Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 18046-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This first edition (ISO/IEC 18046-1) cancels and replaces the first edition (ISO/IEC 18046:2006).
ISO/IEC 18046 consists of the following parts, under the general title Information technology — Radio
frequency identification device performance test methods:
 Part 1: Test methods for system performance
 Part 2: Test methods for interrogator performance
 Part 3: Test methods for tag performance

Introduction
RFID technology has broad applicability to the Automatic Identification and Data Capture (AIDC) industry in
item management. As a wireless communication technique based on Radio Frequency technology the
applications cover multiple levels of the industrial, commercial and retail supply chains. These can include:
 freight containers,
 returnable Transport Items (RTI),
 transport units,
 product packaging, and
 product tagging.
Performance tests define test methods that deliver results that allow the comparison of different RFID
systems, interrogator and tags in order to select among them for use in a particular application.
The performance characteristics of devices (tags and interrogation equipment) can vary drastically due to
application factors as well as the particular RFID air interface (frequency, modulation, protocol, etc.) being
supported. Of key concern is the matching of the various performance characteristics to the user application.
Additionally, in an open environment users of such technology demand multiple sources for these devices
from technology providers. A key challenge is a method of evaluating the differences between various
technology providers' products in a consistent and equitable manner.
This part of ISO/IEC 18046 provides a framework for meeting the above noted concern and challenges. To
this end, clear definitions of performance as related to user application of RFID technology in the supply chain
are provided. Based on such application-based definitions, test methods are defined with attention to the test
parameters required for a consistent evaluation of RFID devices.
Of particular significance, these tests are defined for RFID devices having one antenna. It is common practice
to have products with both single and multiple antennas to define an RFID transaction zone sufficient for the
application. The defined methods can easily be extended from equipment with a single antenna to apply to
equipment with multiple antennas, in order to evaluate performance under conditions more closely matching
those of a particular application.

3- If the 90% read or 100% read is not obtained, the test shall be stopped after a time equivalent to
t = 5 X t@80%
4- This test shall be performed for different positions of the tags population as required by the
application. Each position shall be recorded in the test report.
5- The test shall be repeated for each tag arrangement.
Note: if 80% read is not reached, the time to reach the maximum percentage read shall be
recorded as well as the maximum number of tags read.
The test will be stopped if 80% of the tags are not read within 10 seconds.

6.2.4.4 Test report
The test report shall give the time to reach 80%, 90% and 100 % of the tag population.
The general parameters of the test shall be recorded according to the Table given in Annex A.

Figure 12 — Test setup for identification Speed motion for tag population
The interrogator will be set on a fixed part of the test bench.
The tag will be fixed on a mobile part of the test bench so that the best coupling configuration will be
maintained during the displacement of the interrogator.
6.2.5.3 Test procedure
The interrogator shall be set in relation to the tag and in accordance with radio frequency local regulations.
