IUID product verification is recommended to manufacturers before completing DoD registration. The verification process involves verification of MRI, or machine readable, data. Today, software technology is used to scan machine readable data (MRI) for compliance. Equipment used in many of today’s internal IUID verification systems are better known as sophisticated vision systems with specialized software.

The verification process for many manufacturers differs based on selected marking methods and bar code reader types. Specialized IUID verifiers are available with many different capabilities. Broadly, there are two primary classifications: These include DPM verifiers and LPD verifiers.

DPM verification system

This process is applied to IUID nameplates that have information directly engraved on them. Direct part marking is MIL-STD-130 affiliated. However, nameplate suppliers have to follow certain specifications in the case of engraved or laser-etched products. For compliance, DPM verifiers must validate product identification based on these specifications:

✓ DPM verifiers have to identify the right size of data matrix codes. According to MIL-STD-130, the cell size of a compliant data matrix code must be larger than .005 inches and no greater than .025 inches.

✓ A DPM IUID verifier should be able to identify all available lighting options for IUID data scanning for the most realistic testing. Popular options include medium angle, low angle, diffused off axis, and diffused perpendicular lighting.

Verification system for labels and data plates

Verification of IUID labels and data plates can be performed in several ways. There are a number of IUID recognized verifiers. Some of the popular verification options are given below:

✓ PC-based verification software: This is a popular and powerful verification process. Software-based verifiers offer standard and convenient decoding, data verification, and validation.

✓ Portable verifiers: Portable machines are handy and offer convenient data capturing options. Most of these machines contain a small display that views details of verified data.

Utilization of IUID verifiers helps to improve IUID verification and overall MIL-STD-130 compliance. To learn more about the basics of today’s IUID verification systems, read more of our UID Verification articles.
