ISO 31

Last updated

ISO 31 (Quantities and units, International Organization for Standardization, 1992) is a superseded international standard concerning physical quantities, units of measurement, their interrelationships and their presentation.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

Contents

Parts

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 (, ) 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]

massic <quantity>specific <quantity> a quantity divided by its associated mass
