Template:Short description ISO 31 (Quantities and units, International Organization for Standardization, 1992) is a superseded international standard concerning physical quantities, units of measurement, their interrelationships and their presentation.[1] It was revised and replaced by ISO/IEC 80000.
Parts
The standard comes in 14 parts:
- ISO 31-0: General principles (replaced by ISO/IEC 80000-1:2009)
- 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)
- ISO 31-5: Electricity and magnetism (replaced by ISO/IEC 80000-6)
- ISO 31-6: Light and related electromagnetic radiations (replaced by ISO/IEC 80000-7)
- ISO 31-7: Acoustics (replaced by ISO/IEC 80000-8:2007)
- ISO 31-8: Physical chemistry and molecular physics (replaced by ISO/IEC 80000-9)
- ISO 31-9: Atomic and nuclear physics (replaced by ISO/IEC 80000-10)
- ISO 31-10: Nuclear reactions and ionizing radiations (replaced by ISO/IEC 80000-10)
- 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 (replaced by ISO/IEC 80000-11)
- ISO 31-13: Solid state physics (replaced by ISO/IEC 80000-12)
A second international standard on quantities and units was IEC 60027.[2] The ISO 31 and IEC 60027 Standards were revised by the two standardization organizations in collaboration ([1], [2]) 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.
Coined words
ISO 31-0 introduced several new words into the English language that are direct spelling-calques from the French.[3] Some of these words have been used in scientific literature.[4][5][6][7]
| New phrase | Existing phrase | Technical meaning |
|---|---|---|
| massic <quantity> | specific <quantity> | a quantity divided by its associated mass |
| volumic <quantity> | [volumic] <quantity> density | a quantity divided by its associated volume |
| areic <quantity> | surface <quantity> density | a quantity divided by its associated area |
| lineic <quantity> | linear <quantity> density | a quantity divided by its associated length |
Related national standards
- Canada: CAN/CSA-Z234-1-89 Canadian Metric Practice Guide (covers some aspects of ISO 31-0, but is not a comprehensive list of physical quantities comparable to ISO 31)
- United States: There are several national SI guidance documents, such as NIST SP 811, NIST SP 330, NIST SP 814, IEEE/ASTM SI 10, SAE J916. These cover many aspects of the ISO 31-0 standard, but lack the comprehensive list of quantities and units defined in the remaining parts of ISO 31.
See also
- SI – the international system of units
- BIPM – publishes freely available information on SI units [3], which overlaps with some of the material covered in ISO 31-0
- IUPAP – much of the material in ISO 31 comes originally from Document IUPAP-25 of the Commission for Symbols, Units and Nomenclature (SUN Commission) [4] of the International Union of Pure and Applied Physics
- IUPAC – some of the material in ISO 31 originates from the Interdivisional Committee on Terminology, Nomenclature and Symbols [5] of the International Union of Pure and Applied Chemistry
- Quantities, Units and Symbols in Physical Chemistry – this IUPAC "Green Book" covers many ISO 31 definitions
- IEC 60027 Letter symbols to be used in electrical technology
- ISO 1000 SI Units and Recommendations for the use of their multiples and of certain other units (bundled with ISO 31 as the ISO Standards Handbook – Quantities and units)
