9、or 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 o
10、rganization 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 tech
11、nology, 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 Standar
12、ds 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 sub
13、ject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 10373-7 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 17, Cards and personal identification. This second edition cancels and repl
14、aces the first edition (ISO/IEC 10373-7:2001), Clause 5 and subclause 6.3.5 of which have been technically revised. ISO/IEC 10373 consists of the following parts, under the general title Identification cards Test methods: Part 1: General characteristics Part 2: Cards with magnetic stripes Part 3: In
15、tegrated circuit(s) cards with contacts and related interface devices Part 5: Optical memory cards Part 6: Proximity cards Part 7: Vicinity cards BS ISO/IEC 10373-7:20081 Identification cards Test methods Part 7: Vicinity cards 1 Scope ISO/IEC 10373 defines test methods for characteristics of identi
16、fication cards according to the definition given in ISO/IEC 7810. Each test method is cross-referenced to one or more base standards, which may be ISO/IEC 7810 or one or more of the supplementary standards that define the information storage technologies employed in identification card applications.
17、 NOTE 1 Criteria for acceptability do not form part of ISO/IEC 10373, but will be found in the International Standards mentioned above. NOTE 2 Test methods defined in ISO/IEC 10373 are intended to be performed separately. A given card is not required to pass through all the tests sequentially. This
18、part of ISO/IEC 10373 deals with test methods, which are specific to contactless integrated circuit card (vicinity card) technology. ISO/IEC 10373-1 deals with test methods which are common to one or more ICC technologies and other parts deal with other technology-specific tests. Unless otherwise sp
19、ecified, the tests in this part of ISO/IEC 10373 apply exclusively to vicinity cards defined in ISO/IEC 15693-1 and ISO/IEC 15693-2. 2 Normative reference(s) The following referenced documents are indispensable for the application of this document.

BS ISO/IEC 10373-7:20085 6 Test apparatus and test circuits This clause defines
37、 the test apparatus and test circuits for verifying the operation of a VICC or a VCD according to ISO/IEC 15693-2. The test apparatus includes: calibration coil (see 6.1), test VCD assembly (see 6.2), reference VICC (see 6.3), digital sampling oscilloscope (see 6.4). 6.1 Calibration coil This subcla
38、use defines the size, thickness and characteristics of the calibration coil. 6.1.1 Size of the calibration coil card The calibration coil card consists of an area, which has the height and width defined in ISO/IEC 7810 for ID-1 type containing a single turn coil concentric with the card outline. Coi

It shall be constructed of a suitable insulating material. 6.1.3 Coil characteristics The coil o
40、n the calibration coil card shall have one turn. The outer size of the coil shall be 72 mm ( 2%) 42 mm ( 2%) with corner radius 5 mm. NOTE 1 The area over which the field is integrated is approximately 3000 mm 2 . The coil is made as a printed coil on PCB plated with 35 m copper. Track width shall b

A high impedance oscilloscope probe (e.g. 1MOhm, 14pF) shall be used to measure the (open circuit) voltage in the coil. The resona
42、nce frequency of the whole set (calibration coil, connecting leads and probe) shall be above 60 MHz. BS ISO/IEC 10373-7:20086 NOTE 3 A parasitic capacitance of the probe assembly of less than 35 pF normally ensures a resonant frequency for the whole set of greater than 60 MHz. The open circuit calib
43、ration factor for this coil is 0,32 V (rms) per A/m (rms) Equivalent to 900 mV (peak-to- peak) per A/m (rms). 6.2 Test VCD assembly The test VCD assembly for load modulation consists of a 150 mm diameter VCD antenna and two parallel sense coils: sense coil a and sense coil b. The test set-up is show
44、n in Figure 4. The sense coils are connected such that the signal from one coil is in opposite phase to the other. The 10 Ohm potentiometer P1 serves to fine adjust the balance point when the sense coils are not loaded by a VICC or any magnetically coupled circuit. The capacitive load of the probe i

46、er spacing of the sense coils in comparison to the set-up in ISO/IEC 10373-6 into account. In order to avoid any unintended misalignment in case of an unsymmetrical set-up the tuning range of the potentiometer P1 is only 10 . If the set-up cannot be compensated by the 10 potentiometer P1 the overall
47、 symmetry of the set-up should be checked. The capacitance of the connections and oscilloscope probe should be kept to a minimum for reproducibility. The high impedance oscilloscope probe ground connection should be as short as possible, less than 20 mm or coaxial connection. 6.2.1 Test VCD antenna
48、The Test VCD antenna shall have a diameter of 150 mm and its construction shall conform to the drawings in Annex A. The tuning of the antenna may be accomplished with the procedure given in Annex B. BS ISO/IEC 10373-7:20087 6.2.2 Sense coils The size of the sense coils is 100 x 70 mm. The sense coil
49、 construction shall conform to the drawings in Annex C. 6.2.3 Assembly of test VCD The sense coils and test VCD antenna are assembled parallel and with the sense and antenna coils coaxial and such that the distance between the active conductors is 100 mm as in Figure 5. The distance between the coil in the DUT and the calibration coil shall be equal with re
