ISO/IEC 30116:2016

ISO/IEC 30116:2016
-      specifies the methodology for the measurement of specific attributes of OCR-B character strings,
-      defines a method for evaluating these measurements and deriving an overall assessment of character string quality,
-      defines a reference decode algorithm for OCR-B, and
-      gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
ISO/IEC 30116:2016 applies to OCR-B as defined in ISO 1073-2, but its methodology can be applied partially or wholly to other OCR fonts.
