11、IEC 7811-8:2014(E) 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 Stand

12、ards 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

13、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 i

14、s 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 poss

Major changes from the first edition are as follows: The primary standard cards held by Q-Card are used to calibrate the manufacture of secondary reference cards. Other

17、primary standard cards held by PTB and Card testing International (CTI) are used as backup to replace cards held by Q-Card as they wear out. The supplier of secondary reference cards has changed from PTB to Q-Card. ISO/IEC 7811 consists of the following parts, under general title Ident if icat ion c

19、BS ISO/IEC 7811-8:2014ISO/IEC 7811-8:2014(E) Introduction This part of ISO/IEC 7811 is similar to ISO/IEC 7811-2, except that its higher coercivity requires higher energy to encode the data. The user of ISO/IEC 7811-8 is encouraged to review the entire standard for revisions and updates. The major d

20、ifferences from ISO/IEC 7811-2 are listed below. In terms of coercivity, this part of ISO/IEC 7811 media (51,7 kA/m, 650 Oe) is between ISO/IEC 7811- 2 (23,9 kA/m, 300 Oe) and ISO/IEC 7811-6 (minimum 199 kA/m, 2 500 Oe). The primary application for 51,7 kA/m (650 Oe) is for hotel guest room entry sy

21、stems worldwide. For Table 1 values, this part of ISO/IEC 7811 specifies different values for I min(6,5 FR) and I max(8 FR). Encoding techniques, specification, and error detection are not specified in this part of ISO/IEC 7811. Wherever possible, the same definitions, criteria, and test methods are

22、 used in ISO/IEC 7811-2, ISO/IEC 7811-6, and this part of ISO/IEC 7811. Notes in this part of ISO/IEC 7811 are only used for giving additional information intended to assist understanding or use, and do not contain provisions or requirements to which it is necessary to conform in order to be able to

23、 claim compliance with this part of ISO/IEC 7811.

24、fication cards as defined in Clause 4 of this part of ISO/IEC 7811, and the use of such cards for international interchange. This part of ISO/IEC 7811 specifies requirements for a 51,7 kA/m (650 Oe) magnetic stripe (including any protective overlay) on an identification card. The encoding technique

25、and coded character sets are not defined, however, the specifications of ISO/IEC 7811-2 may be used. It takes into consideration both human and machine aspects and states minimum requirements. Coercivity influences many of the quantities specified in this part of ISO/IEC 7811. It has a nominal value

26、 of 51,7 kA/m (650 Oe), but is not itself specified. Exposure of the card to a magnetic field is likely to destroy the recorded data. This International Standard provides criteria to which cards are to perform. No consideration is given within this International Standard to the amount of use, if any

27、, experienced by the card prior to test. Failure to conform to specified criteria is negotiated between the involved parties. ISO/IEC 10373-2 specifies the test procedures used to check cards against the parameters specified in this part of ISO/IEC 7811. Numeric values in the SI and/or Imperial meas

28、urement system in this part of ISO/IEC 7811 may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two are not to be intermixed or reconverted. The original design was made using the Imperial measurement system. 2 Conform

29、ance A prerequisite for conformance with this part of ISO/IEC 7811 is conformance with ISO/IEC 7810. An identification card is in conformance with this part of ISO/IEC 7811 if it meets all mandatory requirements specified herein. Default values apply if no others are specified. 3 Normative reference
