58 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

59 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

60 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

61 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

62 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

63 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

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

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

66 with the International Organization for Standardization (ISO) in accordance with conditions determined by

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

69 consensus of opinion on the relevant subjects since each technical committee has representation from all

71 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

72 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

73 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

75 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

76 transparently to the maximum extent possible in their national and regional publications. Any divergence

77 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

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

80 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

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

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

84 members of its technical committees and IEC National Committees for any personal injury, property damage or

85 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

86 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

88 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

108 When a particular subclause of IEC 61326-1 is not mentioned in this part, that subclause

109 applies as far as is reasonable. When this standard states “addition”, “modification” or

110 “replacement”, the relevant text in IEC 61326-1 is to be adapted accordingly.
