88 Integration method of radiocommunication device into an equipment
90 FOREWORD
91 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
92 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
93 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
94 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
95 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
96 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
97 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
98 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
99 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
100 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
101 consensus of opinion on the relevant subjects since each technical committee has representation from all
102 interested IEC National Committees.
103 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
104 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
105 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
106 misinterpretation by any end user.
107 4) In order to promote international uniformity, IEC National Committees undertake to app ly IEC Publications
108 transparently to the maximum extent possible in their national and regional publications. Any divergence between
109 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
110 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
111 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
112 services carried out by independent certification bodies.
113 6) All users should ensure that they have the latest edition of this publication.
