17、gts seredevrForeword 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 th
18、rough 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, al
19、so 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 pr
20、epare 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. In exceptional circumstances, the joi
21、nt technical committee may propose the publication of a Technical Report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical development or wh
22、ere for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type 3, when the joint technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for examp
23、le). Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid
24、 or useful. 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 TR 18047-4, which is a Technical Report of type 2, was prepared by Joint
25、Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. ISO/IEC TR 18047 consists of the following parts, under the general title Information technology Radio frequency identification device conformance test methods: Part 3
26、: Test methods for air interface communications at 13,56 MHz Part 4: Test methods for air interface communications at 2,45 GHz Test methods for air interface communications below 135 kHz, at 860 MHz to 960 MHz, and at 433 MHz will form the subjects of the future Parts 2, 6 and 7, respectively.

The
28、purpose of this part of ISO/IEC TR 18047 is to provide a test method for ISO/IEC 18000-4. This part of ISO/IEC TR 18047 contains all compliance measurements required to be fulfilled by a product in order to be compliant to 18000-4 Mode 2.

30、onformance of radio frequency identification devices (tags and interrogators) for item management with the specifications given in the corresponding part of ISO/IEC 18000, but does not apply to the testing of conformity with regulatory or similar requirements. The test methods require only that the
31、mandatory functions, and any optional functions which are implemented, be verified. This may, 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 part
32、 of ISO/IEC TR 18047 are: mode-specific conformance parameters including nominal values and tolerances; parameters that apply directly affecting system functionality and inter-operability. The following are not included in this part of ISO/IEC TR 18047: parameters that are already included in regula
33、tory test requirements; high-level data encoding conformance test parameters (these are specified in ISO/IEC 15962). Unless otherwise specified, the tests in this part of ISO/IEC TR 18047 apply exclusively to RFID tags and interrogator defined in ISO/IEC 18000-4 Mode 2. 2 Normative references The fo

The results of these tests shall be compared with the parameters spe
39、cified in ISO/IEC 18000-4 to determine whether the interrogator or tag under test conforms. 5.1 Default items applicable to the test methods 5.1.1 Test environment Unless otherwise specified, testing shall take place in an environment of temperature 23 C 3 C (73 F 5 F) and relative humidity of 40 %
40、to 60 %. 5.1.2 Pre-conditioning Where pre-conditioning is required by the test method, the tags and interrogators to be tested shall be conditioned to the test environment for an appropriate period of time before testing. 5.1.3 Default tolerance Unless otherwise specified, a default tolerance of 5 %
41、 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). 5.1.4 Total measurement uncertainty The total measurement uncertainty for each quantity determined by these t
42、est methods shall be stated in the test report. NOTE Basic information is given in “ISO Guide to the Expression of Uncertainty in Measurement”, ISBN 92-67-10188-9, 1993.

43、e 2 The long-range, high data-rate RFID system specified in ISO/IEC 18000-4 is designed for long-range operation. Therefore a good receiver characteristic on both sides interrogator and tag (if applicable) is useful. The range of an RFID system also depends on the output power of the interrogator, w
44、hich is set according to regulatory limits and application needs. Therefore receiver sensitivity and transmitter output power measurements are not part of this part of ISO/IEC TR 18047. 5.2.1 Test set-up and measurement equipment for Mode 2 This clause defines the test set-up and measurement equipme
45、nt for verifying the operation of a tag or an interrogator according to ISO/IEC 18000-4. Test results shall not be influenced by the set-up method of the test. Test set-ups include: test set-up for interrogator testing (see 5.2.1.1), test set-up for tag testing (see 5.2.1.2), test equipment (see 5.2
46、.1.3). These are described in the following subclauses. 5.2.1.1 Test set-up for interrogator testing An interrogator with integral antenna(s) shall be equipped with temporary antenna connector(s), or coupling device(s) i.e. sense antenna(s) shall be used to connect to the test equipment. A sense ant
47、enna shall not affect test results; appropriate distances (e.g. 30 cm), antenna sizes and types (e.g. patch antenna), as well as antenna polarization (i.e. circular polarization) shall be used. The antenna configuration and distance shall be included in the test report. To set up an interrogator wit
48、h the appropriate test pattern and operational modes one of two methods shall be used (combinations shall also be possible): an implemented test mode, a tag for initializing the appropriate operational mode. The air interface parameter in a test mode shall behave the same as the air interface parame
49、ter during normal usage. Unless otherwise stated the following frequencies shall be used for all tests. The frequency of the reference carrier shall be set to f RC,nom. i = (2931+i)*f CH , where f CH= 819,2 kHz; the frequency of the communication carrier shall be set to f CC, nom. i = (2944+i)*f CH . All tests shall be performed at channels i = 0, 43, 86. The output power
