National bodies that ar
13、e 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 internation
14、al organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. In the field of information technology, ISO and IEC have established a joint technic
15、al committee, ISO/IEC JTC 1. 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. ISO/IEC 7811 consists of the following
16、parts, under the general title Identification cards Recording technique: Part 1: Embossing Part 2: Magnetic stripe Low coercivity Part 6: Magnetic stripe High coercivity Part 7: Magnetic stripe High coercivity, high density Part 8: Magnetic stripe Coercivity of 51,7 kA/m (650 Oe) ISO/IEC 7811-8 was
17、prepared by JTC 1, Information technology, SC 17, Cards and personal identification. It 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 majo
18、r differences from ISO/IEC 7811-2 are listed below. a) In terms of coercivity, ISO/IEC 7811-8 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, 2500 Oe). b) The primary application for 51,7 kA/m (650 Oe) is for hotel guest-room entry system
19、s worldwide. c) ISO/IEC 7811-8 specifies the “window” to be used to establish Table 1 values for 51,7 kA/m (650 Oe) media. The main difference being in the Imin (6,5 FR) and Imax (8 FR) values which define the extremities of the window. d) Encoding techniques, specification and error detection are n
20、ot specified in this part of ISO/IEC 7811. e) Wherever possible, the same definitions, criteria and test methods are used in ISO/IEC 7811-2, ISO/IEC 7811-6, and ISO/IEC 7811-8.

This part of ISO/IEC 7811 specifies requirements for a 51,7 kA/m (650 Oe) magnetic stripe (including any protective overlay) on an identificati
