42 FOREWORD
43 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
44 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
45 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
46 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
47 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
48 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
49 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
50 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
51 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
52 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
53 consensus of opinion on the relevant subjects since each technical committee has representation from all
54 interested IEC National Committees.
55 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
56 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
57 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
58 misinterpretation by any end user.
59 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
60 transparently to the maximum extent possible in their national and regional publications. Any divergence between
61 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
62 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
63 declared to be in conformity with an IEC Publication.
64 6) All users should ensure that they have the latest edition of this publication.
65 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
66 members of its technical committees and IEC National Committees for any personal injury, property damage or
67 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
68 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
69 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
70 indispensable for the correct application of this publication.
71 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
72 rights. IEC shall not be held responsible for identifying any or all such patent rights.
73 International Standard IEC 61300-2-33 has been prepared by subcommittee 86B: Fibre optic
74 interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
75 This fourth edition cancels and replaces the third edition published in 2012. It constitutes a
76 technical revision.
77 This edition includes the following significant technical changes with respect to the previous
78 edition:
79 a) Terms and definitions updated according to IEC 61753-1:2018 and IEC 61756-1:2019;
80 b) Test severities updated according to new edition of IEC 61753-1:2018.
81 c) Procedure D added for verification of the sealing performance after frequent mating and
82 demating of a hardened connector

FDIS Report on voting
86B/xxxx/FDIS 86B/xxxx/RVD
87 Full information on the voting for the approval of this standard can be found in the report on
88 voting indicated in the above table.
89 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
90 The list of all parts of IEC 61300 series, published under the general title, Fibre optic
91 interconnecting devices and passive components – Basic test and measurement procedures,
92 can be found on the IEC website.
93 The committee has decided that the contents of this publication will remain unchanged until the
94 stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related
95 to the specific publication. At this date, the publication will be
96 • reconfirmed;
97 • withdrawn;
98 • replaced by a revised edition, or
99 • amended.
The National Committees are requested to note that for this publication the stability date is 2020.

106 Part 2-33: Tests – Assembly and disassembly
107 of fibre optic mechanical splices, fibre management systems, protective
108 housings and hardened connectors
112 1 Scope
113 This part of IEC 61300, evaluates the assembly and disassembly of a fibre optic mechanical
114 splice, a fibre management system, a protective housing or a hardend connector for a specified
115 number of times.
117 The test procedures simulate the following conditions which can be found in the component
118 service lifetime:
119 - the ability of an optical mechanical splice to be re-installed after disassembly;
120 - the ability to re-enter fibre management systems and protective housings, accessing
121 fibres and optical components and making reconfigurations without disturbing
122 transmission in adjacent fibre circuits;
123 - verification of the sealing performance after frequent opening and closing of the
124 protective housing;
125 - verification of the sealing performance after frequent mating and demating of the
126 hardened connector.
