52 FOREWORD

53 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national

54 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all

55 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC

56 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and

57 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National

58 Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-

59 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the

60 International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two

61 organizations.

62 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of

63 opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

64 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that

65 sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot

66 be held responsible for the way in which they are used or for any misinterpretation by any end user.

67 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the

68 maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the

69 corresponding national or regional publication shall be clearly indicated in the latter.

70 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment

71 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by

72 independent certification bodies.

73 6) All users should ensure that they have the latest edition of this publication.

74 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its

75 technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature

76 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or

77 reliance upon, this IEC Publication or any other IEC Publications.

78 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is indispensable for

79 the correct application of this publication.

80 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC

81 shall not be held responsible for identifying any or all such patent rights.

153 NOTE 1 to entry: “Spatial” means that receiving devices will take various positions and postures,

154 and will lead to variable transfer efficiency including almost zero percent. This situation may

155 occur when receiving devices are placed far apart from power source and freely rearranged.
