| BSI | 2013 | 266 |
This Technical Specification 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.
In scope 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.
NOTE 1 The document collects units commonly used in business data. It does not purport to be complete. The standardization of units or parts thereof is out of scope.
NOTE 2 Having assigned an identifier by being mentioned in IEC 62720 does not imply that the unit of measure in question or parts thereof may be considered to be standardized.
