ISO/IEC 10373-6:2020

Overview - ISO/IEC 10373-6:2020 (Contactless proximity objects)

ISO/IEC 10373-6:2020 is Part 6 of the ISO/IEC 10373 series and specifies test methods for contactless proximity cards and objects (proximity coupling devices and proximity extended devices). It defines measurement setups, apparatus and procedures to verify physical and radio-frequency characteristics of devices that implement ISO/IEC 14443-1 through -4 technologies. The document is a test-method standard: it describes how to perform tests, while acceptability criteria remain defined in the referenced base standards.

Key topics and technical requirements

This standard focuses on reproducible laboratory test methods for proximity (13.56 MHz) contactless devices. Key technical topics include:

• Test environment and pre-conditioning requirements (temperature, humidity, DUT positioning and handling).
• Apparatus and measurement setups, including calibration coils, test PCD antennas, sense coils, and minimum instrumentation (oscilloscope and related measurement tools).
• Reference devices: reference PICC and active reference PICC designs used for comparative measurements.
• ISO/IEC 14443 parameter tests, such as alternating magnetic field checks, PCD field strength, modulation index and waveform analysis, phase stability, and PICC resonance and transmission characteristics.
• Load modulation and high bit‑rate tests to validate PICC-to-PCD communication performance.
• Electromagnetic disturbance (EMD) immunity and recovery tests to assess robustness against interference.
• Specialized analysis tools and software aids provided in annexes (e.g., modulation index analysis, EMD measurement programs).
• Conformance test plan (Annex O) listing applicable tests mapped to each part of ISO/IEC 14443.

Applications and who uses it

ISO/IEC 10373-6 is used by professionals involved in the design, production, testing and certification of contactless identification devices:

• Manufacturers of proximity cards, tags and modules use these test methods for product verification and quality control.
• Independent test laboratories and certification bodies apply the procedures for conformance testing and compliance reporting.
• System integrators and solution providers validate interoperability of PCDs (readers) and PICCs (cards/tokens) in access control, public transport ticketing, NFC-enabled devices, identity credentials and contactless payment ecosystems.
• Regulatory and procurement teams reference the standard to define test requirements in specifications and tenders.

Related standards

• ISO/IEC 10373 series (general test methods)
• ISO/IEC 7810 (identification card formats)
• ISO/IEC 14443‑1, ‑2, ‑3, ‑4 (contactless proximity card communication protocols)

By implementing ISO/IEC 10373-6:2020 test methods, organizations can ensure consistent, repeatable verification of contactless proximity device performance and interoperability with ISO/IEC 14443-based systems.
