74 FOREWORD
75 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
76 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
77 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
78 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
79 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
80 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
81 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
82 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
83 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
84 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
85 consensus of opinion on the relevant subjects since each technical committee has representation from all
86 interested IEC National Committees.
87 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
88 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
89 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
90 misinterpretation by any end user.
91 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
92 transparently to the maximum extent possible in their national and regional publications. Any divergence between
93 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
94 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
95 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
96 services carried out by independent certification bodies.
97 6) All users should ensure that they have the latest edition of this publication.
98 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
99 members of its technical committees and IEC National Committees for any personal injury, property damage or
100 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
101 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
102 Publications.
103 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
104 indispensable for the correct application of this publication.
105 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
106 rights. IEC shall not be held responsible for identifying any or all such patent rights.
107 IEC 63316 was prepared by IEC Technical Committee 108, Safety of electronic equipment within
