36 FOREWORD
37 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
38 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
39 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC
40 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and
41 Guides (hereafter referred to as "IEC Publication(s)"). Their preparation is entrusted to technical committees; any IEC
42 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
43 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
44 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
45 the two organizations.
46 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
47 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
48 Committees.
49 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
50 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
51 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
52 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
53 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
54 the corresponding national or regional publication shall be clearly indicated in the latter.
55 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
56 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
57 independent certification bodies.
58 6) All users should ensure that they have the latest edition of this publication.
59 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
60 technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature
61 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,
62 or reliance upon, this IEC Publication or any other IEC Publications.
63 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
64 for the correct application of this publication.
65 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
66 IEC shall not be held responsible for identifying any or all such patent rights.
67 The International Standards of the IEC 61810 have been prepared by IEC technical committee
68 94: All-or-nothing electrical relays.
69 The text of this International Standard is based on the following documents:
CD CC
94/885/CD 94/959/CC

74 A list of all parts of IEC 61810 series, published under the general title Electromechanical
75 elementary relays, can be found on the IEC website.
76 This International Standard is to be used in conjunction with IEC 61810-1:2015.
77 The committee has decided that the contents of this document will remain unchanged until the
78 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
79 the specific document. At this date, the document will be

91 1 Scope
92 This part of IEC 61810-7 is used for testing along with the appropriate severities and conditions
93 for measurements and tests designed to assess the ability of specimens to perform under
94 expected conditions of transportation, storage and all aspects of operational use.
95 The object of this test is to define a standard test method for heating.

116 4 Test procedure
117 4.1 Purpose
118 To determine that the temperature rise of given relay parts does not exceed the specified limits.
119 4.2 Procedure
120 Set-up
121 The relay shall be mounted and energized as follows, unless otherwise specified.
122 a) Test procedure A – Group mounting: The test is carried out with three relays mounted side by side
123 in the same direction according Annex A
124 NOTE see IEC 61810-1, Table 5 – procedure A.
125 Test procedure B – Single mounting: The test is carried out with one relay
126 NOTE see IEC 61810-1, Table 5 –test procedure B.
127 Unless specifically designed otherwise, the specimen are tested in horizontal position with the
128 terminals pointing downward. The mounting distance shall be stated by the manufacturer.
129 b) Terminal screws and/or nuts are tightened with a torque equal to two-thirds of that specified in
130 IEC 60999-1.
131 c) In case of screwless terminals, care is to be taken to ensure that the conductors are correctly fitted
132 to the terminals in accordance with IEC 60999-1.
133 d) The relays shall be mounted in a sufficiently large heat chamber without forced convection. When
134 an air circulating test chamber is used for testing, baffles shall be provided within the test
135 chamber, unless all other conditions in this clause are met.
136 e) The specimen shall be protected against air draught and is not allowed to be subjected to any
137 artificial cooling.
138 f) During the test, the predetermined ambient temperature of the heat chamber shall not be
139 influenced by the relay or at least reduced to a minimum for high-capacity relays.
140 NOTE Especially for high capacity relays the influence could potentially not excluded.
141 g) The ambient temperature shall be constantly at room temperatur
