11、NT Part 6-1: Blank detail specification: Surface mount preset potentiometers Assessment level E FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of
12、 the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National
13、Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (IS
14、O) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representati
15、on from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published 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 t
16、o promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clea
17、rly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standar
18、d may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60393-6-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. The text of this standard is based on t
19、he following documents: FDIS Report on voting 40/1289/FDIS 40/1325/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Blank D
20、etail Specification is to be used in conjunction with IEC 60393-1:1989 and IEC 60393-6:2003. The committee has decided that the contents of this publication will remain unchanged until 2008. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bi
21、lingual version of this publication may be issued at a later date.60393-6-1 IEC:2003(E) 3 POTENTIOMETERS FOR USE IN ELECTRONIC EQUIPMENT Part 6-1: Blank detail specification: Surface mount preset potentiometers Assessment level E INTRODUCTION Blank Detail Specification A Blank Detail Specification i
