8 AMENDMENT 1
10 FOREWORD
11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
12 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation on all
13 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities ,
14 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
15 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
16 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
17 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
18 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
19 the two organizations.
20 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
21 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
22 Committees.
23 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
24 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
25 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
26 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
27 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
28 the corresponding national or regional publication shall be clearly indicated in the latter.
29 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
30 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
31 independent certification bodies.
32 6) All users should ensure that they have the latest edition of this publication.
33 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
34 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
35 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publicatio n,
36 use of, or reliance upon, this IEC Publication or any other IEC Publications.
37 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
38 for the correct application of this publication.
39 9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IEC
40 shall not be held responsible for identifying any or all such patent rights.
41 Amendment 1 to IEC 61800-5-1:2022 has been prepared by subcommittee 22G: Adjustable speed
42 electric power drive systems (PDS), of IEC technical committee 22: Power electronic systems and
43 equipment.

95 The clearance and creepage distance paths in the presence of a cemented joint between two insulating
96 parts are determined as follows.
97 For cemented joint of Type 1 protection:
98 • the cemented joint is not considered to be similar to solid insulation with respect to clearance and
99 creepage distance measurements, however the pollution degree within the joint itself is pollution
100 degree 1. See clause D.1. Examples are given in Figures D.6 – D.9.

103 For cemented joint of Type 2 protection:
104 • the cemented joint is considered to be similar to solid insulation with respect to clearance and
105 creepage distance measurements. An example is given in Figure D.5.

This publication has been withdrawn.

106 • the distance through the cemented joint (i.e. the thickness of the material relative to the shortest
107 distance between live parts) shall not be less than that specified in IEC 60664-3:2016, Table 1,
108 which is reproduced as Table O.1.
109 • the cemented joint shall comply with the test requirements of 5.2.5.6.
111 Note: The concept of Type 1 and Type 2 protection are similar to the concepts specified in IEC 60664-3:2016.
113 A cemented joint that is not evaluated as providing protection of Type 1 or Type 2 is neither considered
114 solid insulation nor to reduce pollution degree. The clearance and creepage distances of 4.4.7.4 and
