ISO 31

From Wikipedia, the free encyclopedia

ISO 31 ( Quantities and units , International Organization for Standardization , 1992) is a superseded international standard concerning physical quantities , units of measurement , their interrelationships and their presentation.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 [ edit ]

The standard comes in 14 parts:

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 [ edit ]

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 [ edit ]

  • 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.
