Overview - ISO/IEC 15457-3:2008 (Identification cards - Thin flexible cards - Test methods)

ISO/IEC 15457-3:2008 specifies standardized test methods and procedures for evaluating thin flexible identification cards, with particular emphasis on magnetic stripe and encoding characteristics. The standard addresses how to prepare, condition, sample and test finished cards used for mass transit, highway tolling, car parks, vouchers, stored-value systems and other machine-read applications. Note: acceptance criteria are not part of this standard - ISO/IEC 15457-3:2008 defines how to measure properties, not pass/fail limits.

Key Topics and technical requirements

The document organizes practical, repeatable test procedures for physical and magnetic properties. Key topics include:

• General test protocol: sampling, conditioning, test environment and test reporting for finished cards.
• Physical characteristics: dimensional checks (except thickness), thickness measurement, separation force, reel winding, bursting strength, stiffness, folding endurance, tear resistance, delamination resistance and cold‑crack (brittleness) testing.
• Surface & optical properties: smoothness, reflectance, opacity, ash content, coefficient of friction and destacking force, air permeance, sizing and pen‑writing factor.
• Magnetic stripe physical tests: stripe protrusion, profile deviation, roughness, warpage, adherence, wear testing and dimensional measurements of the magnetic track.
• Static magnetic characteristics: principles, apparatus and sample preparation for measuring magnetic encoding properties.
• Test execution rules: most tests apply to finished cards and are performed on separate samples - individual cards are not intended to go through multiple destructive tests.

Practical applications

ISO/IEC 15457-3:2008 is used to ensure consistent, reproducible measurement of card properties that affect durability, machine readability and handling in real-world systems:

• Validate magnetic stripe quality and mechanical robustness for transit and tolling cards
• Guide quality control and incoming inspection of thin flexible card batches
• Support failure analysis and supplier qualification for card materials and lamination processes
• Provide laboratory procedures for standardized test reports used in procurement and compliance documentation

Who should use this standard

• Card manufacturers and converters (production quality control)
• Materials suppliers (substrate and stripe vendors)
• Independent testing laboratories and QA teams
• System integrators and buyers specifying card durability and machine-read performance
