National b
12、odies that are members of IS0 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. IS0 and I EC technical committees collaborate in fields of mutual interest. Oth
13、er international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rule
14、s given in the ISO/IEC Directives, Part 3. 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 appr
15、oval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this Amendment may be the subject of patent rights.

19、ough contact VCC: - 5 V under class A, - 3 V under class B, - 1,8 V under class C. The card shall support one or more consecutive classes and shall operate in interface devices offering one or more of those classes. No card shall be damaged when operated under classes not supported by the card (by d
20、efinition, a damaged card no longer operates as specified or contains corrupt data). However, some cards conforming to ISO/IEC 7816-3: 1989 could be damaged when operating under classes other than A and should be used only under class A operating conditions. 4.2.2 Selection of the class of operating
21、 conditions The interface device applies a class to the card (see figure 1). If the card provides an Answer-to-Reset with a class indicator (see 6.5.6), and the interface device is applying a class supported by the card, then normal operation may continue. Alternatively, the interface device may dea
22、ctivate the card and after a delay of at least 1 O ms, apply another class supported by the card. If the card provides an Answer-to-Reset without a class indicator, then the interface device shall maintain the current class. If, after the answer to reset, the card does not operate, then another clas
23、s may be applied. O ISOIIEC 2002 -All rights reserved 1 ISO/IEC 781 6-3:1997/Amd.l:2002( E) Conditions Class A Class B Class C Class A, at maximum allowed frequency Class B, at maximum allowed frequency Class C, at maximum allowed frequency When the clock is stopped (see 5.3.4) If the card does not
24、provide an Answer-to-Reset, then the interface device shall deactivate the card. The interface device should perform one of the following two actions after a delay of at least 1 Oms: - apply another class, if any; - abort the selection process. After abortion of a selection process, another selectio
25、n process may be initiated. If the interface device supports more than one class, the order in which the classes are applied is not within the scope of this part of ISO/IEC 7816.
