39 FOREWORD
40 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
41 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
42 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
43 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
44 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
45 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
46 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
47 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
48 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
49 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
50 consensus of opinion on the relevant subjects since each technical committee has representation from all
51 interested IEC National Committees.
52 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
53 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
54 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
55 misinterpretation by any end user.
56 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
57 transparently to the maximum extent possible in their national and regional publications. Any divergence between
58 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
59 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
60 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
61 services carried out by independent certification bodies.
62 6) All users should ensure that they have the latest edition of this publication.
63 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
64 members of its technical committees and IEC National Committees for any personal injury, property damage or
65 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
66 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
67 Publications.
68 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
69 indispensable for the correct application of this publication.
70 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
71 rights. IEC shall not be held responsible for identifying any or all such patent rights.
72 IEC 61300-2-19 has been prepared by subcommittee SC86B: Fibre optic interconnecting
73 devices and passive components, of IEC technical committee 86: Fibre optics. It is an
74 International Standard.
75 This fourth edition cancels and replaces the third edition published in 2012. This edition
76 constitutes a technical revision.
77 This edition includes the following significant technical changes with respect to the previous
78 edition:
79 a) Adoption of the information from IEC 60068-2-78
80 The text of this International Standard is based on the following documents:

82 Full information on the voting for its approval can be found in the report on voting indicated in
83 the above table.
84 The language used for the development of this International Standard is English.
85 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
86 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
87 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
88 described in greater detail at www.iec.ch/publications.
89 The committee has decided that the contents of this document will remain unchanged until the
90 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
91 specific document. At this date, the document will be
92 • reconfirmed,
93 • withdrawn,
94 • replaced by a revised edition, or
95 • amended.

97 INTRODUCTION
98 This part of IEC 61300 provides a test method of high humidity at constant temperature without
99 condensation on the DUT over a prescribed period. This test is performed to evaluate the
100 specimen as it is influenced by the absorption and diffusion of moisture and moisture vapour.

104 BASIC TEST AND MEASUREMENT PROCEDURES
106 Part 2-19: Tests – Damp heat (steady state)
110 1 Scope
111 This part of IEC 61300 details a procedure for determining the suitability of a fibre optic device
112 to withstand the environmental condition of high humidity and high temperature which can occur
113 in actual use, storage and/or transport. The test is primarily intended to permit the observation
114 of effects of high humidity at constant temperature over a given period. Absorption of moisture
115 may result in swelling that would destroy functional utility, cause loss of physical strength, and
116 cause changes in other important mechanical properties. Degradation of optical properties may
117 also occur. Although not necessarily intended as a simulated tropical test, this test can,
118 nevertheless, be useful in determining moisture absorption of insulating or covering materials.
