ISO 28219:2017 — Labelling and Direct Product Marking with Linear Bar Code and 2D Symbols

Packaging — Labelling and direct product marking with linear bar code and two-dimensional symbols

Introduction to ISO 28219:2017

ISO 28219:2017 defines minimum requirements for labelling and direct product marking with linear bar code and two-dimensional symbols. Developed by ISO/TC 122 (Packaging), this second edition supersedes the 2009 version along with ANS MH10.8.7, CEA-802, and CEA-621-A. The standard provides a cross-industry framework applicable to automotive, aerospace, electronics, healthcare, telecommunications, and many other sectors. It covers both adhesive labels and direct part marking (DPM) methods including dot peen, laser etch, chemical etch, ink jet, and vacuum deposition processes.

ISO 28219 bridges the gap between industry-specific marking standards, providing one common multi-industry specification. For suppliers serving multiple sectors, adopting this single standard dramatically simplifies compliance across different customer requirements.

Data Format and Identifier Systems

The standard accommodates two parallel data identifier systems: Data Identifiers (DIs) per ANS MH10.8.2 and GS1 Application Identifiers (AIs). This dual-track approach allows different industries to continue using their preferred identifier conventions while maintaining a common framework. Mandatory data fields include enterprise identification (using registered issuing agency codes per ISO/IEC 15459), part number, and serial or lot/batch number. The data syntax follows ISO/IEC 15434 for high-capacity ADC media, ensuring interoperability across different symbol systems. Maximum field length is 25 data characters unless otherwise specified.

Data Element DI Example (ANSI MH10.8.2) AI Example (GS1) Mandatory/Optional
Enterprise ID 1PABC Corp (01) 12345678901234 Mandatory
Part number 1K12345-678 (01) includes in GTIN Mandatory
Serial number S123ABC (21) 123ABC Required for unique ID
Lot/batch number 1TLOT2023-05 (10) LOT2023-05 Required for group ID
Date code 4D2023-05-15 (11) 230515 Optional
Quantity Q100 (37) 100 Optional

Symbol Requirements and Print Quality

ISO 28219 specifies symbology selection recommendations for different applications. For linear bar codes, Code 128 and Code 39 are recommended, each with specific minimum element widths, quiet zone dimensions, and aspect ratios. For two-dimensional symbols, Data Matrix, QR Code, and PDF417 are specified with cell size, symbol grade, and error correction requirements. Composite symbols combining linear and 2D components are also addressed. Print quality must be verified per ISO/IEC 15415 (2D) and ISO/IEC 15416 (linear). The standard also includes detailed adhesive label requirements covering material selection, adhesion testing, environmental resistance, and mark durability — essential for parts that undergo washing, painting, or exposure to harsh environments.

Symbol placement and mark durability are frequently underestimated in implementation. A technically perfect barcode is worthless if placed where it cannot be scanned or if it degrades during manufacturing processes. Always validate mark durability through the full production cycle including any paint, heat treatment, or cleaning operations.

Implementation Guidance and Industry Applications

The standard includes extensive informative annexes covering label adhesive characteristics, commonly used identifiers, character set tables (ISO/IEC 646), data syntax guidance (ISO/IEC 15434), and specific application notes. Annex H provides serialization guidance for electronic products — a critical reference for high-volume electronics manufacturing. Special attention is given to the DUNS Number and issuing agency code registration processes, ensuring global uniqueness of enterprise identifiers. The standard explicitly addresses the needs of supply chain applications including production control, inventory management, distribution tracking, field service, point-of-sale, and repair operations.

The most successful implementations of ISO 28219 integrate barcode data directly with enterprise resource planning (ERP) and manufacturing execution systems (MES). The standard’s structured data format is designed to enable seamless automated data capture from receiving through shipping.

Engineering Design Insights

When designing an ISO 28219-compliant marking system, engineers must consider the substrate material (metal, plastic, composite), the marking method’s effect on material properties (laser etching may create stress risers), the full environmental exposure profile (temperature, chemicals, abrasion), and the scanning environment (fixed-mount vs. handheld readers, lighting conditions, reading distance). The choice between DI and AI systems should be driven by the predominant industry convention of the customers, not internal preference. For parts requiring both human-readable and machine-readable identification, the standard requires the human-readable interpretation to appear adjacent to the barcode symbol.

Q1: What is the difference between a label and direct part marking under ISO 28219?
A: A label is an adhesive-backed media attached to the item. Direct part marking (DPM) is applied directly to the item surface through methods like laser etching, dot peening, or ink jet printing.
Q2: Can I use UPC-A barcodes for item identification under this standard?
A: Yes, UPC-A (and UPC-E, EAN-8, EAN-13) are exceptions that do not require explicit Data Identifiers or Application Identifiers, as the symbology itself encodes the identifier structure.
Q3: How do I choose between Data Matrix and QR Code?
A: Data Matrix is generally preferred for direct part marking on industrial items due to its small footprint and high error correction. QR Code is more suitable for consumer-facing applications and when higher data capacity is needed.
Q4: What testing is required to verify adhesive label durability?
A: Annex A describes tests for adhesion, abrasion resistance, chemical resistance, and environmental exposure (temperature cycling, humidity, UV) that should be performed based on the intended application conditions.
