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

90 1 Scope
91 This part of IEC 61810-7 is used for testing along with the appropriate severities and conditions
92 for measurements and tests designed to assess the ability of specimens to perform under
93 expected conditions of transportation, storage and all aspects of operational use.
94 The object of this test is to define a standard test method for resistance to soldering heat and
95 solderability for standard soldering processes.

118 4 Test procedure
119 These standard methods are a basic qualification for the resistance of solder processes under
120 standard conditions or individually as defined by the manufacturer.
121 NOTE The final product fitting the selected solder process must be investigated by the user under their responsibility.
122 NOTE The conditions of IEC60068-2-20 are recommended, but if soldering is difficult, the conditions shall be stated
123 individually by the manufacturer.
124 Any deviate from the given test conditions or process shall be explicitly described in the test
125 report. In such case it is not allowed to reference a test as according to this document.
126 In case of any deviation the test report shall be named as “similar to”.

128 To determine the ability of relay terminals
129 • the ability of relay terminals to wet easily with solder,
130 • and/or the ability of the relay to withstand soldering heat
131 Solder terminals and their supports shall have a sufficient resistance to any soldering heat.
132 These tests are only applicable to relays and to relays where the manufacturer has specified
133 the ability of terminations to a soldering process.
