47 FOREWORD
48 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
49 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
50 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
51 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
52 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
53 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
54 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
55 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
56 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all
59 interested IEC National Committees.
60 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
61 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
62 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
63 misinterpretation by any end user.
64 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
65 transparently to the maximum extent possible in their national and regional publications. Any divergence between
66 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
75 Publications.
76 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
77 indispensable for the correct application of this publication.
78 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
79 rights. IEC shall not be held responsible for identifying any or all such patent rights.
80 IEC 61810-7 has been prepared by subcommittee WG3: Maintenance of basic relay standards,

109 1 Scope
110 This part of IEC 61810-7 is used for testing all kind of relays within the scope of technical
111 committee 94 and shall evaluate their ability to perform under expected conditions of
112 transportation, storage and all aspects of operational use.
113 The tests stated here within shall be done with test conditions and appropriate severities, as
114 well as suitable measurements conditions.
115 The object of this test is to define a standard test method to ensure that the DUT performs
116 satisfactorily at its specified energization values throughout the defined temperature range.
117 The standard is to prove the capability of the DUT to function during and/or after several stress
118 situations, that may occur in service, during handling or during transportation. This part
119 comprises test procedures to simulate shock impacts, steady acceleration environments (such
120 as moving vehicles, aircraft and projectiles) as well as vibration conditions.
121 Those procedures provide evidence about the structural integrity of DUTs and their
122 electromechanical design robustness. Based on the chosen test severity, the procedures may
123 also be used to deliberately reveal mechanical weaknesses of DUTs and allow grouping of parts
124 acc. to their stress resistance levels.
125 The tests are mainly intended for specimen without packaging. However, if the packaging is
126 considered an essential part of the specimen, then certain tests like shock tests may be carried
127 out with packaging as well.

163 4 Test procedure
164 4.1 General
165 4.1.1 General purpose
166 The standard describes three different test procedure
167 • Shock,
168 • Acceleration and
169 • Vibration.
170 Shock tests may be used to characterize the robustness of the DUT with regard to transportation
171 impacts (e.g. drop events, handling) or whenever the application is subject to rather seldom
172 shock impacts. Shocks create a wide-band excitation of the specimen, not limited to specific
173 frequencies. By that, the shock test also helps to understand the structural integrity of the DUT,
174 if it is tested without packaging.
175 Acceleration tests may be used to characterise the robustness of the DUT with regard to
176 continuous acceleration stress during its service life. Typical applications are aircrafts, rotating
177 machinery as well as the automotive sector. The acceleration tests represent permanent steady
178 forces to the DUT interior, giving insight into its structural integrity.
179 Vibration tests may be used to characterise the robustness of the DUT with regard to expected
180 frequency ranges, by provoking particular resonance frequencies. This may be relevant for
181 automotive applications as well as any kind of transportation stress. Further, environmental
182 conditions like off-shore installations may represent significant vibration throughout life as well
183 as rotating machines or any moving equipment nearby the DUT installation. The vibration tests
184 apply sine-wave forces to the DUT and its interior, creating a particular stress on any joints and
185 connection elements between the structural components.
186 4.1.2 General conditions
