International, governmental and non-governmental orga
10、nizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on te
11、chnical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published
12、 in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum exten
13、t possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equi

19、onents is operated in accordance with the statutes of the IEC and under the authority of the IEC. The object of this system is to define quality assessment procedures in such a manner that electronic components released by one participating country as conforming with the requirements of an applicabl
20、e specification are equally acceptable in all other participating countries without the need for further testing. This blank detail specification is one of a series of blank detail specifications for semiconductor devices and shall be used with the following IEC publications: IEC 60747-10/QC 700000:

27、Throughout this standard, texts given in square brackets are intended for guidance to the specification writer and shall not be included in the detail specification. Throughout this standard, when a characteristic or rating applies, “x“ denotes that a value shall be inserted in the detailed specific
28、ation. If there is family specification, the number and title of this specification shall be given here, and whatever characteristics are quoted in this family specification should be omitted in clause 6. If there is not a family specification, “none“ should be stated here. Page7 BSIEC60748212:2001
