Scope: This standard specifies the methods for the detection and grading of layered and matrix two-dimensional barcode symbols and the evaluation of the overall quality of the symbols, and gives the possible reasons for deviation from the optimal level and corresponding corrective measures. This standard applies to the inspection of the printing quality of two-dimensional barcode symbols for which the reference decoding algorithm has been given in the two-dimensional barcode code system specification, and its method can also be partially or completely applied to the inspection of other code system two-dimensional barcode symbols.
