What are the standards for Data Matrix verification?
A. The two most common standards are ISO/IEC 15415 and AS9132A. The ISO/IEC 15415 standard specifies the methodologies for measuring, evaluating, and grading 2D symbol characteristics in order to indicate the quality of the mark. In addition, the standard identifies possible causes for symbol degradation. See below for complete parameters. The AS9132A standard specifies uniform quality and technical requirements for Data Matrix direct part marking symbols on metal substrates. Direct part marking methods addressed in the AS9132A standard include: dot peen, laser etch, and electrochemical etch. Manufacturers of aerospace components are directly affected by the AS9132A standard. Q. How do I choose a verifier? A. Certified verifiers are highly desirable. The lighting and optics of the verifier must be factory calibrated to gain ISO/IEC 15426-2 certification, which guarantees accurate and consistent verification results from one verifier to another. Currently the only Data Matrix verifier t
