Industrial Marking Standards: Traceability and Quality Requirements in Manufacturing
Industrial marking is a critical identification method that ensures the traceability of products throughout the manufacturing process. Serial numbers, DataMatrix codes, QR codes, and product information are permanently marked onto parts using marking systems. These markings must comply with international standards and maintain their readability throughout the production chain. This guide explains in detail industrial marking standards, traceability requirements, and marking technologies used in modern manufacturing systems.
Industrial Marking and Traceability Standards
What is industrial marking?
Industrial marking is the process of marking products or parts with a unique identity during production. This identity may be in the form of a serial number, code, or symbol.
Why is traceability important?
Thanks to traceability, a product’s manufacturing process, the materials used, and its production date can be tracked. This provides a major advantage in quality control and recall processes.
GS1 standard
GS1 defines the standard coding systems used in the global supply chain. It is frequently used in QR code and DataMatrix applications.
ISO/IEC marking standards
ISO and IEC standards define the structure of coding systems and quality criteria.
UID and UDI systems
UID (Unique Identification) and UDI (Unique Device Identification) systems are used especially in the defense and medical industries.
Direct part marking (DPM)
Direct Part Marking refers to processing codes directly onto the part surface. This method can be performed with laser marking.
Code readability
In industrial marking systems, codes must remain readable throughout the production line.
Quality grading
Code quality is graded according to ISO standards, and readability is analyzed.
Automation systems
In modern production lines, marking systems work integrated with PLC and MES systems.
Industrial marking technologies
- Laser marking
- Dot peen marking
- Inkjet marking
- Labeling systems
Industrial Marking Applications and Technologies
