ISO/IEC 18047-3:2022

Overview

ISO/IEC 18047-3:2022 specifies conformance test methods for radio frequency identification (RFID) devices - both tags and interrogators - that operate at 13.56 MHz and are used for item management. The document defines how to verify mandatory functions and any implemented optional functions against the air‑interface parameters given in ISO/IEC 18000‑3. It focuses on functional and interoperability parameters for Mode 1, Mode 2 and Mode 3 air interfaces and explicitly does not cover regulatory compliance testing or high‑level data encoding conformance (see ISO/IEC 15962).

Key topics and technical requirements

• Scope of testing: Conformance verification of tag and interrogator behavior relative to ISO/IEC 18000‑3 parameters (mode‑specific nominal values and tolerances).
• Default test conditions: Environmental conditions (23 °C ± 3 °C, 40–60 % RH), 24‑hour pre‑conditioning for tags when required, and a default tolerance of ±5 % for test equipment and procedure dimensions.
• Measurement rigor: Requirement to state total measurement uncertainty in test reports (reference to ISO/IEC Guide 98‑3).
• Test apparatus and circuits: Defined test elements include calibration coils (PCB coil details and substrate thickness 0.76 mm ±10 %), test interrogator assembly (interrogator antenna plus sense coils for load modulation), reference tags, and digital sampling oscilloscopes.
• Mode‑specific tests: Separate conformance procedures and circuits for ISO/IEC 18000‑3 Mode 1, Mode 2 and Mode 3 (mandatory ASK part), with annexes detailing dimensions and setups for tag sizes, test antennas, sense coils and reference tags.
• Exclusions: Regulatory parameters and high‑level encoding conformance (handled in ISO/IEC 15962) are out of scope.

Practical applications and users

• Who uses it: RFID test laboratories, device manufacturers, product quality and compliance engineers, systems integrators and certification bodies performing laboratory conformance testing.
• Why it matters: Ensures interoperability, predictable performance and functional conformance of 13.56 MHz RFID devices used in item management (e.g., inventory, logistics, asset tracking). Results are used to validate product design, support certification and reduce field interoperability issues.
• Typical outcomes: Measured conformance reports that compare device behavior to ISO/IEC 18000‑3 parameters, documented measurement uncertainty, and reproducible test setups described in normative annexes.
