43 FOREWORD

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

45 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-

46 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to

47 other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available

48 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical

49 committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.

50 International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.

51 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions

52 determined by agreement between the two organizations.

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

54 consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC

55 National Committees.

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

57 in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate,

58 IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.

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

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

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

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

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

64 independent certification bodies.

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

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

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

68 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the

69 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

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

71 indispensable for the correct application of this publication.

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

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

74 International Standard IEC 61557-7 has been prepared by IEC technical committee 85: Measuring

75 equipment for electrical and electromagnetic quantities.

76 This third edition cancels and replaces the second edition published in 2007. This edition constitutes a

77 minor revision.

78 This edition includes the following changes with respect to the previous edition:

79 a) Alignment of the structure to the whole series IEC61557

80 b) Updated requirements in 4.3 in accordance to new standard editions of IEC 61010

81 and IEC 61010-031
82 c) Information on the marking is complemented
83 d) Information on the operating instructions is complemented
84 e) Information on the testing of leads is complemented
