Information technology - Radio frequency identification device conformance test methods - Part 63: Test methods for air interface communications at 860 MHz to 960 MHz

This document specficies test methods for determining the conformance of radio frequency identification (RFID) devices (tags and interrogators) for item management with the specifications given in ISO/IEC 18000-63. This document does not apply to the testing of conformity with regulatory or similar requirements. The test methods specify only the verification of the mandatory functions and any optional functions which are implemented. This can, in appropriate circumstances, be supplemented by further, application-specific functionality criteria that are not available in the general case. The interrogator and tag conformance parameters in this document are the following: - type-specific conformance parameters including nominal values and tolerances; - parameters that directly affect system functionality and inter-operability. Parameters that are already included in regulatory test requirements are not included in this document. Unless otherwise specified, the tests in this document are intended to be applied exclusively to RFID tags and interrogators defined in ISO/IEC 18000-63.

Overview

ISO/IEC 18047-63:2023 specifies conformance test methods for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz band. It provides standardized procedures to verify that RFID tags and interrogators (readers) conform to the air‑interface parameters defined in ISO/IEC 18000-63. The document focuses on mandatory functions and any implemented optional functions that affect device interoperability and system functionality. It does not replace regulatory testing (e.g., EMC or spectrum licensing) and excludes parameters already covered by regulatory test requirements.

Key topics and technical requirements

• Scope of conformance tests: Verifies type‑specific conformance parameters (nominal values and tolerances) and parameters that directly affect system interoperability.
• System model: Covers passive‑backscatter, interrogator‑talks‑first (ITF) RFID systems where tags derive power from the reader’s RF field and respond by backscattering.
• Test structure: Organized into clause groups that map to ISO/IEC 18000-63 requirements:
  • Clause 6: Baseline conformance tests for core protocol elements.
  • Clause 7: Tag functional tests (including battery‑assisted passive tag persistence, link timing, demodulation and frequency tolerance).
  • Clause 8: Interrogator functional tests (RF envelope, activation dwell time, link timings) and complementary tag tests (activation time, timers).
  • Clause 9: Sensor-related conformance tests (simple, full‑function, snapshot sensor procedures).
• Test environment and uncertainty: Default test conditions, pre‑conditioning, noise floor considerations and total measurement uncertainty are specified to ensure repeatable results.
• Test equipment setup: Normative annex (Annex A) provides guidance on configuring test instruments and test beds.

Practical applications

• Validate RFID device conformance to ISO/IEC 18000-63 air‑interface specifications.
• Ensure interoperability between tags and readers from different vendors.
• Support product development and QA through repeatable conformance testing.
• Provide test methods for certification bodies and independent test laboratories to issue conformance reports.
• Enable integrators and system designers to verify device behavior under defined link‑timing and RF conditions.

Who should use this standard

• RFID manufacturers (tags and interrogators) for product verification
• Conformity assessment and testing laboratories
• Certification bodies and procurement teams requiring standardized conformance evidence
• Systems integrators and R&D teams designing RFID solutions for item management
• QA and regulatory affairs teams seeking protocol conformance (distinct from regulatory compliance)

Related standards

• ISO/IEC 18000-63:2021 - Air interface parameters for 860 MHz to 960 MHz (Type C)
• ISO/IEC 18046 series - Performance test methods for RFID (complements conformance tests)

Introduction
The ISO/IEC 18000 series defines the air interface for radio frequency identification (RFID) devices
used in item management applications. ISO/IEC 18000-61, ISO/IEC 18000-62, ISO/IEC 18000-63 and
ISO/IEC 18000-64 define the air interface for RFID devices that operate at frequencies from 860 MHz to
960 MHz
The ISO/IEC 18047 series provides air interface communication test methods to ensure conformance
with the different parts of the ISO/IEC 18000 series.
Each part of the ISO/IEC 18047 series contains all measurements required to be made on a product to
establish whether it conforms to the corresponding part of the ISO/IEC 18000 series.
NOTE Test methods for interrogator and tag performance are covered by the ISO/IEC 18046 series.
This document specifies the conformance requirements for a passive-backscatter, interrogator-
talks-first (ITF), radio-frequency identification (RFID) system operating in the 860 MHz to 960 MHz
frequency range. The system comprises interrogators, also known as readers, and tags, also known as
labels.
An Interrogator transmits information to a Tag by modulating a radiofrequency (RF) signal in the
860 MHz to 960 MHz frequency range. The Tag receives both information and operating energy from
this RF signal. Tags are passive, meaning that they receive all of their operating energy from the
Interrogator’s RF waveform.
An Interrogator receives information from a Tag by transmitting a continuous-wave (CW) RF signal to
the Tag; the Tag responds by modulating the reflection coefficient of its antenna, thereby backscattering
an information signal to the Interrogator. The system is ITF, meaning that a Tag modulates its antenna
reflection coefficient with an information signal only after being directed to do so by an Interrogator.
Interrogators and Tags are not required to talk simultaneously; rather, communications are half-duplex,
meaning that Interrogators talk and Tags listen – or vice versa.
Clause 6 describes and specifies all necessary conformance tests for ISO/IEC 18000-63:2021, Clause 6.
Clause 7 describes all necessary conformance tests that are described in ISO/IEC 18000-63:2021, 7.1 to
7.4.
Clause 8 describes all necessary conformance tests for ISO/IEC 18000-63:2021, 7.5.
Clause 9 describes all necessary conformance tests for ISO/IEC 18000-63:2021, Clause 8.
The International Organization for Standardization (ISO) and the International Electrotechnical
Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may
involve the use of a patent.

4 Default conditions applicable to the test methods
4.1 Test environment
Unless otherwise specified, testing shall take place in a temperature environment of (23 ± 3) °C and
non-condensing humidity from 40 % to 60 %.
4.2 Pre-conditioning
4.2.1 General
Before testing, the interrogators and tags to be tested shall be conditioned to the test environment for
a period of 24 h.
4.2.2 Default tolerance
Unless otherwise specified, a default tolerance of ±5 % shall be applied to the quantity values given
to specify the characteristics of the test equipment (e.g. linear dimensions) and the test method
procedures (e.g. test equipment adjustments).
4.2.3 Noise floor at test location
Noise floor at test location shall be measured for at least 1 min with the spectrum analyser, using the
same conditions as for the measurement of the DUT.
The maximum of the measured noise amplitude, measured in a 10 kHz bandwidth, shall be −60 dB from
0,5 GHz to 2 GHz and −90 dBm around the center frequency of the tag backscatter signal.
Special attention shall be given to spurious emissions, for example, insufficiently shielded computer
monitors. The electromagnetic test conditions of the measurements shall be checked by performing the
measurements with and without a tag in the field.
4.2.4 Total measurement uncertainty
The total measurement uncertainty for each quantity determined by these test methods shall be stated
in the test report.
NOTE Basic information is given in ISO/IEC Guide 98-3.
5 Conformance
To claim conformance to ISO/IEC 18000-63, a device shall pass the conformance tests in this document.
6 Conformance tests for ISO/IEC 18000-63:2021, Clause 6
This clause specifies conformance tests for product built according to ISO/IEC 18000-63:2021, Clause 6:
— conformance requirements for physical interactions (the signalling layer of the communications)
between Interrogators and Tags;
— conformance requirements for Interrogator and Tag operating procedures and commands.
Testing for this clause shall be done with the test setups as defined in Annex A.
All tests are defined in Table 1; the column M/O indicates either mandatory (M) or optional (O).
NOTE 1 In case an error condition has multiple choices for the error codes, either of the error codes is valid
and the test has to be evaluated as pass for any of these codes.

For conformance evaluation, as in Table 1, the following conformance test methods shall apply:
— By design: for Protocol requirements that are verified by design, the method of technical analysis is
at the discretion of the product vendor and, except in special cases, is not specified by this document.
In general, the technical analysis shall have sufficient rigor and technical depth to be accepted by a
test engineer knowledgeable of the Protocol that the requirement has been met.
— By demonstration: for Protocol requirements that are verified by demonstration, the test conditions
are specified by this document.
NOTE 2 A competent demonstrator typically complies with ISO/IEC 17025.
— As implemented: if a Tag or Interrogator implements a subset of the Protocol, conformance shall be
verified over the subset that is implemented. For example, although Interrogators may implement
DSB-ASK, SSB-ASK or PR-ASK modulation, a manufacturer may choose to only implement DSB-ASK
modulation. In this case, conformance testing shall only use DSB-ASK modulation. For parameters
that are continuously variable, conformance shall be verified at the minimum and maximum values
of the implemented range, unless the test conditions specifically state otherwise.
