12、LOSSARY Part 4-4：Materials Materials for Surface Acoustic Wave(SAW)devices FOREWORD 1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprising all national electrotechnical committees(IEC National Committees).The object of IEC is to promote interna
13、tional co-operation on all questions concerning standardization in the electrical and electronic fields.To this end and in addition to other activities,IEC publishes International Standards,Technical Specifications,Technical Reports,Publicly Available Specifications(PAS)and Guides(hereafter referred
14、 to as“IEC Publication(s)”).Their preparation is entrusted to technical committees;any IEC National 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 pre
15、paration.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 IEC on technical matters express,as nearly as possible,an international consensus
16、of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.3)IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense.While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate,IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.4)In order to promot
