73 FOREWORD

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

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

76 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

77 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

78 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

79 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

80 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

81 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

82 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

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

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

85 interested IEC National Committees.

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

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

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

89 misinterpretation by any end user.

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

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

92 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

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

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

95 services carried out by independent certification bodies.

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

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

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

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

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

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

102 indispensable for the correct application of this publication.

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

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

105 International Standard IEC 61249-2-51 has been prepared by IEC technical committee 91,

106 Electronics assembly technology.
107 The text of this International Standard is based on the following documents:
