75 Part 1: General requirements
79 FOREWORD
80 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
81 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
82 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
83 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
84 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
85 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
86 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
87 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
88 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
89 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
90 consensus of opinion on the relevant subjects since each technical committee has representation from all
91 interested IEC National Committees.
92 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
93 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
94 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
95 misinterpretation by any end user.
96 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
97 transparently to the maximum extent possible in their national and regional publications. Any divergence between
98 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
99 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
100 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
101 services carried out by independent certification bodies.
102 6) All users should ensure that they have the latest edition of this publication.
103 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
104 members of its technical committees and IEC National Committees for any personal injury, property damage or
105 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
106 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
107 Publications.
108 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
109 indispensable for the correct application of this publication.
110 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
111 rights. IEC shall not be held responsible for identifying any or all such patent rights.
112 IEC 63349-1 has been prepared by IEC technical committee 82: Solar photovoltaic energy
113 systems. It is an International standard.
114 The text of this International Standard is based on the following documents:

116 Full information on the voting for its approval can be found in the report on voting indicated in
117 the above table.
118 The language used for the development of this International Standard is English.
119 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
120 accordance with ISO/IEC Directives, Part 1 and ISO/IE
