Frequently Asked Questions
How do ISO/IEC 15415 and ISO/IEC 15416 differ?
ISO/IEC 15416 grades linear barcodes, while ISO/IEC 15415 applies to two-dimensional codes. The two standards use different grading parameters. DPM marks are evaluated separately under ISO/IEC TR 29158.
Can VeriCube inspect DPM codes?
Yes. REA VeriCube supports ISO/IEC TR 29158 and can inspect laser-marked and dot-peened Data Matrix codes on metal and plastic parts, producing a grade report from 4.0 to 0.
How often should a barcode verifier be calibrated?
As an optical metrology instrument, a barcode verifier is generally recommended for annual calibration according to the manufacturer's interval, with records retained for customer and quality-system audits.
What minimum barcode grade is needed for a supplier audit?
The GS1 General Specifications set 1.5 as the minimum general symbol grade. Medical UDI, automotive, and other sectors may require a higher grade; follow the applicable customer contract or industry standard.
