IEC/TS 62720:2013规定了支持产品数据计算机处理的装置标识符。它提供了一项数量调查，包括商业和科学中使用的国际标准化和非标准化单位的相关集合。它涉及两个或两个以上不同的民族语言群体或国家，至少在一个行业领域，目前使用的任何标准或非标准度量单位，对于这些标准或非标准度量单位，明确的转换为已知标准度量单位或其等价物的方法有充分的文件记录，或从外部参考中明显可见。

IEC/TS 62720:2013 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. It concerns 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.
