism
- ISO 31-6: Light and related electromagnetic radiations
- ISO 31-7: Acoustics (replaced by ISO/IEC 80000-8:2007)
- ISO 31-8: Physical chemistry and molecular physics
- ISO 31-9: Atomic and nuclear physics
- ISO 31-10: Nuclear reactions and ionizing radiations
- ISO 31-11: Mathematical signs and symbols for use in the physical sciences and technology (replaced by ISO 80000-2:2009)
- ISO 31-12: Characteristic numbers
- ISO 31-13: Solid state physics
A second international standard on quantities and units was IEC 60027. The ISO 31 and IEC 60027 Standards were revised by the two standardization organizations in collaboration (, ) to integrate both standards into a joint standard ISO/IEC 80000 - Quantities and Units in which the quantities and equations used with SI are to be referred as the International System of Quantities (ISQ). ISO/IEC 80000 supersedes both ISO 31 and part of IEC 60027.

Famous quotes containing the word parts:
“It is a relief to read some true book, wherein all are equally dead,—equally alive. I think the best parts of Shakespeare would only be enhanced by the most thrilling and affecting events. I have found it so. And so much the more, as they are not intended for consolation.”
—Henry David Thoreau (1817–1862)
“Yea, worse than death: death parts both woe and joy:
From joy I part, still living in annoy.”
—Sir Philip Sidney (1554–1586)
“Irish was a man of parts even if some of them didn’t work too well.”
—Angela Carter (1940–1992)
