25 Part 7-11: Enclosure Protection and Degree of Protection
27 FOREWORD
28 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization
29 comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to p
30 2) romote international co-operation on all questions concerning standardization in the electrical and electronic
31 fields. To this end and in addition to other activities, IEC publishes International Standards, Technical
32 Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred
33 to as "IEC Publication(s)"). Their preparation is entrusted to technical committees; any IEC National
34 Committee interested in the subject dealt with may participate in this preparatory work. International,
35 governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
36 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with
37 conditions determined by agreement between the two organizations.
38 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
39 consensus of opinion on the relevant subjects since each technical committee has representation from all
40 interested IEC National Committees.
41 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
42 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
43 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
44 misinterpretation by any end user.
45 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
46 transparently to the maximum extent possible in their national and regional publications. Any divergence between
47 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
48 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
49 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
50 services carried out by independent certification bodies.
51 6) All users should ensure that they have the latest edition of this publication.
52 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
53 members of its technical committees and IEC National Committees for any personal injury, property damage or
54 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
55 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
56 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
57 indispensable for the correct application of this publication.
58 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
59 rights. IEC shall not be held responsible for identifying any or all such patent rights.
60 The International Standards of the IEC 61810 have been prepared by IEC technical committee
61 94: All-or-nothing electrical relays.
62 The text of this International Standard is based on the following documents:

86 1 Scope
87 This part of IEC 61810-7 is used for testing along with the appropriate severities and conditions
88 for measurements and tests designed to assess the ability of specimens to perform under
89 expected conditions of transportation, storage and all aspects of operational use.
90 The object of this test is to define standard test methods for appropriate enclosure sealing
91 testing.

114 4 Test procedure
115 4.1 Purpose
116 To determine the effectiveness of the relay enclosure in regard to either sealing or protection
117 against ingress of dust and water.

123 relay shall be mounted with standard mounting position pin down if not otherwise specified in
124 the test chamber. The air pressure within the relay shall be that of the ambient air pressure in
125 the test chamber (category 2 enclosure). The relay shall be subjected to talc (hydrated
126 magnesium silicate) for 8 h. After a recovery period of 2 h under normal atmospheric conditions
127 and after cleaning (removal of external surface dust) the test samples shall be submitted to
128 visual and functional measurement.
129 Conditions to be specified
130 The conditions to be specified are the following:
131 a) pressure reduction inside the relay, if required;
132 b) position of the relay, if other than normal operating position;

135 A suitable soldering process in accordance with manufacturer specification shall be chosen out
136 of IEC 61810-7-15 and all test specimens shall go through the selected soldering process.
137 Procedure 1 for RTIII relays
138 The sealing test shall be made by immersion in a liquid at a temperature equal to the upper
139 limit of the operating temperature range of the relay (with a tolerance of –0 K/+5 K) in
140 accordance with test Qc, method 1 or 2 of IEC 60068-2-17. Immersion times shorter than
141 10 min may be specified by the manufacturer. Bubbles shall not exceed the limits given in

143 Procedure 2 for RT IV and V for relays
144 The helium detection test shall be carried out in accordance with test Qk, method 1 or 2 of
145 IEC 60068-2-17. Where procedure 2 is used and the existence of a gross leak cannot be ruled
146 out, it shall be followed by procedure 1.
147 For a detailed description of the Helium sniffer test see Annex A
148 NOTE The helium leak rate is not equal to the leak rate of the gases normally used within sealed relays.
149 If the time interval between sealing and testing has been more than 48 h, the relay shall be
150 exposed to an atmosphere of helium at high pressure.
151 The difference pressure and the duration of exposure shall be as prescribed by the
152 manufacturer.
