33 ELECTROMECHANICAL ELEMENTARY RELAYS –
35 Part 7-9: Climatic Tests
37 FOREWORD
38 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
39 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
40 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
41 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
42 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
43 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
44 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
45 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
46 Standardization (ISO) in accordance with conditions determined by agreement between the two or ganizations.
47 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
48 consensus of opinion on the relevant subjects since each technical committee has representation from all
49 interested IEC National Committees.
50 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
51 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
52 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
53 misinterpretation by any end user.
54 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
55 transparently to the maximum extent possible in their national and regional publications. Any divergence between
56 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
57 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
58 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
59 services carried out by independent certification bodies.
60 6) All users should ensure that they have the latest edition of this publication.
61 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
62 members of its technical committees and IEC National Committees for any personal injury, propert y damage or
63 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
64 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
65 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
66 indispensable for the correct application of this publication.
67 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
68 rights. IEC shall not be held responsible for identifying any or all such patent rights.
69 The International Standards of the IEC 61810 have been prepared by IEC technical committee
70 94: All-or-nothing electrical relays.
71 The text of this International Standard is based on the following documents:
CD CC
94/799/CD 94/949/CC
73 Full information on the voting for the approval of this International Standard can be found in the
74 report on voting indicated in the above table.

76 A list of all parts of IEC 61810 series, published under the general title Electromechanical
77 elementary relays, can be found on the IEC website.

122 4 Test procedure
123 4.1 Purpose
124 To determine the ability of the relay to withstand certain climatic test conditions, or a sequence
125 of such climatic test conditions. For this purpose, the individual climatic tests described under
126 4.2.2 to 4.2.6 hereinafter may be carried out as separate tests. However, when a climatic
127 sequence is required, this sequence shall be as specified below. The damp heat steady state
128 test is to assess the suitability of the relay for use and/or storage under conditions of high
129 relative humidity.
