Describes identifiers for units to support computer-based processing of product data.

This document specifies identifiers for units to support computer-based processing of product data. It provides a survey of quantities with associated collections of internationally standardized as well as non–standardized units used in business and science.

Within the scope of this document are any standard or non-standard units of measure currently in use, in two or more distinct ethno-linguistic groups or nations, at least in one domain of industry, for which an explicit method of conversion to a known standard unit of measure or its equivalent is well documented or evident from external references.

IEC 62720 collects units commonly used in business data. It does not purport to be complete. The standardization of units or parts thereof is out of the scope of this document.

NOTE Having assigned an identifier by being mentioned in this document does not imply that the unit of measure in question or parts thereof can be considered to be standardized.
